If you want to stick with Redhat 6.0, you'll need to upgrade to IDL 5.2,
which you can download from ftp://ftp.rsinc.com/pub/idl/unix/

To get IDL 5.2 to work under Redhat 6.0, a patch is required. The
instructions below were posted by Olivier Archer
(mailto:oarcher@ifremer.fr), and have been used here successfully for
two different Linux systems.

Here's another way to get around the problem.
The goal is to define the setfpucw function

__setpucw.c:
                       
void __setfpucw(void)
{
}
void __libc_init(void)
{
}
void _dl_symbol_value()
{
}
                       
Compile it:
#gcc -fPIC -c __setfpucw.c 
#ld -shared -o __setfpucw.so -assert pure-text __setfpucw.o 
                       
define the LD_PRELOAD environnement variable before launching
idl:                       
#export LD_PRELOAD=/?/?/__setfpucw.so

Cheers,
