Problem linking

[Maxxi]

Linking C executable chipmunk_demos
/usr/lib64/gcc/x86_64-suse-linux/4.6/../../../../x86_64-suse-linux/bin/ld: ../src/libchipmunk.a(cpVect.c.o): undefined reference to symbol 'sincos@@GLIBC_2.2.5'

/lib64/libm.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[2]: *** [Demo/chipmunk_demos] Error 1
make[1]: *** [Demo/CMakeFiles/chipmunk_demos.dir/all] Error 2
make: *** [all] Error 2


Any idea how to fix this?

Like it says (very cryptically), it's not linking to the math library. Not sure why it wouldn't be by default like every other gcc setup. You'll have to add -lm to the linker options.
