FCM build system - frequently asked questions

Q. How do I change where FCM builds the library archive (.a) file before the link stage?

A. FCM queries the TMPDIR environment variable. If set it uses that location, otherwise it defaults to /tmp. On HPC systems, /tmp may not be the best choice if it is in memory.

Q. What does the $HERE variable in FCM configuration files mean?

A. The $HERE variable is a special variable that FCM interprets as the directory in which the configuration file resides.
