Date: Mon, 23 Feb 2004 23:29:20 -0500 From: "Brian Kropf" Subject: [SDL] Windx5 I was wondering if I could suggest a change for (at least) the mingw/msys build. Every time I do the ./configure, make on a fresh download it crashes when it tries to find directx.h for the audio portion of the build In file included from SDL_dx5audio.c:37: SDL_dx5audio.h:31:21: directx.h: No such file or directory In file included from SDL_dx5audio.c:37: I usually copy the directx.h from the video/windx5 into the audio/windx5 and things go smoothly after that; just thought I'd suggest it for making future builds go smoothly. ;)
