Linux (Xubuntu 12.10 64 bit) build problem: conflicting types for 'ssize_t'

[evktalo]

Trying to build on Linux, I get the following errors. Environment: 64 bit Xubuntu 12.10

C-Dogs SDL cannot be compiled as 64 bit; try adding -m32 to the compiler flags; I think you can do this by adding a add_definitions(-m32) to the src/CMakeLists.txt file.

I managed to compile, but ran into incompatibility problems while linking.

I think the linker also needs the -m32 flag. Try these links to see if they help:
