[Solved] Problem compiling SFML 2.3.2 with MinGW32

[gunchleoc]

Hi all,

I have a problem compiling under Windows 7, 64 bit with MinGW32. I used the current source code archive downloaded from the website. I get the same problem if I drop the pre-built GCC 4.9.2 MinGW (DW2) - 32-bit package into the appropriate path. It seems to be a problem with OpenGL, but couldn't find any solutions on the web. Any help would be appreciated

ETA: Problems occur with sfml‑window and sfml‑graphics only.

Commands used to build SFML:

$ mkdir build
$ cd build
$ cmake -G "MSYS Makefiles" ..
$ make sfml‑window

Seems like WINAPI is not defined (which it should be, when Windows headers are correctly included). The conditional compilation branch here only includes <windows.h> for MSVC, i.e. not in your case. Still, MinGW usually seems to work.

Why don't you use the MinGW Makefiles generator?
Why not make install?

Thanks for your fast reply

ETA: You hit the nail on he head - removing the #ifdef _MSC_VER fixed it.

MinGW doesn't work at all for me:

$ cmake -G "MinGW Makefiles" ..
CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.4/Modules/CMakeMinGWFi
ndMake.cmake:22 (message):
  sh.exe was found in your PATH, here:

  C:/MinGW/msys/1.0/bin/sh.exe

  For MinGW make to work correctly sh.exe must NOT be in your path.

  Run cmake from a shell that does not have sh.exe in your PATH.

  If you want to use a UNIX shell, then use MSYS Makefiles.

I have been unable to find out how to remove anything from PATH or Path. I went into the Control Panel to fix things up and remove it, but it's still there in MinGW. Opening a new Msys.bat didn't help there either.

make install has the exact same problem as make.

If you use MSYS you should also use the MSYS Makefiles generator.

[gunchleoc]

I have no idea how to do that - I'm a noob concerning MinGW. I usually do my stuff in Linux.

However, removing the #ifdef _MSC_VER in  include/SFML/OpenGL.hpp fixed it, so I can work from there

Thank you both for your help!

We should fix that in SFML. But I'm sure there's a reason for this #ifdef, and it seems to work for MinGW. How do MinGW and MSYS CMake generators behave differently in this respect?

[eXpl0it3r]

I've built SFML with a dozen different MinGW distros and never had issues, so I have to assume it's not a problem with SFML...

The difference between MinGW and MSYS is just that one complaints when sh.exe is in PATH and the other doesn't, or rather one made for MSYS and the other isn't.
