Unable to build

[Rio]

First thanks for doing this, i've been looking around for something
like this for a long time!

I've been trying to get it to work for a week now with different
methods.
I'd like to build it in a seperate environment as i'm on my
workstation and it has to be stable at all times. Here is what i've
done so far:

made a virtual environment with virtualenv.
installed cython through pip in there.
did a git checkout of ffmpeg for the 2.2 alpha of pyffmpeg
(git-35d7d6f)
build it and installed it in my virtual environment.
grabbed the pyffmpeg 2.2alpha package.
extrackted it and edited the setup.py to point to ffmpeg in the
virtual environment.
ran virtualenv/bin/python setup.py install.

and it fails everytime on all versions of ffmpeg and pyffmpeg i throw
at it.
I really hope you can help me.
I'm on debian squeeze 64 bit.
here is the build log:

hi, Rio

I think there are too many compiler options.

I have a Gentoo Linux system for x64, now build pyffmpeg-2.2 alpha and
the ffmpeg and successed.

here it is all log for pyffmpeg:

Hi Rio, 

Thanks for the message.

Thanks Kato for your contributions too, for your answer too. 

However, from my understanding, the error message is quite explicit : 

You are trying to build a dynamic library(the pyffmpeg module is a dynamic loading library for python)

 based on a static version of FFMPEG... However, this static version of FFMPEG has not

been built with the option "-fPIC" and this option is mandatory on 64 bits to create dynamicly loadable

code. 

Thus you need to install the dynamic versions of ffmpeg in order to be able to compile 

pyffmpeg.  Once you will have done so you will have ".so" files like libavcodec.so,

and then pyffmpeg will compile fine.

Let us know if this solves your problem.

Bertrand

Thanks for the tip!

Maybe you should be putting this stuff in the readme?
would be helping guys like me out a lot :)

I'll be writing some stuff with it so expect some more questions from
me!
