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. ;)
