[Nek5000-users] compilation problems with IBM xlc compiler

Sat Mar 3 06:44:50 CST 2012

Hi again,

I just found out the problem! Actually in /usr/include/sys/types.h on the SP6 machine I am using there is a type names unique_id already defined, that was used instead of the one defined in gs.c when compiling nek5000. For the moment I just changed the name in gs.c from unique_id to unique_id2 because I don't know how to override the definition in the type.h file. Now I only have a final link problem with the function .flush:

ld: 0711-317 ERROR: Undefined symbol: .flush

I think this is easier to be solved and I will try to do so. Any suggestion?

I take the occasion to thank all of you for having shared this great tool, nek5000, with the scientific community!!

Regards,

Simone
