[physfs] Mac OS X 10.7 build problems

[Christoph Ender]

Hi,

trying to build physfs-2.02 on the new Lion release of Mac OS X results in the
following output:

It seems like removing the "-Werror" flag from "CMakeLists.txt" in line
ADD_DEFINITIONS(-g -pipe -Werror -fsigned-char) apparently makes the code
compile successfully (not tested thoroughly in any way, but libsdl-sound
which builds on top of physfs seems to work).


Regards,
Christoph.
