Compilation error multiple definition #5
Description
Hi,
I've been trying to compile snppit under linux (gcc 12.2.0) by running Compile_snppit.sh.
This failed with these errors:
src/pbt_C_fb.c: In function ‘ForwardStep’:

collect2: error: ld returned 1 exit status
My fix was to add the flag "-fcommon" to the gcc command, and it now compiles successfully. I've ran the tests, and they almost all pass.
