[cam-users] CAM IRIX compile problem

[David Neckels]

There have been two instances of problems building the CAM on SGI 
machines.  This problem is being addressed and appears to be an issue 
with a specific version of IRIX.  It is suspected that a problem in
either remote filesystems or the ar utility is responsible.  More 
information will be forthcoming when this is resolved.

The following lists the symptoms of this problem:

1) The CCSM (CAM) compile gets to the ESMF build.  It begins traversing
the makefiles and builds ESMC_BasicUtil.o, the first file in the ESMF
build.

2) The archive facility is called to add this object file to the library
libesmf.a.  Since the library is not yet created (this is the first object
file) ar creates the library.

3) This new library has a future date (2010-02-22, 8 years in the future
in the two cases seen so far).

4) Dependency checking thereafter does not work since the library has a
future date.  None of the esmf files are built, and the build eventually
crashes when these files are needed.

I am working with SGI support and the first user who reported 
the problem to identify the specific circumstances under which the
problem occurs.

Problem reports can be filed on the ESMF website at:
http://www.esmf.ucar.edu, under User Documentation and Links. Mail is
forwarded to the appropriate staff upon submission of a problem report.  
For immediate assistance please write to esmf@ucar.edu.
