gst-plugins-bad-1.8.3 can't see cuda-7.5

[llama]

Hello!

I am trying to get nvenc of bad plugin set, but in order to get this, i have to setup cuda so that gstreamer can find it.

My current setup is:
ubuntu 16.04,
Gstreamer 1.8.3,
cuda-7.5 (as a .deb pkg),
nvidia driver 367.44
pkg_config_path: /usr/local/lib/x86_64-linux-gnu/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig.

After .configure it reports: *** Plug-ins with dependencies that will NOT be built: nvenc, ...
In config.log : Package cudart-7.5 was not found in the pkg-config search path.
Perhaps you should add the directory containing `cudart-7.5.pc'
to the PKG_CONFIG_PATH environment variable
No package 'cudart-7.5' found.

So i did set on PKG_CONFIG_PATH to see /usr/local/cuda-7.5/pkgconfig/. But no result. The same scenario on cuda.8-0 and the same fail. With 8.0 is even worse because configure.ac does not include cuda-8.0 in PKG_CHECK_MODULES.

Any help, please. I have no more ideas. What can I do or  check, or setup or test ?

Thanks!

1. Make sure that cudart-7.5.pc is in a directory in PKG_CONFIG_PATH
2. Make sure the contents of that file point to where the actual
libraries/headers are.  The packages from nvidia contain the original
build directory paths which will never work when installed on a system.
3. Optionally, there's the --with-cuda-prefix argument which will check
for the libraries/headers manually.
4. If all else fails, You can override CUDA_CFLAGS and CUDA_LIBS
manually.  This should only be a last resort.

You can check
https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/configure.ac#n1901
for the logic of what's used when.

Thanks!

After setting cudart-7.5.pc and cuda7.5.cp is in a directory in PKG_CONFIG_PATH and by  ./configure --with-cuda-prefix=/usr/local/cuda-7.5 I get one step further, but than nvenc complains about -lnvidia-encode. That it can't find it. So I created /etc/ld.so.conf/ new x.conf for /usr/lib32/nvidia-367/ path to find this :

libnvidia-encode.so (libc6) => /usr/lib32/nvidia-367/libnvidia-encode.so

After .configure still cant find libnvidia-encode.so. Ok, i created ln -s in /usr/local/lib/ with libnvidia-encode.so file. And than after  ./configure --with-cuda-prefix=/usr/local/cuda-7.5 it says:  

: gcc -o conftest -g -O2   conftest.c -lnvidia-encode    >&5
/usr/bin/ld: skipping incompatible //usr/local/lib/libnvidia-encode.so when searching for -lnvidia-encode
/usr/bin/ld: cannot find -lnvidia-encode

Why it's going to skip it. So what is wrong with that file or compiler or anything else ?
Is there anyone having the same bad experience to setup envenc plugin ?

Thanks for any advice !

Already solved!
32bit lib version specified to link it.
