In order to sucesfully compile Code::Blocks, the wxWidgets (<u>wxGTK-2.6.1 or later</u>) cross-platform UI library <u>must be installed</u>. In this document, it is not assumed that it is already installed in your system and instructions are given on how to download, build and install it.
+
In order to successfully compile Code::Blocks, the [http://en.wikipedia.org/wiki/WxWidgets wxWidgets] User Interface library <u>must be installed</u>. For most Linux users, this is maybe the only dependency not already installed. wxWidget can be used directly on top of the X server, in this case the variant of the wxWidget library is called wxX11. However this library [http://wiki.wxwidgets.org/WxWidgets_Compared_To_Other_Toolkits#Why_You_Shouldn.27t_Use_wxWidgets is sub-par compared to other toolkits and unstable]. Hence Code::Blocks uses wxGTK, the version of wxWidget based on GTK+. The exact requirement is libwxGTK-2.8.0 or later (2.8.3 is not recommended because of some troubles). This creates an additional dependency on GTK+, consider the following:
What is '''not''' covered here, is the wxWidgets prerequisites. The most important being GTK2, of course!
 
Let me stress it here, while it's early: <u>GTK2 is required</u>, not GTK1, for Code::Blocks to be operational.
 
  
You do not need to Compile wxWidgets if your distribution has wxGTK 2.6 and wxGTK 2.6-dev package available.  A quick search for "wxGTK" through your respective package manager should show bring up the needed packages.  After you have installed successfully you can moving on the the Installing Code::Blocks portion.  If you are using Ubuntu and have installed the wxGTK package, you must also have the dev version as well as the "wx-common" package in order to successfully compile Code::Blocks.

A possible implementation which does not exist:  
  
All the instructions below, assume an existing directory named <tt>~/devel</tt>. If you 'll be using a different one, adjust the path to match.
+
''Code::Blocks  ->  wxWidgets (libwxX11)  ->  X''
 +
 
 +
Current Code::Blocks implementation:
 +
 
 +
''Code::Blocks  ->  '''wxWidgets (> libwxGTK2.8)'''  ->  '''GTK+ (> libgtk-x11-2.0)'''  ->  X''
 +
 
 +
This document helps you to install libwxGTK if necessary but does not cover the installation of GTK+. GTK+ is probably installed on your Linux anyway, so don't worry ;)

===wxGTK installation===
+
=== Checking the presence of GTK+ library ===
  
====Getting wxGTK====
+
Have a look in /usr/lib ( /usr/lib/x86_64-linux-gnu for 64 bits) for something like "libgtk-x11-2.0.so" (Note the library must be 2.0 minimum). Alternatively, do a search with your package manager or go to your Linux distribution forum for help. If you don't want to loose time, you can even forget this check since there is a good probability that everything is already installed.
  
Visit the [http://www.wxwidgets.org wxWidgets web site]. Click the "Download" button at the top of the page. Under wxWidgets 2.6.3 downloads, select wxGTK. Save the file in <tt>~/devel</tt>.
+
===Library wxGTK installation===
  
wxWidgets project has released two patches for 2.6.3 release. Click the "Patches" in the left side of the page. Download the Patch 2, either in zip or tar.gz format. Save the file in <tt>~/devel</tt>
+
==== Checking the presence of libwxGTK library ====
  
====Uncompressing the wxGTK sources====
+
In your package manager, look for 'libwxgtk' keyword and verify that '''all''' libwxgtk2.8 stuffs are installed. If you find the libraries uninstalled, just '''install them and go directly to [https://wiki.codeblocks.org/index.php?title=Installing_Code::Blocks_from_source_on_Linux#Code::Blocks_installation Code::Blocks installation]'''.
  
After the download finishes, switch to <tt>~/devel</tt>:
+
Alternatively you can do the same in the command line (the following is an example, there may be more than two packages):
  
<pre>cd ~/devel</pre>
+
<pre>$ ls /usr/lib/libwx_gtk* //to verify the presence
 +
$ sudo apt-get install libwxgtk2.8-dev
 +
$ sudo apt-get install libwxgtk2.8-0</pre>
  
Now, untar the wxGTK sources:
+
If you don't find any packages you must install the library from source as described below, and you can redo this check afterwards to verify that the installation worked correctly.
  
