This repository is a collection of binaries to create your own GNU Toolchain usable in Windows. The trunk of the master branch contains the sum of the latest versions of all binaries.

Binaries are provided for the following programs:

• GCC 7
• GCC 8
• GCC 9
• GCC 10
• GCC 11
• GCC Trunk (12)
• make
• binutils
• gdb
• MinGW

All binaries are 64 bit but the toolchain and debugger can produce and debug 32 Bit code as well

Executable without a prefix produce and handle 64 Bit Code. Executables with the prefix i686-w64-mingw32 produce and handle 32 Bit Code.

Only need a particular GCC version for your toolchain?

Checkout the branches:

• GCC-7
• GCC-8
• GCC-9
• GCC-10
• GCC-11

for smaller readily available toolchains.

Features compiled in are:

• GCC:
  • Modules support in GCC-11
  • Shared and static versions of runtime libraries such as libstdc++. By default programs are linked against shared versions. use the -static flag to compile against the static versions
  • Link Time Optimization support
  • C, C++, Fortran, ObjC, ObjC++ and D
  • OpenMP support
  • Quad Precision Math support
  • C++11 Threading using pthreads
  • Support for GCC Plugins
  • zstd LTO compression
  • iconv charset support
  • Version specific runtimes: Allows multiple GCC installations to live next to each other. This is done using version prefixes to runtime folders as well as version suffixes for each program. E.g. Executable of GCC 9 is called gcc-9. To create a symlink for the default version of gcc you want to use run one of the make-gcc-*-*-default.bat which will create symlinks such as gcc.exe and others (master branch only).
• binutils:
  • Plugin support (needed for LTO)
• gdb:
  • Pretty Printer support thanks to Python 2.7 statically linked into the binary
  • gdbserver
  • multi-arch support allowing debugging any target supported by gdb when remote debugging
  • iconv charset support
  • Minidebuginfo support with lzma compression
  • Precise floating point emulation with MPFR and GMP
• MinGW:
  • Posix Threading
  • Default windows version of 0x601 (Windows 7)
  • MSVCRT Runtime instead of ucrt (Needed by e.g. Golang compiler)
  • Builds of winpthreads and winstorecompat

If you have any problems with the configuration used or are in need of any additional options and settings feel free to open an issue.

All binaries are either fully relocatable or only have a dependency on libwinpthread-1.dll. For GCC to function it requires the folder it's located in (the bin folder) to be in the system PATH.
