libopenmpt Error 1

[JanQ]

CXX libopenmpt123/libopenmpt123.cpp
CROSS_COMPILE Badness: /usr/include in INCLUDEPATH: /usr/include/SDL
cc1plus: internal compile error: in add_path, at inpath.c.462

Makefile:909: recipe for target openmpt123.o failed

[Rudi]

Please try the attached patch. It disables building the openmpt123
executable, which we do not need anyway (we only want the shared libs).

Indeed, but we need to know why sdl config is bad


can you post too the logs when you build adding this patch (verbose build)

Well, SDL is not specified as dependency for libopenmpt. So if the target platform does
not use SDL at all (Raspberry, Cubox-i, Utilite) or the SDL devpackage has not (yet)
been installed, it might pick a host instance...

OK...I test more.... IMHO.. before libopenmpt need compile flac, libsound.
It work's.

Yes, but the problem is that SDL is not installed here but it works.
I 'll check is the host is installed or not ...

Could it be that our pkg-config is searching /usr/lib/pkgconfig in case a *.pc file was
not found in $PKG_CONFIG_PATH ?

Especially, since 'get_meta' (config/functions line 115) unsets $PKG_CONFIG_LIBDIR...

Replying to myself:

> not found in $PKG_CONFIG_PATH ?

Yes, it does :(

This appears to be a bug: PKG_CONFIG_LIBDIR should be preserved as well. In line 33 we
set it to "" to avoid the problem above, but shoot ourselves in the foot by killing the
variable here.


So the reason for the "CROSS_COMPILE Badness" error is that on this build machine there
must be an "sdl.pc" in /usr/lib/pgkconfig or maybe in /usr/local/lib/pkgconfig and our
pkg-config is finding it when it should not.


The missing dependencies are another story. The openmpt123 executable may use
SDL2/SDL/PortAudio, FLAC and libsndfile. However, we do not need this executable.
Currently we are building it, but it doesn't get installed/packaged since all we want is
libopenmpt.so.*. So we won't loose much if we disable openmpt123 as suggested earlier.
