Summary0001965: impossible to build kdenlive trunk with latest cmake 2.8.3 ?
DescriptionI am playing around building packages for the next Ubuntu release on april and I am facing this error at the end of kdenlive compilation :

Linking CXX executable kdenlive
/usr/bin/ld: CMakeFiles/kdenlive.dir/blackmagic/include/DeckLinkAPIDispatch.o: undefined reference to symbol 'pthread_once@@GLIBC_2.0'
/usr/bin/ld: note: 'pthread_once@@GLIBC_2.0' is defined in DSO /lib/libpthread.so.0 so try adding it to the linker command line
/lib/libpthread.so.0: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[3]: *** [src/cmake_bindir/kdenlive] Error 1
Additional InformationNote that kdenlive latest trunk builds fine with three previous versions of Ubuntu Linux.

After some quick tests I found that my package builds fine against cmake 2.8.2 but fails with cmake 2.8.3.

 I am misunderstanding the problem, sorry for disturbing.

But I don't understand why this happens.

 Maybe you need the pthread-dev package if there is such a thing.

 It seems that is related to a Debian change in a way it prevents the automatic resolution of symbols in indirect dependent shared libraries.

I will try to add :

find_package(PTHREAD)

in the CMakeLists.txt file

 Found the solution. To build with success I had to declare an explicit target link to pthread.
