[mesa-users] Fatal Error: Wrong module version for star_lib.mod

[Josiah Schwab]

> After my first successful runs with MESA after downloading it last week I felt brave enough to try the test_suite:  "binary_rlo".     When compiling it I get an error message  -- Wrong module version '7' (expected '4') for file 'star_lib.mod' -- (See below for full output).  It seems to be three versions behind.  I guess no one has tried this in a while.

Module files generated by one version of a compiler are not compatible with another version of the compiler. Somewhere along the line, the version of the compiler you're using changed. 

See for example the MESA SDK FAQ at
http://www.astro.wisc.edu/~townsend/static.php?ref=mesasdk#toc-General_Issues

What happens if you issue a ./clean command and recompile?

Best,
Josiah
