5.3 Building GCC: the directory that should contain system headers does not exist.2.3 Linux Users building a System Compiler.MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package. If you want to use the toolchains (with installed libraries) outside of the MSYS2 environment, all you need to do is add /mingw64/bin or /mingw32/bin to your PATH. Verify that the compiler is working by doing gcc -version Only use unprefixed packages for misc command-line utilities (such as grep, sed, make, etc), unless you know what you're doing. Make sure any compilers and libraries you install have this package prefix ( mingw-w64-x86_64- for 64-bit or mingw-w64-i686- for 32-bit). You can search the repositories by doing pacman -Ss name_of_something_i_want_to_installĪnd install using pacman -S package_name_of_something_i_want_to_installĪnd from then on the GSL library will be automatically found by your compiler! Install any libraries/tools you may need. This includes GCC (the compiler), GDB (the debugger), and more. You should routinely update your installation.Ī) for 64-bit: pacman -S mingw-w64-x86_64-toolchainī) for 32-bit: pacman -S mingw-w64-i686-toolchain If it closes itself during the update, restart it and repeat the same command to finish the update. If done correctly, the terminal prompt will say MINGW64 or MINGW32 respectively, not MSYS. I myself am not sure about why this happens (I think it has something to do with Sourceforge URL redirection or whatever that the installer currently can't handle properly enough).Īnyways, if you're already planning on using MSYS2, there's no need for that installer.Īfter the install completes, click on the newly created "MSYS2 Shell" option under either MSYS2 64-bit or MSYS2 32-bit in the Start menu (or mingw64.exe or mingw32.exe in the installation directory). Unfortunately, the MinGW-w64 installer you used sometimes has this issue.
