           Summary: some SDL programs won't compile because SDL_CONFIG isn't
                    set
           Product: Openembedded
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: trivial
          Priority: P4
         Component: Build

             nThis:

seen in the AM_PATH_SDL macro:
  PATH="$prefix/bin:$prefix/usr/bin:$PATH"
  AC_PATH_PROG(SDL_CONFIG, sdl-config, no, [$PATH])

since $prefix is usually /usr, configure gets the wrong sdl-config, the wrong
flags, etc...
.. unless SDL_CONFIG is set

My question is:
- should ALL .bb files for SDL programs include the line:
export SDL_CONFIG = "${STAGING_BINDIR}/sdl-config"
- or should the SDL_CONFIG variable be set in the build environment of all
programs to avoid such situations, where a package may build on some system and
break on others?

Note that if the maintainer doesn't have a native SDL installed, compilation
won't break... (this is probably what happened with libsdl-mixer, lbreakout and
supertux which I just fixed)