<pre>tar zxf wxGTK-2.6.3.tar.gz</pre>
 
  
Move the patch to the wxGTK directory
+
''Note for Debian and Ubuntu users:'' You can use
  
<pre>mv wxWidgets-2.6.3-Patch-2.tar.gz wxGTK-2.6.3</pre>
+
<pre>$ update-alternatives --config wx-config</pre>
  
or
+
to see which version of libwx is there or not and currently active.
  
<pre>mv wxWidgets-2.6.3-Patch-2.zip wxGTK-2.6.3</pre>
+
And, Debian and Ubuntu user can use this to add a value to the list of choices
  
Switch to the wxGTK directory
+
<pre>$ update-alternatives --install /usr/bin/wx-config wx-config /opt/wx/2.8/bin/wx-config 50</pre>
  
<pre>cd wxGTK-2.6.3</pre>
+
====Getting wxGTK sources====
  
Extract the patch
+
Visit the [http://www.wxwidgets.org wxWidgets web site]. Click the "Download" button at the top of the page. Under wxWidgets 2.8.7 downloads, select wxGTK. Save the file in <tt>~/devel</tt>. After the download finishes, switch to <tt>~/devel</tt>:
  
<pre>tar zxf wxWidgets-2.6.3-Patch-2.tar.gz</pre>
+
<pre>cd ~/devel</pre>
  
or
+
Now, untar the wxGTK sources:
 
 
<pre>unzip -fo wxWidgets-2.6.3-Patch-2.zip</pre>
 
 
 
Remove the patch file
 
  
<pre>rm wxWidgets-2.6.3-Patch-2.tar.gz</pre>
+
<pre>tar zxf wxGTK-2.8.7.tar.gz</pre>
  
or
+
Switch to the wxGTK directory:
  
<pre>rm wxWidgets-2.6.3-Patch-2.zip</pre>
+
<pre>cd wxGTK-2.8.7</pre>

You can get Code::Blocks source code in one of two ways:
+
You can get Code::Blocks source code [https://www.codeblocks.org/downloads/25 from the website as a tarball] or from the [https://www.codeblocks.org/downloads/7 SVN repository] (this second method is described below).
* Download the latest source package, or
 
* Get the latest sources from the SVN repository.
 
Both methods, are described below.
 
  
 +
=====From SVN repository=====
 +
NOTICE: The SourceForge CVS is no longer used although it still exists.
  
=====Downloading the latest source package=====
+
Enter your development directory:
 +
<pre>cd ~/devel</pre>
  
Go to the Code::Blocks [https://www.codeblocks.org web site] and download the latest source package. This would be the " Code::Blocks IDE version 1.0rc2 source code (tarball)" codeblocks-1.0rc2.tar.gz.
+
Then checkout the source using one of [https://www.codeblocks.org/downloads/7 these] methods. This will create the directory <tt>trunk</tt>. Change to the source code directory, by issuing the following command:
Save this file in <tt>~/devel</tt> and then untar it:
 
<pre>cd ~/devel
 
tar zxf codeblocks-1.0rc2.tar.gz</pre>
 
This will create the directory <tt>~/devel/codeblocks-1.0rc2</tt>.
 
Change to the source code directory, by issuing the following command:
 
<pre>cd codeblocks-1.0rc2</pre>
 
  
=====Getting the latest sources from SVN=====
+
<pre>cd trunk</pre>
'''IMPORTANT NOTICE: The Sourceforge CVS is no longer used although it still exists'''
 
  
Enter your development directory:
+
If you are a ''Gentoo'' user at this point, please see [[Compiling_Code::Blocks_in_Gentoo]].
<pre>cd ~/devel</pre>
 
  
Then checkout the source using one of [https://www.codeblocks.org/source_code.shtml these] methods.

