Cannot build ffms2 as a shared library #281

Closed djnotes closed 6 years ago

djnotes commented 7 years ago

I am building ffms2 on Fedora 25 (x86_64). After I installed libav dependencies for the ffms2 configure file, it now complains that it cannot build ffms2 as a shared library: 

configure: error: in `/home/john/src/ffms2':
configure: error: cannot build ffms2 as a shared library
See `config.log' for more detail

Here is the complete output. I don't understand what it means and what I should do. I tried using --enable-shared flag for configure, but still with no success and received the same error.

Same issue here and also i use --enable-pic when i configured ffmpeg. I don't understand how to fix this as well. I am using the last commit ca5ef92169c43883533c95eae60981155c22979e which build passed.

We need a cop of your config.log in order to see what's going on. Can you attach it?

@dwbuiten here is my config.log output: http://pastebin.com/ep3nkbsp, I hope it helps

Are you sure you configured libav with either --enable-pic or --extra-cflags="-fPIC"? If yes, have you tried building it as a shared library instead of a static one?
