I'm getting this error all over when compiling with MinGW and CMake on windows. Any ideas?

[Jupeyy]

fixed some MinGW stuff, and you try again and report back if it works now?

Now I am getting an error while linking:

mhh mingw32 is really strange, you can try: https://sourceforge.net/projects/mingw-w64/

cross compiling with mingw under linux works

[Jupeyy]

https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win32/Personal%20Builds/mingw-builds/installer/mingw-w64-install.exe thats the installer

[Jupeyy]

or if you want more linux like toolchain: https://www.msys2.org/ it has mingw64 support too

[Jupeyy]

seems like mingw64 is broken rn, get an internal compiler error on linux and with the mingw(over MSys2) setup pacman -S mingw-w64-x86_64-gcc pacman -S mingw-w64-x86_64-SDL2 pacman -S mingw-w64-x86_64-freetype pacman -S mingw-w64-x86_64-cmake pacman -S mingw-w64-x86_64-make

cmake .. -DCMAKE_LEGACY_CYGWIN_WIN32=1 make -j20 worked except the compilation error, on linux 32 bit works rn so probs on windows too, hope that help for 32 bit testing you have to replace x86_64 with i686 in the package names

also you have to start as mingw path C:\msys64\mingw32{64}.exe

I downloaded mysys2 and downloaded all of the dependencies following your steps but I have a few problems.

1. For this command: cmake .. -DCMAKE_LEGACY_CYGWIN_WIN32=1 I don't have cygwin installed. Do I need it? I get this warning when building without it: Manually-specified variables were not used by the project: CMAKE_LEGACY_CYGWIN_WIN32

2. The cmake command also appears to be building the project with VS Studio instead of MinGW. How do I get around this?

3. Even after running pacman -S mingw-w64-x86_64-make when I type make -j20 it tells me -bash: make: command not found. Am I supposed to add something to path?

[Jupeyy]

1. yes thats ok

2. you have to change your path variables so mingw/cmake/make is found before vs(or uninstall vs), other cmake or other make(maybe installed by VS)

3. ok maybe u have to type mingw-w64-x86_64-make instead of make

[NeverEndingCycle]

Alright, I've managed to get it working with some workarounds!

1. Moving the environment variable didn't do anything, but I was able to choose the generator by adding -G "MSYS Makefiles as an argument to the cmake command. (I also removed -DCMAKE_LEGACY_CYGWIN_WIN32=1 because it was unused.)

2. mingw-w64-x86_64-make didn't work, but I was able to get the original make command working by running pacman -S make instead.

3. After re-running everything compiled correctly (with a few warnings). Thanks again!

[Jupeyy]

1. it should only be unused when u didnt clean your build directory before

But good to hear :D

[NeverEndingCycle]

Alright, good to know.
