libx264 not found on some systems

[strycore]

I've received two reports that the script fails to build on some system with ffmpeg being unable to find libx264. Here is a detailed report of the errors below:

The error I get appears to be during the configure for ffmpeg:

2016-07-27 13:53:19 (1.72 MB/s) - ‘ffmpeg-3.1.tar.bz2’ saved [9329359/9329359]
ERROR: libx264 not found

I've looked at source/ffmpeg-3.1/config.log and determined that the x264 headers were not in place:

/tmp/ffconf.J7WYN2Vg.c:1:18: fatal error: x264.h: No such file or directory

compilation terminated.

I was able to correct this by adding "make install-lib-dev" to the x264 install after "make install" but I still have an issue finding libx264:

/usr/bin/ld: cannot find -lx264

The only file I could find that I think might match is libx264.a which does not get installed by x264's makefile. I think this might be a bug on x264's end. I added a simple cp after the "make install-lib-dev" added above and the build gets further:

cp libx264.a $build_dir/lib/

Now I get the following when building:

/usr/bin/ld: /home/redkrieg/nvenc/ffmpeg-nvenc/lib/libx264.a(common.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC

Installing the libx264-dev package is a workaround but it shouldn't be needed, we already provide it from our script

I am experiencing this issue as well. Installing libx264-dev did fix it. Also, didn't video sdk 7.0 come out?

I added the libx264-dev package as a dependency for the time being.

For the Nvidia SDK 7, I haven't managed to get a direct downloadable link to it without having to enroll to the Nvidia developer program and log in to their website.
