[mesa-users] Troubleshooting MESA

[Robert Farmer]

HI
Please keep replies on list to help others

Please follow:
http://www.astro.wisc.edu/~townsend/static.php?ref=mesasdk#Installation

to initialize the SDK, note you'll need to do this every time to load a new
terminal unless you put the commands in one of your startup scripts. Once
you've initialized the SDK do a ./clean then ./mk in the MESA_DIR.