Before beginning, it is often a good idea to check you have recent versions of autoconf and automake - repositories versions are not always recent enough. (if you do not have automake, then you will get "cannot find aclocal" error). If you're compiling the svn trunk versions of CodeBlocks (or future versions) then the unix build has switched to autotools. So first build wxWidgets as described above and then build CodeBlocks. In short, these commands build Code::Blocks from sources ''and'' installs it:
 +
<pre> ./bootstrap
 +
./configure
 +
make
 +
make install
 +
</pre>
  
This will create the directory <tt>trunk</tt>.
+
The long story is as follows: First run:
Change to the source code directory, by issuing the following command:
+
<pre> ./bootstrap</pre>
  
<pre>cd trunk</pre>
+
This sets up the configure script and its dependencies. It only needs to be run once (after downloading the source from svn).
  
====Building Code::Blocks RC2 and SVN====
+
'''If you get errors like (...):'''
 +
./bootstrap: libtoolize: not found
 +
...then install the "libtool" package using your package manager.
  
 +
./bootstrap: 64: ./bootstrap: aclocal: not found
 +
...then the "autoconf" and "automake" package using your package manager.
  
If you're compiling the svn trunk versions of CodeBlocks (or future versions) then the unix build has switched to autotools. So first build wxWidgets as described above and then build CodeBlocks as follows:
+
bad interpreter: File not found
 +
...then there exists a problem with DOS line-endings, for example if you cross compile to a Windows partition. Simply check-out a fresh copy of CodeBlocks from SVN.
 +
<br>
 +
Or, instead of downloading from SVN, you might consider using the little command line tool [http://dos2unix.sourceforge.net/ dos2unix], which normally comes with most distributions.
 +
<br>
  
./bootstrap
+
  (".infig.status: error: cannot find input file: Makefile")
 +
...(configure aborts with some unspecific error messagelike that), then you might consider also running dos2unix bootstrap acinclude.m4 codeblocks.pc.in configure.in Makefile.am before running bootstrap. Once you've run the bootstrap script, jump to next step.
  
This sets up the configure script and it's dependencies.  It only needs to be run once (after downloading the source from svn).  '''If you get errors like:'''
 
 
  aclocal:configure.in:61: warning: macro `AM_OPTIONS_WXCONFIG' not found in library
 
  aclocal:configure.in:61: warning: macro `AM_OPTIONS_WXCONFIG' not found in library
Then aclocal is having trouble finding the wxWidgets .m4 files.  You can do one of two things:

then there exists a problem with DOS line-endings. i had this error after i tried to build a  codeblocks from sources which were checked out with cvs on a windows machine. After i checked out a fresh copy of codeblocks from cvs under Ubuntu linux (see above topic: Downloading the latest source package fom SVN), all errors were gone.

The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'

...then this can be solved by something like:

  ACLOCAL_FLAGS="-I /usr/share/aclocal" ./bootstrap
<br>
+
(...maybe adopting the path, so use `wx-config --prefix` is necessary.)
If configure aborts with some unspecific error message(".infig.status: error: cannot find input file: Makefile"), you might consider also running
 
  dos2unix bootstrap acinclude.m4 codeblocks.pc.in configure.in Makefile.am
 
before running bootstrap
 
  
Once you've run the bootstrap script, installing is as simple as:
+
====Installing Code::Blocks sources====
./configure
+
You can read the BUILD file included in the source, but everything is very straightforward. Do:
 +
<pre> ./configure
 
  make
 
  make
  make install
+
  make install</pre>
 +
 
 +
You may need to run make install with super user rights, in that case use:
 +
<pre> sudo make install</pre>
 +
...for the last step.
 +
 
 +
If you have multiple versions of wxWidgets installed or kept them in place, you can use:
 +
./configure --with-wx-config=/path/to/wx-config
 +
 
 +
'''Note:''' The Nassi Shneiderman plugin (part of the contrib plugins) has a dependency on [http://www.boost.org boost] which is needed to compile this plugin. Boost does not need to be compiled therefore. It is not checked for the existing of boost at the moment (except for debian build-system, there it is a build-dependency), so if you configure C::B to be build without Nassi Schneiderman, it should not lead to problems in case you don't have/want boost.

