[MITgcm-support] problem with PGI compilers

[Abbas Dorostkar]

Dear all,

I compiled the MITgcm code on a Linux Opteron cluster that uses PGI
compilers. According to the following message, it can't call simple C
routine. It would be nice if I could have your ideas. I have attached the
Opt file I used.

===  Checking system libraries  ===
  Do we have the system() command using /opt/hpmpi/bin/mpif77...  yes
  Do we have the fdate() command using /opt/hpmpi/bin/mpif77...  yes
  Do we have the etime() command using /opt/hpmpi/bin/mpif77...  yes
 * Can we call simple C routines (here, "cloc()") using
/opt/hpmpi/bin/mpif77...  no
*  Can we unlimit the stack size using /opt/hpmpi/bin/mpif77...  yes
  Can we register a signal handler using /opt/hpmpi/bin/mpif77...  yes
  Can we use stat() through C calls...  yes
  Can we create NetCDF-enabled binaries...  yes
