Compilation problems in Linux

[canavarm]

Hi, I'm compiling a FORTRAN code, and I receive an error:

(output cut)...
scale.f: In block-data unit `si':
scale.f:320: warning:
Common /Opal/llt,llr,llx,mllx,xx_op,yco,tknx,
^
Initialization of large (544440-unit) aggregate area `opal' at (^) slow and take
s lots of memory during g77 compile
make: *** [scale] Error 1


I introduced some modifications on the main program, but the program where the line appears hasn't been modified. I restored the main one to its original form, but I can't get rid of the message. What is the meaning of this error?

I use Red Hat 8, and gcc.

Thanks

1) Is there anything else called opal?
2) Are any of the variables in opal declared as huge arrays?

An easy way to track down the culprit is to separate them

      common /opal1/llt
      common /opal2/llr
      ... etc

This is a bit of a guess...

You could try putting -N in the LDFLAGS section of your makefile. This lets the various memory 'sections' overspill into one another and allows more memory to be allocated as and when it is required.
