It's okay to use gcc or g++ with ifort, so long as ifort is used to link things. But sometimes you may want the entire Intel suite to be used, so you may want to set the CC and CXX variables in your modulefile also.<br><br>Tim<br><br><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;"><b>From: </b>"Eli Ateljevich" <eli@water.ca.gov><br><b>To: </b>"tim gallagher" <tim.gallagher@gatech.edu><br><b>Cc: </b>"CMake List" <cmake@cmake.org><br><b>Sent: </b>Monday, July 2, 2012 6:09:59 PM<br><b>Subject: </b>RE: [CMake] cmake 2.6 and 2.8 find different fortran compilers with MPI?<br><br><style><!--
