Hi,

I just downloaded, configured, compiled and installed mlt 0.5.10. Now I wanted to compile kdenlive, but what I get from cmake is:

(...)
-- Found automoc4: /usr/bin/automoc4
-- checking for module 'mlt++'
-- package 'mlt++' not found
CMake Error at /usr/share/apps/cmake/modules/FindPkgConfig.cmake:286 (message):

-- MLT install path:

CMake Error at CMakeLists.txt:21 (message):

Please install recent MLT http://www.mltframework.org


-- Configuring incomplete, errors occurred!

So on one hand it finds the files in /usr/local/include and /usr/local/lib64, but on the other hand it tells me the package was not found. How's that? And yes, the files are in place:

lrwxrwxrwx 1 root root 18 27. Sep 23:32 /usr/local/lib64/libmlt++.so -> libmlt++.so.0.5.10
-rwxr-xr-x 1 root root 184917 27. Sep 23:32 /usr/local/lib64/libmlt++.so.0.5.10
lrwxrwxrwx 1 root root 18 27. Sep 23:32 /usr/local/lib64/libmlt++.so.3 -> libmlt++.so.0.5.10

and

What do I do wrong?

Thanks for your help!

The MLT version is cached by CMake. try deleting the file CMakeCache.txt in Kdenlive build dir and run cmake again should solve your problem

Hi j-b-m,

thank you for the advice. But this doesn't work either. I also removed the complete directory with the kdenlive sources and restarted by untarring it again, to get a perfectly clean start. Same result.

Some more background info on my mlt installation: I used to work with mlt 0.5.4 and kdenlive 0.7.7, both installed via the gentoo software management (emerge from portage tree). Unfortunately, mlt 0.5.10 and kdenlive 0.7.8 are not in the portage tree yet, not even in the unstable branch. Looks like nobody has prepared an ebuild yet. (BTW: Does anyone know how to push this process?)

So I thought I could keep mlt 0.5.4 and kdenlive 0.7.7 in /usr (don't want to break my working system) and install mlt 0.5.10 and kdenlive 0.7.8 in /usr/local. Linux and especially Gentoo is meant to be able to deal with different versions. Installing mlt in /usr/local was easy, but kdenlive cmake found the 0.5.4 version in /usr first. I am not familiar with cmake, I prefer the good old configure scripts with options like --mlt-path=/usr/local. How is that done with cmake, how can I tell it that the mlt install path is /usr/local? Anyway, I uninstalled mlt 0.5.4 via the Gentoo software management, I can re-install it later if I need to. Shouldn't the output of cmake show something behind "-- MLT install path:"? I'd guess I only have to pass the right path somehow instead of relying on cmake's search capabilities. Or is my mlt install incomplete somehow?

So this situation makes it plausible that cmake cached some information about the old mlt. But as mentioned above I retried with clean, freshly-untarred kdenlive sources, same result.

I don't know if this is related, but the file CMakeError.log ends with these lines:
/usr/bin/gcc -DCHECK_FUNCTION_EXISTS=pthread_create CMakeFiles/cmTryCompileExec.dir/CheckFunctionExists.c.o -o
cmTryCompileExec -rdynamic -lpthreads
/usr/lib/gcc/x86_64-pc-linux-gnu/4.3.4/../../../../x86_64-pc-linux-gnu/bin/ld: cannot find -lpthreads
collect2: ld gab 1 als Ende-Status zurück
gmake[1]: Leaving directory `/scratch/kdenlive-0.7.8/build/CMakeFiles/CMakeTmp'
gmake[1]: *** [cmTryCompileExec] Fehler 1
gmake: *** [cmTryCompileExec/fast] Fehler 2

BTW, my kdenlive 0.7.7 installation works "almost" now (after setting the mlt-path to /usr/local), but this might be because it was compiled with mlt 0.5.4 and uses mlt 0.5.10 now.

Cheers

Sorry, sorry! My bad!
I somehow missed the option --with-gpl for the mlt configure script. And I admit I should have found this out earlier.
All the installation was fine now.
Sorry again for bothering you with that.

I'm on Fedora 13, and I'd like to try kdenlive 0.7.8 myself.
I have the same your problem but I'd like to compile and install mlt/kdenlive as user ( it means that I'd like to install the libs and package in my home).
I compiled mlt and I have installed it in /home/user/mlt-5.10 but kdenlive (same as you) finds only the 0.5.4.
What did you exactly ?
Thanks!
