recompile with -fPIC error.

[anil_jangam]

Hi,

I am trying to compile the vlc code based using the build procedure explained here.

https://wiki.videolan.org/UnixCompile/

After following the "Contrib method" for third party libraries, I am facing the following compilation error. I tried recompile after I compiled the FFmpeg module by assing -fPIC CFLAG option in the corresponding modules Makefile, but it did not help.

Erro rmessage is:

Code: Select all

Can someone please comment/help as to what is missing here? I am stuck and need to get this through.

Does it asking to recompile the dependent library (libavcodec.a) with -fPIC or it is asking to build vlc with -fPIC? Note that "Contrib method" as provided in the build page, builds all dependencies in satic form.

Thanks

This was resolved after compiling on Ubuntu 12.04 fresh install. I was using 14.04 and perhaps the repo was culprit.
