[theora] ogg movie out of png pics

[All Pebre]

Hi,

seemingly the latest theora package is not yet in the ubuntu
repository, so that I downloaded it (libtheora-1.0alpha7.tar.bz2) and
compiled correctly. The problem is that encoder_example is not
created. I see in the directory examples the c file,
encoder_example.c, but no object file; therefore I tried to compile it
but...

 gcc -o encoder_example encoder_example.c
