Hi Robert,

I just wanted to blast you a note with the results of my tests for mapping
on top of GMS imagery under Linux using an image IMGCOPYed first to a 
Sun Solaris SPARC (big endian) system.

On Sun Solaris SPARC 5.6 system:

IMGCOPY IMGCOPY GMS/GMGLOB05I2 MYDATA/IMAGES.1234 SIZE=ALL
Beginning Image Data transfer, bytes= 4938136
Transferring AREA data outbound, bytes= 4938216
IMGCOPY: GMS/GMGLOB05I2.6 copied to MYDATA/IMAGES.1234
IMGCOPY: done

IMGDISP MYDATA/IMAGES.1234 LATLON=-23 -134 EU=IMAGE REFRESH='EG;MAP SAT'
Beginning Image Data transfer, bytes= 579624
IMGDISP: loaded frame  1
EG;MAP SAT
IMGDISP: done
EU: Restoring IMAGE.ET     to frame(s)=   1
EU: Done
Erased graphic frame(s) 1-1
MAP: Completed frame 1

On RedHat 7.1 Linux:

IMGDISP MYDATA/IMAGES.1234 LATLON=-23 -134 EU=IMAGE REFRESH='EG;MAP SAT'
IMGDISP: The requested Earth location is not contained in the image
IMGDISP: done
IMGDISP failed, RC=2

Interestingly, the IMGDISP of the exact same image does work on Solaris
x86 5.8:

IMGDISP MYDATA/IMAGES.1234 LATLON=-23 -134 EU=IMAGE REFRESH='EG;MAP SAT'
Beginning Image Data transfer, bytes= 579624
IMGDISP: loaded frame  1
EG;MAP SAT
IMGDISP: done
EU: Restoring IMAGE.ET     to frame(s)=   1
EU: Done
Erased graphic frame(s) 1-1
MAP: Completed frame 1


This confirms the problem we saw during the workshop is a Linux only
one!  The distribution of McIDAS-X I was running, v2002a, was built
using gcc/g77 on both Solaris SPARC and Linux, but it was built using
Sun compilers on x86.  So, the problem may or may not be related to
Linux.  It may be related to the version of g77 being used on our Linux
platforms.  This one scares me!

I did confirm that it works fine on our RH 7.2 box, built
with gcc/g77, I will see what version of the GNU compilers
we have.

I have a non operational Solaris Intel box as well here at Universal and
will build
it there with gcc/g77.
