patch for the autotools build to work with Msys2/MinGW32
« on: May 16, 2024, 05:30:12 pm »
The Msys2 devs dont want it since they are deprecating win32 but for those of us who still use 32 bit sometimes this fixes the build.

the problem as noticed by others is that windres on 32 bit mingw gets passed -mthreads via the WX_CXXFLAGS flag.
changed it to WX_CPPFLAGS as both return the same minus the -mthreads flag.

Good! Simple but useful for me.
-Windows 7, 32-bit
-CodeBlocks r13518, gcc 13.2.0, debug version

Hi, reckless, long time no see. Thanks.

I'm not using the 32 bit windows system, some of my PCs are still Win7 64bit, and it seems msys2 are dropping support for those systems.

BTW, can you have a look at this post:

Code::Blocks / Tickets / #1461 Fix building codeblocks on MinGW-w64 aarch64

I'm still hoping Code::Blocks could be built under the MinGW64 port. (as you patch, it supports building C::B on the MinGW32 port)
If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

ah wait you mean for older OS like win7 ? well it should still be possible by setting the WIN32_WINNT flag to 0x601 and building it with mingw64.
i do have a prebuilt package you can try out if you want ?.
otherwise you probably have to build the package yourself but they did include mingw64 in the PKGBUILD now but it is not avaliable as a pacman package yet it seems.

here is the modified package build for codeblocks with both mingw32 and mingw64 added as well as 32 bit clang if someone prefers the ucrt build.

What github issue or pull request are you using? Can you share the links?

Or, you suggest pushing your contributions to the C::B's source base?

Thanks.

https://github.com/msys2/MINGW-packages/commit/ba7eac7846234a4d3f8f22f8d060ef85d4d6d749

this one, but since they dont intend on providing neither a mingw64 nor mingw32 build it might make more sense to just add the fix to C::B base ?.

one strange thing i noticed which might be interresting is that i use the TDM compiler (modified version by me) with msys2 and the static runtime version of wxwidgets 3.2 works out of the box  with the autotools build :o has'nt crashed once on me.
but if i use the standard windows build with the batch files it goes ape huh.

the TDM build i use was made for msys2 and unless using -static-libgcc -static-libstdc++ it works just like the normal msys2 mingw builds.
other than that i fixed a bug with the cleanup function which was leaking path handles to the exception mechanism if it failed to run and i changed the _onexit routine running the cleanup function to atexit using a wrapper.
