Hi, this happened when I tried to compile games-simulation/flightgear-1.0.0 which depends on media-libs/plib: x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I. -I../../src/Include -I../.. -I../../src -I/usr/X11R6/include -march=opteron -mtune=opteron -O2 -finline-functions -pipe -D_REENTRANT -c -o aircraft.o aircraft.cxx In file included from /usr/include/plib/pu.h:1591, from ../../src/GUI/gui.h:36, from ../../src/Cockpit/hud.hxx:60, from aircraft.cxx:42: /usr/include/plib/puSDL.h:32:17: error: SDL.h: No such file or directory In file included from /usr/include/plib/pu.h:1591, from ../../src/GUI/gui.h:36, from ../../src/Cockpit/hud.hxx:60, from aircraft.cxx:42: /usr/include/plib/puSDL.h: In function 'void puGetWindowSizeSDL(int*, int*)': /usr/include/plib/puSDL.h:42: error: 'SDL_Surface' was not declared in this scope /usr/include/plib/puSDL.h:42: error: 'display' was not declared in this scope /usr/include/plib/puSDL.h:42: error: 'SDL_GetVideoSurface' was not declared in this scope make[2]: *** [aircraft.o] Error 1 make[2]: Leaving directory `/var/tmp/portage/games-simulation/flightgear-1.0.0/work/FlightGear-1.0.0/src/Aircraft' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/games-simulation/flightgear-1.0.0/work/FlightGear-1.0.0/src' make: *** [all-recursive] Error 1 I looked into "/usr/include/plib/pu.h" and it includes SDL.h this way: #include "SDL.h" which is wrong because the only SDL.h I have installed resides in "/usr/include/SDL/SDL.h".

Created attachment 164861 [details, diff] plib-1.8.5.ebuild.patch Possible fix. Some sed action which corrects the include during src_unpack()
Actually, as 'pkg-config sdl --cflags' returns: -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL the problem lies probably elsewhere (maybe something gets misdetected at configure).
whoops, fixed summary...
Please attach the full build log, and how about config.log from flightgear
Created attachment 164898 [details] plib-1.8.5 build.log
Created attachment 164899 [details] flightgear-1.0.0 config.log
"SDL.h" is the recommended way to use SDL. I patched the configure for flightgear to use sdl-config to pick up the include file directory.
