[Wrf-users] Re: Compiling WRFV3 on i686 - module_dm.o fails

[Steven G Decker]

John,

Since it is a gfortran internal error, the compiler is to blame for your 
problem.  (This does not absolve the WRF code from having a problem as 
well, but that is impossible to tell from the information below.)

Since gfortran is now up to version 4.3.2 (or 4.4.0 if you are 
adventurous), I'd try upgrading the compiler.  That may solve the problem.

Regarding the Mac issue, I have no personal experience, but I've heard 
that upgrading/maintaining compiler tools on Macs can be notoriously 
fussy.  Does a simple test program work?

Cheers,
Steve
