Re: Issue: TORCS won't link libpng on Ubuntu 13.10

Hi Tom

This looks good:

> LIBRARY_PATH=/usr/lib/gcc/x86_64-linux-gnu/4.8/:/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/:/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib/:/lib/x86_64-linux-gnu/:/lib/../lib/:/usr/lib/x86_64-linux-gnu/:/usr/lib/../lib/:/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../:/lib/:/usr/lib/

But this is suspect:
1.
./lib/x86_64-linux-gnu/libpng.a
I do not have this on my system, what does nm on this file say (without 
the "-D" option this time, because it is a static library), maybe it 
tries to link with the static version (your output does not indicate 
this, but check it anyway).

2. The libpng here seems to be in /lib/..., where the former one was in 
/usr/lib, could you check if this is the same file (symbolic/hard link?)
Does the file in lib has the symbol as well (check this as well with 
nm)? Which packages do these files belong to, are these in the same one?

Kind regards

Bernhard