'''Note for GCC 4.1.X users''' (for example SuSe 10.1) : there is an issue with GCC 4.1.X and SqPlus script binding engine; at the moment there are only partial workarounds (see forums). The easiest way to have C::B compiled is to install GCC 4.0.X as additional compiler. Here : http://www.mjmwired.net/resources/mjm-fedora-gcc.html you can find a simple way to do it. In order to compile C::B with the additional GCC, you must do the following, supposing you have installed gcc-4.0.3 in /opt/gcc/4.0.3 and compiled it with 403 suffix (see link above) :
+
====Resolving runtime issues====
  
  export CC=/opt/gcc/4.0.3/gcc403
+
When running Code::Blocks after the installation it might happen, that the system complains:
export CXX=/opt/gcc/4.0.3/g++403
+
  codeblocks: error while loading shared libraries: libcodeblocks.so.0: cannot open shared object file: No such file or directory
./configure --enable-contrib
+
In that case make sure the library path where the Code::Blocks libraries where installed into is "known" to the system. For example: On Ubuntu using a default build process on a clean system will install the Code::Blocks executables to /use/local/bin and the libraries to /usr/local/lib. The latter is usually not known to a "clean" Ubuntu system. To add it to the search path for libraries do the following (as root / using sudo respectively):
make
+
Add the following line to the file /etc/ld.so.conf:
 
+
  /usr/local/lib
====Building Code::Blocks RC1 and former====
+
...and run:
 
+
ldconfig
To build Code::Blocks all you have to do now is type:
+
That's it - Code::Blocks should now work just fine as all libraries are being found.
 
 
<pre>make -f Makefile.unix</pre>
 
 
 
This will build everything: the application and the plugins. The final step is to update the working environment for your system:
 
 
 
<pre>make -f Makefile.unix update</pre>
 
 
 
The following notes about converting the line endings does '''not''' apply to the CVS Version! The "update" script included there works just fine.
 
 
 
'''Important note:''' Don't run that final make yet! The "update" script seems to be using Dos character encoding, which will result in its failure to run on Linux. To fix this, use dos2unix:
 
 
 
To install it in Gentoo, do:
 
 
 
# emerge -av dos2unix
 
 
 
In Debian and Ubuntu, do (as root, or using sudo etc.):
 
 
 
# apt-get install sysutils
 
 
 
This will install dos2unix. Now we are ready to convert the script.
 
# dos2unix -n update update.unix
 
  # chmod +x update.unix
 
# ./update.unix
 
The first line converts the script character encoding, the second makes it executable and the third runs it. This trick is from a forum post by ilkapo.
 
 
 
OK. Now that the update script is converted to unix format, you can run the final make:
 
 
 
<pre>make -f Makefile.unix update</pre>
 
 
 
If everything's gone well, congratulations! You should be able to launch Code::Blocks by running the generated <tt>run.sh</tt> script in the <tt>output</tt> subdir:
 
 
 
<pre>output/run.sh</pre>
 
 
 
This script can be ran from anywhere in your system so, yes, you can make a shortcut to it on your desktop ;)
 
  
Enjoy!

Note that for both you may need super user rights again - so use the sudo command as needed.

These are instructions on how to build Code::Blocks under Linux. These instructions should work for all Linux distros, as we'll be installing from sources.

Prerequisites

In order to successfully compile Code::Blocks, the wxWidgets User Interface library must be installed. For most Linux users, this is maybe the only dependency not already installed. wxWidget can be used directly on top of the X server, in this case the variant of the wxWidget library is called wxX11. However this library is sub-par compared to other toolkits and unstable. Hence Code::Blocks uses wxGTK, the version of wxWidget based on GTK+. The exact requirement is libwxGTK-2.8.0 or later (2.8.3 is not recommended because of some troubles). This creates an additional dependency on GTK+, consider the following:

A possible implementation which does not exist:

Code::Blocks -> wxWidgets (libwxX11) -> X

Current Code::Blocks implementation:

Code::Blocks -> wxWidgets (> libwxGTK2.8) -> GTK+ (> libgtk-x11-2.0) -> X

This document helps you to install libwxGTK if necessary but does not cover the installation of GTK+. GTK+ is probably installed on your Linux anyway, so don't worry ;)


Note: All the instructions below, assume an existing directory named ~/devel. If you 'll be using a different one, adjust the path to match. As a first step create this directory:

mkdir ~/devel

Checking the presence of GTK+ library

Have a look in /usr/lib ( /usr/lib/x86_64-linux-gnu for 64 bits) for something like "libgtk-x11-2.0.so" (Note the library must be 2.0 minimum). Alternatively, do a search with your package manager or go to your Linux distribution forum for help. If you don't want to loose time, you can even forget this check since there is a good probability that everything is already installed.

