Bugzilla Bug 237020

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

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". So the correct include should be:

#include "SDL/SDL.h"

Reproducible: Always

Steps to Reproduce:
I only tried to emerge flightgear on my ~amd64 machine:
1.) emerge flightgear
2.) watch flightgear failing with the above mentioned error...

Created an attachment (id=164861) [details]
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

plib-1.8.5 build.log

Created an attachment (id=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.
