RE: glibc-2.7 and gcc-4.2.2 install on redhat 3 u 9 - x86_64

[Lamont, Brian-p3354c]

This install appeared to complete successfully, however, compiling a simple 
"hello world" doesn't produce any output.   The engineer testing his source 
code is getting errors and I've asked for them, and will send upon receiving 
them.  I did NOT set env CC=cc (syntax ??).  The readme talks of settings the 
CC variable.  Will not doing this allow a successful configure, but bad 
compilation?

Are there any special configure options building gcc on redhat linux?  
Comparing mine with a  Redhat 4 system below.  I've been browsing through the 
options but really unsure if any of them are needed, but some do raise concern.


This is the configure from the problem system -- redhat 3 updt 9.
-----------------------------------------------------------------
<sys-root> gcc -v

This gcc is from the Redhat 4 system used as comparison

OK, make sure that the --prefix=... dir. does not point into the source tree. I 
usually use /usr/local/gcc-4.2.2.

good luck,
