Hi,

Please edit your config\_cmaq.csh to use the following setting under the following section of the script:  
#\> gfortran compiler…

case gcc

setenv myLINK\_FLAG -fopenmp

Then rerun the bldit script.

Or, you can go to the BLD\* directory and edit the Makefile to use the following setting:

LINK\_FLAGS = -fopenmp

Liz
