Subject: Re: unresolved reference __ctype_b

Fred,

I encountered the same problem when I installed RHEL 3.0 and
then tried to rebuild my software.

The compat libs resolve the problem for statically linked libraries,
but not the dynamic libraries. I had some shared 3rd party libraries
built
on RH 7.x that caused the build to fail with "unresolved reference 
__ctype_b" errors.

There are some work arounds which involve creating an object or define
that resolves the "unresolved reference __ctype_b" errors, but that 
introduces
problems that were prevented by removing __ctype_b in RHEL 3.0.

The software I was building was for commercial distribution and I
couldn't
risk introducing those kinds of problems so I dropped back to RHEL 2.1
until such time as all the 3rd party libraries are available for RHEL
3.0.
