[mesa-users] MESA compilation on BG/P with XL compilers

[Sean Couch]

Thanks, Bill, Josiah. 

Making the ‘ck’ scripts do nothing seems to be the trick.  The compute nodes don’t have compilers.  I’m making progress, but IBM XL compilers are cranky…  GNU isn’t really an option, either.

Thanks for the help!
Sean

But if you can't run the compiler on a compute node, then turning off the "ck" scripts during compilation will work.  If you turn off the tests during compilation, then you will of course need to run them all later on a compute node.  To do that, you could edit the "each_package_do" script to make the do_one function do the following:
