error: undefined reference Qt 5.8 os/ Ubuntu 14.04.05

[roygbiv]

Hi all,

I am working on my first Qt project.

Specifically, I'm working with Qt 5.8 os on a host machine running Ubuntu 14.04.05.

I thought I managed to successfully configure Qt and make Qt, but reaching the make install stage I receive these error messages all do do with Gstreamer:

.obj/camerabinsession.o:camerabinsession.cpp:function valueRange(_GValue const*, bool*): error: undefined reference to '_gst_int_range_type'

Could someone please advise what I should investigate to solve this problem. Having done some background research it appears this might be a problem with the linker and shared libraries, any thoughts?

[SGaist]

Hi and welcome to devnet,

Are you missing the GStreamer library on your system ?

[roygbiv]

Hi SGaist,

Thanks for stopping by. Does it look like there are packages missing? Can you tell which ones?

I have the following Gstreamer packages installed:

1. libpulse-dev
2. libgstreamer1.0-dev
3. libgstreamer-plugins-base1.0-dev
4. ubuntu-restricted-extras
5. gst-ffmpeg-0.11.2
6. gst-plugins-base-1.10.3
7. gst-libav-1.10.3
8. gst-plugins-bad-1.12.1

1-4 were installed before make, and 5-8 were installed after make (I thought I only needed 1-4.) I will now make uninstall, and do a fresh install to see if that helps. More news tomorrow morning...

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into /qt-5-8-install

Any thoughts?

[SGaist]

You seem to have everything needed installed.

And so it only happens when you call "make install" after calling ",make" ?

[roygbiv]

Yes, it only happens when i call "make install" having called "make".

I have reconfigured the installation and done this several times now and end up with the same error.

[SGaist]

Can you show the configure line you are using ?

[roygbiv]

../qt-everywhere-opensource-src-5.8.0/configure -nomake tests -nomake examples -opengl desktop -prefix /qt-5-8-install

[SGaist]

Can you check with a more recent version of Qt ?

[ambershark]

@roygbiv So this usually happens when you compile with a newer set of gstreamer headers > 1.4 and then link to an older gstreamer 1.0 library.

It sounds to me like you have multiple gstreamer installs and Qt is attempting to use both.

What does find / -iname "gst.h" give you? Also find / -iname "libgstream*"?

[roygbiv]

Hi @ambershark

Thanks for dropping by.

I think you're onto something. How do I figure out what i don't need and uninstall it without disturbing existing dependencies? I need Gstreamer 1.0.

find / -iname "gst.h" returned:
find: ‘iname’: No such file or directory
find: ‘gst.h’: No such file or directory

find / -iname "libgstream*" returned:
find: ‘iname’: No such file or directory
find: ‘libgstream*’: No such file or directory

Does this help :

[ambershark]

@roygbiv Yea that helps... you have 6 different gstreamers installed, lol. The chance you are linking to multiples just went up by quite a bit. ;)

As for the -iname, it didn't seem to take that as a parameter to find. Which is weird since that has been in find since like ... forever. It's almost like you did find iname "gstreamer*" and missed the -iname based on the output you got. -iname is the same as -name except that it ignores case. I almost never use -name because of case issues in linux. :)

Now if I had to guess I'm betting the culprits are the /usr/lib/x86_64 one and the /usr/local/lib one. They are different versions and a lot of people add /usr/local/lib to their LD_LIBRARY_PATH or ld.so.conf.
