Okay - I should scour all help links more carefully. The link http://fenicsproject.org/pipermail/fenics-support/2015-June/001560.html
appears to have some suggestions to go with until I fail again. Cheers, EC From: [email protected] [mailto:[email protected]] On Behalf Of Carlson, Eric Sent: Tuesday, June 09, 2015 12:23 PM To: [email protected] Subject: [FEniCS-support] gcc version help Hello, First, let me thank all for coming up with the fenics-install.sh script. Using the script, I can successfully build the entire fenics dependency chain on Centos 7. On my Centos 6.5-based cluster, however, I can only make it up to everything through Dolfin (70+ successful package builds through pyparsing). The Dolfin build crashes due to a too-old version of gcc. Try as I might with paths and aliases, the fenics script seems to find the system gcc-4.4.7 instead of the newer gcc-4.8.2 that I've installed in /opt/gcc-4.8.2. I've set my PATH, LD_LIBRARY_PATH variables to point to /opt/gcc-4.8.2 versions first, and have aliases for gcc, g++, cc, c++, cpp, ld. Invoking builds directly in my shell seems to use the new versions fine. On the other hand, the fenics-install script seems to override/bypass all these changes. I would welcome any suggestions on the correct mods to make to get the environment to use the new compiler. Cheers, Eric
