Hello,
I ran into another error building Qt5:

cp: impossibile eseguire stat di "/home/marco/dev/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/lib/libqgsttools*.so.*":
File o directory non esistente

It says it doesn't find libqgsttools*.so.*, I searched in the nconfig (using F8) and using find -name in the package directory without chance.

Which package is required?

Attached the .config file.
Thanks
Marco

Hello,
I ran into another error building Qt5:
cp: impossibile eseguire stat di "/home/marco/dev/buildroot/output/host/usr/arm-buildroot-linux-gnueabi/sysroot/usr/lib/libqgsttools*.so.*":

I created a build with your .config file, and did not have any error. libqgsttools is present in qt5multimedia itself:

output/build/qt5multimedia-5.2.1/lib/libqgsttools_p.so.1.0.0 output/build/qt5multimedia-5.2.1/lib/libqgsttools_p.so.1.0 output/build/qt5multimedia-5.2.1/lib/libqgsttools_p.so.1 output/build/qt5multimedia-5.2.1/lib/libqgsttools_p.so output/build/qt5multimedia-5.2.1/lib/libqgsttools_p.prl

Did you do something special in your buildroot directory/repo ? Try starting from a clean environment:
make clean all

Best regards,
Thomas

Hi Thomas,
I tried to:

1) git clone again buildroot, in order to have a clean environment
2) copy my .config file
3) check it with make nconfig (without change anything)
4) make

It fails in the same way and under output/build/qt5multimedia-5.2.1/lib there are no libqgsttools* files...
I can't understand why it fails only on my pc!

Thanks!
Marco

I have executed 'make qt5multimedia-dirclean qt5multimedia' now and pasted the output here:

maybe it can be useful for you to analyze the problem on your machine.

Hi Thomas,
here my output:

http://pastebin.com/4QkcJ97t

it seems it doesn't find gstreamer:

Checking for openal... no
Checking for alsa... yes
Checking for pulseaudio... no
Checking for gstreamer... no
Checking for resourcepolicy... no

It's strange because it's already built.
What might lead to different behaviors among different machines with the same buildroot clone and .config file?

Best regards
Marco

What's the name of the gstreamer-0.10 development package in buildroot? I can't find anything in nconfig or in the package dir.

The package is built in output/build/gstreamer-0.10.36 and the .mk file is in package/gstreamer/gstreamer/gstreamer.mk

This package is pulled in by qt5multimedia as follows:

qt5multimedia:
ifeq ($(BR2_PACKAGE_GST_PLUGINS_BASE),y)
QT5MULTIMEDIA_DEPENDENCIES += gst-plugins-base
endif

gst-plugins-base:
GST_PLUGINS_BASE_DEPENDENCIES = gstreamer

As your config sets BR2_PACKAGE_GST_PLUGINS_BASE, the gstreamer package should be built.

If it's not the case: how are you building exactly, simply 'make' ?

Best regards,
Thomas

It seems all correct here. The gstreamer package is built, actually. I don't know if I might check something in details to be sure there were no problems here.

Yes. As said before I just did:

1) git clone git://git.buildroot.net/buildroot
2) cd buildroot
3) cp /path/to/.config .
4) make nconfig, without any changes, F9
5) make

That's it.
Best regards

You can go to output/build/qt5multimedia and try to re-execute the command mentioned in config.log related to the gstreamer test. Maybe you can debug based on that, maybe using 'strace -fo /tmp/out <command>' to check what kind of files it is looking for.

I have no better ideas, sorry...

I issued:

strace -fo /tmp/out /home/marco/dev/buildroot/output/host/usr/bin/qmake "CONFIG -= qt debug_and_release app_bundle lib_bundle" /home/marco/dev/buildroot/output/build/qt5multimedia-5.2.1/config.tests/gstreamer Project ERROR: gstreamer-0.10 development package not found

Here the strace output:

http://code.bulix.org/7oi5mj-85862

I'm not so expert to understand what's happening.

Unfortunately this feature is mandatory for my project.

Are we working on the same repo? 2014.05-git-00363-g3749143 Unless buildroot needs something outside it's own directory it's very strange such a behavior.
For you information my host machine is:

Linux devrpi 3.2.0-4-686-pae #1 SMP Debian 3.2.51-1 i686 GNU/Linux

The problem is this:

3752 stat64("/usr/bin/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  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:

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!

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.
