The problem is this:

3752  stat64("/usr/local/bin/pkg-config", 0xbf8c2860) = -1 ENOENT (No
such file or directory)
3752  stat64("/usr/bin/pkg-config", 0xbf8c2860) = -1 ENOENT (No such
file or directory)
3752  stat64("/bin/pkg-config", 0xbf8c2860) = -1 ENOENT (No such file
or directory)
3752  stat64("/usr/local/games/pkg-config", 0xbf8c2860) = -1 ENOENT
(No such file or directory)
3752  stat64("/usr/games/pkg-config", 0xbf8c2860) = -1 ENOENT (No such
file or directory)
3752  write(2, "sh: 1: ", 7)            = 7
3752  write(2, "pkg-config: not found", 21) = 21
3752  write(2, "\n", 1)                 = 1
3752  dup2(10, 2)                       = 2
3752  close(10)                         = 0
3752  exit_group(127)                   = ?
3751  <... waitpid resumed> [{WIFEXITED(s) && WEXITSTATUS(s) == 127}], 0) = 3752
3751  rt_sigaction(SIGINT, {SIG_DFL, [], 0}, NULL, 8) = 0
3751  rt_sigaction(SIGQUIT, {SIG_DFL, [], 0}, NULL, 8) = 0
3751  rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
3751  --- SIGCHLD (Child exited) @ 0 (0) ---
3751  write(2, "Project ERROR: gstreamer-0.10 de"..., 60) = 60
3751  exit_group(3)

It tries to find pkg-config, but fails to do so. pkg-config is used in
the test to try and find gstreamer.
Normally, pkg-config should come from buildroot itself
(output/host/usr/bin/pkg-config) but it seems this is not happening
here.

I did the same on my machine, and it seems /usr/bin/pkg-config is
used. This is not supposed to happen.
It explains why building the same configuration on different machines
gives different results.

This is actually a bug.
Could you try following patch:

$ hg diff

and after applying this patch run:
make qt5multimedia-dirclean qt5multimedia

I believe this should fix the problem. The same solution should be
applied to the other qt5 packages.
Or maybe someone else thinks the problem should be fixed in a different way.
I'm adding some people to this thread so they can shed their light on it...

Best regards,
Thomas

Your change indeed looks good.

I confirm it compiled successfully after applying your patch. I haven't 
tried yet QtMultimedia on the target, but at least there were no errors 
at compile-time :-)

Thank you for your support!

I'm glad to say it works!

Thank you

That's great, thanks for your feedback!
In the mean time I sent patches to the list to fix this issue for all
qt packages.

Best regards,
Thomas
