UZDoom compile error using MSYS2

Post by shoober420 »

when compiling uzdoom from current git master commit (https://github.com/UZDoom/UZDoom/commit ... 4897819819) on the latest MSYS2-x86_64-20250830 using Windows 11, i get this compile error (this is after doing as drfrag said with i_xinput.cpp file). full build log here (https://gitlab.com/shoober420/game-conf ... gerror.txt)

ive done the following as outlined in this post by drfrag and still get the same error

[quote=drfrag post_id=1264344 time=1763971878 user_id=570]

Below // HEADER FILES and #include <limits.h> add #include <math.h> in /src/common/platform/win32/i_xinput.cpp. But it's better to use Visual Studio anyway.

You could try adding it to the other file too.
im now presented with a new build error

i see "#include <math.h>" is already present in the p_map.cpp file. is this missing another #include or is this something else?

Re: UZDoom compile error using MSYS2

Post by drfrag »

No, this time is a serious problem. That line is old code but seems someone has made a change to that operator and i'm afraid i cannot help. You could create an issue on GitHub. Besides those compiling instructions on the zdoom wiki are obsolete, you should use those on GitHub.
