A compiler suite is what Code::Blocks uses to turn the code you type into it into numbers that the computer understands.  As a compiler is a very complex undertaking it is not part of Code::Blocks itself but rather is a separate project that Code::Blocks then uses.  The specific compiler toolchain talked about in this page is a "MinGW" compilerThat means "Minimalist GCC for Windows."  And "GCC" expands to "GNU Compiler Collection."  There are many MinGW-based compiler suites, on this page we will concentrate on TDM-GCC.

== GCC Compiler Toolchain Features ==
+
For most MinGW-based compiler toolchains, having your toolchain in your PATH is important because it means that during development the toolchain libraries will be accessible by default to your programs as you develop them and also makes it easier to use utilities such as [https://cmake.org/ CMake] as they will be able to find your compiler toolchainWhen you actually distribute your programs to other computers then you will copy the needed .dll files out of your toolchain directory and include them as part of your installer. On your machine they are in your PATH so you always have them, on your users computers they won't have the compiler toolchain so there you provide the .dll files with your program.
 
 
Various GCC compilers for Windows come with different features and which flavor of the compiler you end up choosing should reflect your specific needs.
 
 
 
=== Threads: Win32, Posix ===
 
 
 
There are two major threading models to choose from:
 
 
 
* win32 threads will not give you C++11 multithreading features.
 
* posix threads enable C++11 multithreading features.  It will make your resulting executable depend on your compiler's libwinpthreads included Dynamic Link LibraryAs a result you will have to distribute that library with your executable.  If you want to use standard C++11 threading then choose posix.
 
 
 
Using one threading model or the other is not mutually exclusive, you can directly call each others API regardless of which model your compiler uses.
 
 
 
=== Exceptions: DW2 (DWARF-2), setjmp/longjmp, SEH ===
 
 
 
There are three major exception models to choose from:
 
 
 
* DWARF (DW2, dwarf-2): 32-bit only.  No permanent runtime overhead, needs whole call stack to be dwarf-enabled, which means exceptions cannot be thrown through Windows system DLLs for example.
 
 
 
* SJLJ (setjmp/longjmp): available for 32 bit and 64 bit – not “zero-cost”: even if an exception isn’t thrown, it incurs a minor performance penalty (~15% in exception heavy code) – allows exceptions to traverse through Windows callbacks and system DLLs.
 
 
 
* SEH exceptions: unlike SJLJ, have zero overhead penalty. 64-bit only.

Overview

A compiler toolchain is what Code::Blocks uses to turn the code you type into it into numbers that the computer understands. As a compiler toolchain is a very complex undertaking it is not part of Code::Blocks itself but rather is a separate project that Code::Blocks then uses. The kind of compiler toolchains talked about on this page are "MinGW" toolchains. Which means "Minimalist GNU for Windows." And "GNU" expands to "GNU's Not Unix." More information about the GNU project can be found on the GNU Home Page.

For most MinGW-based compiler toolchains, having your toolchain in your PATH is important because it means that during development the toolchain libraries will be accessible by default to your programs as you develop them and also makes it easier to use utilities such as CMake as they will be able to find your compiler toolchain. When you actually distribute your programs to other computers then you will copy the needed .dll files out of your toolchain directory and include them as part of your installer. On your machine they are in your PATH so you always have them, on your users computers they won't have the compiler toolchain so there you provide the .dll files with your program.

TDM-GCC

TDM-GCC is the toolchain that will be used as the example for this guide. TDM-GCC statically links the required toolchain libraries into your final executable. Which means that when you create your installer for your final program there are less files to include - they are built into your executable itself. The Code::Blocks team recommends TDM-GCC.

Installation

Download the on-demand installer and run it.

Go through the installation pages, the red arrows are all the default options which we will be keeping and the last blue arrow is to indicate that you will be putting TDM-GCC into your system's PATH.

Once you are ready, click Install to proceed.

Code::Blocks Configuration

Go to your Compiler settings:

Compiler Settings.png

And then under the "Toolchain executables" tab (red arrow), click on the ellipsis ("...", blue arrow) and choose the root directory where you installed TDM-GCC 32-bit. Once you have that directory chosen, in the "Program Files" sub-tab (green arrow) area fill out the fields as shown. If you aren't using the TDM-GCC toolchain there might be minor variation in the executable names. If you choose the blue arrow ellipsis first then for each ellipsis you click on under "Program Files" you will already be in your TDM-GCC bin directory where the actual programs are.

Now, go to your Debugger settings:

Choose your default debugger (red arrow), and then fill in the Executable path for it as shown for TDM-GCC 32-bit (blue arrow).

Summary

You now have a Code::Blocks environment that is configured to use TDM-GCC 32-bit properly. Using this guide as a template you can easily set up alternative compiler toolchains no matter the source - just follow the same basic procedure.

Alternative MinGW Compiler Toolchains

MinGW - The original project.

MinGW-Builds ➡ In, "Toolchains targeting Win32 or Win64," ➡ "Personal Builds," ➡ "mingw-builds," ➡ Version, ➡ Threading Model, ➡ Exception Model, ➡ Revision.

Mingw-w64 - The parent project of MinGW-Builds, includes much more than is necessary - MinGW-Builds will usually suffice instead of the full works.

MinGW Equation - A package that also provides OpenMP.

Development Tools

Normally you should not need many of these tools. ZIP is convenient, especially when: building Code::Blocks itself, but other than that these tools only serve specialized purposes.
