I'm trying to install pymedia in ubuntu to run scripts using python 2.7. So, I tracked down the dependencies and got them installed :

sudo apt-get install python-dev libogg-dev libvorbis-dev liblame-dev libfaad2-dev libasound2-dev python-pygame libmp3lame-dev libevent-dev

So, when I was done installing the above, during the next step which was to build pymedia, I got the following :

Using UNIX configuration...

OGG          : not found
VORBIS       : not found
FAAD         : not found
MP3LAME      : not found
VORBISENC    : not found
ALSA         : not found

As, it can be seen from the prints, the packages (in spite of getting installed properly), are mentioned as 'not found'. And the bottom line of error looks like a gcc error to me. It will be really helpful if someone could point out what could be going wrong here.

Many, many people have this problem - it's most likely due to a messed up script.

Apparently 64 bit shared libraries must be compiled with the -fPIC flag and sound.cpp isn't in this case.

In setup.py there is a function called disable_fPIC() - you can disable the function by simply replacing all the code that belongs to it with statement pass. So:

def disable_fPIC():
  pass
  • Just tried your suggestion out. It still didn't build. The prints look a bit different this time. The bottom-most line says "error: command 'x86_64-linux-gnu-gcc' failed with exit status 1". Can you make out what this means? – skrowten_hermit Oct 14 '15 at 12:30
  • @skrowten_hermit are you using 64 bit CPU? – TellMeWhy Oct 14 '15 at 14:38
  • Yes, I am using a 64-bit CPU and running 64-bit OS too. – skrowten_hermit Oct 15 '15 at 5:44