Library wxGTK installation

Checking the presence of libwxGTK library

In your package manager, look for 'libwxgtk' keyword and verify that all libwxgtk2.8 stuffs are installed. If you find the libraries uninstalled, just install them and go directly to Code::Blocks installation.

Alternatively you can do the same in the command line (the following is an example, there may be more than two packages):

$ ls /usr/lib/libwx_gtk* //to verify the presence
$ sudo apt-get install libwxgtk2.8-dev
$ sudo apt-get install libwxgtk2.8-0

If you don't find any packages you must install the library from source as described below, and you can redo this check afterwards to verify that the installation worked correctly.


Note for Debian and Ubuntu users: You can use

$ update-alternatives --config wx-config

to see which version of libwx is there or not and currently active.

And, Debian and Ubuntu user can use this to add a value to the list of choices

$ update-alternatives --install /usr/bin/wx-config wx-config /opt/wx/2.8/bin/wx-config 50

Getting wxGTK sources

Visit the wxWidgets web site. Click the "Download" button at the top of the page. Under wxWidgets 2.8.7 downloads, select wxGTK. Save the file in ~/devel. After the download finishes, switch to ~/devel:

cd ~/devel

Now, untar the wxGTK sources:

tar zxf wxGTK-2.8.7.tar.gz

Switch to the wxGTK directory:

cd wxGTK-2.8.7

Building wxWidgets

Here we will create a separate build directory instead of building from the src directory, so that we can easily rebuild with different options (unicode / ansi, monolithic / many libs, etc).

The documentation says the default is for gtk2 to use unicode and wx > 2.5 to build as a monolithic library. This doesn't appear to be the case, so these flags are passed to configure:

mkdir build_gtk2_shared_monolithic_unicode
cd build_gtk2_shared_monolithic_unicode
../configure --prefix=/opt/wx/2.8 \
       --enable-xrc \
       --enable-monolithic \
       --enable-unicode
make
su
make install
exit

Add /opt/wx/2.8/bin to the PATH (if your shell is bash then edit /etc/profile or ~/.bash_profile) (On Suse 10.1 edit /etc/profile.local, it will only be available after a new login). An example PATH:

export PATH=/usr/bin:/opt/wx/2.8/bin:$PATH

Add /opt/wx/2.8/lib to /etc/ld.so.conf (nano /etc/ld.so.conf), then run:

ldconfig
source /etc/profile

That's it. Now the linker will look in /opt/wx/2.8/lib for wx libraries and you will have a monolithic shared library unicode build.

To check that things are working, type:

wx-config --prefix

which should give you /opt/wx/2.8

wx-config --libs

which should have at least:

-L/opt/wx/2.8/lib -lwx_gtk2-2.8

but can contain other flags as well.

which wx-config

should return /opt/wx/2.8/bin/wx-config

Code::Blocks installation

Getting Code::Blocks sources

You can get Code::Blocks source code from the website as a tarball or from the SVN repository (this second method is described below).

From SVN repository

NOTICE: The SourceForge CVS is no longer used although it still exists.

Enter your development directory:

cd ~/devel

Then checkout the source using one of these methods. This will create the directory trunk. Change to the source code directory, by issuing the following command:

cd trunk

If you are a Gentoo user at this point, please see Compiling_Code::Blocks_in_Gentoo.

Before beginning, it is often a good idea to check you have recent versions of autoconf and automake - repositories versions are not always recent enough. (if you do not have automake, then you will get "cannot find aclocal" error). If you're compiling the svn trunk versions of CodeBlocks (or future versions) then the unix build has switched to autotools. So first build wxWidgets as described above and then build CodeBlocks. In short, these commands build Code::Blocks from sources and installs it:

 ./bootstrap
 ./configure
 make
 make install

The long story is as follows: First run:

 ./bootstrap

This sets up the configure script and its dependencies. It only needs to be run once (after downloading the source from svn).

