jack doesn't work with pkg-config --cflags

[Rob Frohne]

Here is the output from pkg-config:

frohro@frohro-D610:/usr/include/jack$ pkg-config --cflags --libs jack
 -ljack -lpthread -lrt

Note that there are no include files included and when I do

frohro@frohro-D610:/usr/include/jack$ pkg-config --cflags jack

frohro@frohro-D610:/usr/include/jack$

I get a blank line. However I have a directory /usr/include/jack/ which has the following files:

frohro@frohro-D610:/usr/include/jack$ ls /usr/include/jack
intclient.h jack.h midiport.h ringbuffer.h statistics.h thread.h timestamps.h transport.h types.h

The file /usr/lib/pkgconfig/jack.pc contains the following.

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: jack
Description: the Jack Audio Connection Kit: a low-latency synchronous callback-based media server
Version: 0.118.0
Libs: -L${libdir} -ljack -lpthread -lrt
Cflags: -I${includedir}

Aha! You need to make the includedir=${prefix}/include/jack in the jack.pc file.

Thanks,

Rob

pkg-config does not output "-I<dir>" for directories that are already in the include search path

[Rob Frohne (frohro)]

Interesting. The original problem I had on this was Anjuta would not parse the symbols in jack. I asked on that list about what I needed to do and it became evident that Anjuta uses pkg-config to locate headers to locate the headers to parse symbols, and it throws an error if there is no output from pkg-config --cflags. So perhaps this bug should be tossed back to the Anjuta folks, if pkg-config should ignore headers in the include path, or perhaps it would be nice to have an option that would allow pkg-config to tell other programs where the header files are.

Also, only about half of all the packages I tested are conforming to this: For example:

frohro@frohro-D610:~/Projects/demorse$ pkg-config --cflags NetworkManager
-I/usr/include/NetworkManager

Best regards,

Rob
