[Wrf-users] [Solved] Re: [WRF 3.5.1, smpar, Intel] undefined reference to `__kmpc_global_thread_num' building "external/io_int"

[Бакиров, Медер]

Thank you very much, Dmitry!

The problem was with an '-openmp' flag was not including in compiler
opts. I adjusted the 'external/io_int/makefile' to include this flag:

and the problem has gone.
