Error when compile create_omi

Hi everybody
I tried to compile create_omi on my laptop (Ubuntu 16.04 x64) but I got the following error message:

/home/hdong/CMAQv5.3/lib/x86_64/gcc/ioapi/lib/libioapi.a(m3msg2.o): In function m3msg2_ ': m3msg2.F :(. text + 0x1e): undefined reference to GOMP_critical_name_start ’

Although I have successfully compiled and run other programs such as icon, bcon, mcip, jproc.
Specific of this error in the attached file.

Please show me another way to fix this error.
I appreciate the help of everyone.

You need to add -fopenmp to your compile- and link-flags.

Thanks a lot.
I added -fopenmp to FSTD and F_FLAGS, when the compilation still got the same error but when your suggestion was successful, the compilation was successful.
