Re: [Discuss-gnuradio] Problem with cmake not finding includes

No only things from my new install, I deleted everything Gnuradio in /usr/lib/pkgconfig and reinstalled them.

I did notice something strange though, /usr/lib/pkgconfig/gnuradio-runtime.pc contains:

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

Name: DRI2Proto
Description: DRI2 extension headers

Version: 2.8
Cflags: -I${includedir}

And when I do the following I get:

address@hidden:~$ pkg-config --modversion gnuradio-runtime
3.7.1git

address@hidden:~$ pkg-config --libs gnuradio-runtime
-lgnuradio-runtime -lgnuradio-pmt
address@hidden:~$ pkg-config --cflags gnuradio-runtime

address@hidden:~$

As you can see --cflags returns nothing, it does this now for all packages on my system, I think this might be a pkg-config bug?

Does
find /usr/lib*/pkgconfig /usr/local/lib*/pkgconfig /lib*/pkgconfig -iname 'gnuradio*pc'
yield anything that does not belong to your current installation?

OK, rebuild and reinstalled Gnuradio after revoking that commit, then build a new module with modtool and still had the same problem:

Could NOT find GNURADIO_RUNTIME (missing: GNURADIO_RUNTIME_INCLUDE_DIRS)

checking for module 'cppunit'

Found CPPUNIT: /usr/lib/libcppunit.so;dl

It looks like it finds gnuradio-runtime, but not the headers...

Hi,

As I said in my original email, I'm using gnuradio-dev version 3.7.0-5.

As I also state in my original email, top_block.h exists in
/usr/include/gnuradio. (There are also a whole bunch of other includes
& dirs in there as well).

It isn't clear to me at the moment what are the git commits which have
been merged into the debian package. Looking at the changelog I see
this:

gnuradio (3.7.0-4) experimental; urgency=low

* Include upstream maint branch fixes - but not
Applying-hidapi-patch-from-Hans-de-Goede
- conflicts with Debian BSD kernel patches

-- A. Maitland Bottoms <address@hidden> Sun, 11 Aug 2013 18:11:24 -0400

So it obviously is the official 3.7.0 package + additional fixes - but
the actual commits are stated which makes it difficult for me to
isolate the problem commit. Hopefully Andrew will have more luck!

Thanks,

Matt
