Mixxx compilation ignores PKG_CONFIG_PATH

[nh2]

If you try and compile Mixx with custom libraries (e.g. a newer portaudio than is available from you package repositories), e.g.

    PKG_CONFIG_PATH=$HOME/opt/mixxx/lib/pkgconfig scons prefix=$HOME/opt/mixxx

then the compilation doesn't find it; scons seems to completely ignore the PKG_CONFIG_PATH environment variable.

That makes testing out new versions of Mixxx very hard.

The problem is Mixxx doesn't really use pkg-config except for a few libraries here and there. So it's not that your version is not getting picked up for portaudio. It's that Mixxx is just assuming portaudio headers are on the include path and -lportaudio is in the link path.

For a workaround you can define your CFLAGS/CXXFLAGS/LDFLAGS to point to point to the new version of portaudio.

Thanks, that worked!

I used:

export PKG_CONFIG_PATH=$HOME/opt/mixxx/lib/pkgconfig
export INCLUDE_PATH=$HOME/opt/mixxx/include
export LDFLAGS=-L$HOME/opt/mixxx/lib/
export CXXFLAGS=-I$HOME/opt/mixxx/include

scons useenv=yes

I think this should be mentioned at least in
http://www.mixxx.org/wiki/doku.php/compiling_on_linux.
