Compiling FFMPEG from source: cannot find shared library

Question

I'm compiling FFMPEG from source using the guide for Ubuntu which I've used before with success.

I'm compiling on a Vagrant virtual machine in VirtualBox on Ubuntu server 14.04. You can clone the project and vagrant up, and you'll have FFMPEG installed in the box: github.com/rfkrocktk/vagrant-ffmpeg.

I'm using Ansible to automate the compilation, so you can see all of the steps here:

Hopefully, even if you don't know Ansible, it should be clear what this is doing.

The problem I'm having is that even after all of this running successfully, when I run ffmpeg from within the machine, I get the following error:

ffmpeg: error while loading shared libraries: libx265.so.77: cannot open shared object file: No such file or directory

I can clearly find the file:

$ find /usr -iname libx265.so.77
/usr/local/lib/libx265.so.77

Why is this not being found? Am I missing something in the compilation guide? I'd like my binaries to be as portable as humanly possible.

/usr/local/lib/libx265.so.77: ELF 64-bit LSB  shared object, x86-64, version 1 (GNU/Linux), dynamically linked, BuildID[sha1]=f91388281cc2dba1dfe37797324dc6b3898d8d1b, not stripped

LD_LIBRARY_PATH is undefined in environment variables.

Also this:

 $ grep -r local /etc/ld.so.conf.d/
 /etc/ld.so.conf.d/libc.conf:/usr/local/lib

~~My working theory is that because the Ansible command module strips environment variables, everything breaks.~~

I'm thinking that there's something wrong with the FFMPEG or x265 build. I removed --enable-libx265 from the FFMPEG configure command and I now have a working FFMPEG.

What is the output of ldd /usr/local/bin/ffmpeg and file /usr/local/lib/libx265.so.77? I'm skeptical that is truly a shared library or points to one since you have -DENABLED_SHARED:bool=off in your cmake command line for that library, which should leave you with .a libraries, not .so shared objects. — casey

Here it is: pastebin.com/P84ZK75V ; My goal is for all of the binaries to get as static as possible for portability. — Naftuli Kay

What is the output of file /usr/local/lib/libx265.so.77, you didn't include that above. Also post the output of echo $LD_LIBRARY_PATH and cat /etc/ld.so.conf | grep local. — casey

@casey Updated the question and tried recompiling with the Ansible shell module instead of command in order to preserve the environment and I'm getting the same problem. — Naftuli Kay

My problem lay in the fact that I never ran ldconfig after installing everything.

In order for shared object libraries to be found on Debian, you must run sudo ldconfig to rebuild the shared library cache.

This worked for me. Just running sudo ldconfig, then trying ffmpeg again worked. No recompiling needed.