If you get errors like (...):

./bootstrap: libtoolize: not found

...then install the "libtool" package using your package manager.

./bootstrap: 64: ./bootstrap: aclocal: not found

...then the "autoconf" and "automake" package using your package manager.

bad interpreter: File not found

...then there exists a problem with DOS line-endings, for example if you cross compile to a Windows partition. Simply check-out a fresh copy of CodeBlocks from SVN.
Or, instead of downloading from SVN, you might consider using the little command line tool dos2unix, which normally comes with most distributions.

 (".infig.status: error: cannot find input file: Makefile")

...(configure aborts with some unspecific error messagelike that), then you might consider also running dos2unix bootstrap acinclude.m4 codeblocks.pc.in configure.in Makefile.am before running bootstrap. Once you've run the bootstrap script, jump to next step.

aclocal:configure.in:61: warning: macro `AM_OPTIONS_WXCONFIG' not found in library

...then aclocal is having trouble finding the wxWidgets .m4 files. You can do one of two things: To just get bootstrap to find the path this time do:

export ACLOCAL_FLAGS="-I `wx-config --prefix`/share/aclocal"

To change the aclocal search path more permanently do:

echo `wx-config --prefix`/share/aclocal >> /usr/share/aclocal/dirlist

Then aclocal will also search somewhere like /opt/wx/2.8/share/aclocal

Note for Ubuntu users: The above is not the correct way to fix the AM_* errors. Rather, you only need to install the package named "wx-common" (Universe repository).

The usual way to define `LIBTOOL' is to add `AC_PROG_LIBTOOL'

...then this can be solved by something like:

ACLOCAL_FLAGS="-I /usr/share/aclocal" ./bootstrap

(...maybe adopting the path, so use `wx-config --prefix` is necessary.)

Installing Code::Blocks sources

You can read the BUILD file included in the source, but everything is very straightforward. Do:

 ./configure
 make
 make install

You may need to run make install with super user rights, in that case use:

 sudo make install

...for the last step.

If you have multiple versions of wxWidgets installed or kept them in place, you can use:

./configure --with-wx-config=/path/to/wx-config

Note: The Nassi Shneiderman plugin (part of the contrib plugins) has a dependency on boost which is needed to compile this plugin. Boost does not need to be compiled therefore. It is not checked for the existing of boost at the moment (except for debian build-system, there it is a build-dependency), so if you configure C::B to be build without Nassi Schneiderman, it should not lead to problems in case you don't have/want boost.

To uninstall you can later run:

make uninstall

If you want to recompile everything, first run:

 make clean
 make distclean
 make clean-bin
 make clean-zipfiles

and then follow the above sequence for installing.

By default, CodeBlocks will install to /usr/local. If you want it in its own tree (so you can have multiple versions of CodeBlocks, each in its own subdirectory of /opt) replace the above ./configure command with:

 ./configure --prefix=/opt/codeblocks-svn

or similar. Then you can later install a different build like:

 ./configure --prefix=/opt/codeblocks2-svn

followed by 'make && make install' as usual.

By default, CodeBlocks will not compile the contributed plugins from SVN. If you want to compile / install them too, replace the above ./configure command with:

 ./configure --with-contrib-plugins=all

followed by 'make && make install' as usual.

To see a list of other options available for configuring the build of CodeBlocks do:

 ./configure --help

To compile under Gentoo, use:

 ./configure --with-wx-config=wx-config-2.8

Resolving runtime issues

When running Code::Blocks after the installation it might happen, that the system complains:

codeblocks: error while loading shared libraries: libcodeblocks.so.0: cannot open shared object file: No such file or directory

In that case make sure the library path where the Code::Blocks libraries where installed into is "known" to the system. For example: On Ubuntu using a default build process on a clean system will install the Code::Blocks executables to /use/local/bin and the libraries to /usr/local/lib. The latter is usually not known to a "clean" Ubuntu system. To add it to the search path for libraries do the following (as root / using sudo respectively): Add the following line to the file /etc/ld.so.conf:

/usr/local/lib

...and run:

ldconfig

That's it - Code::Blocks should now work just fine as all libraries are being found.

Note that for both you may need super user rights again - so use the sudo command as needed.
