Description Need Real Name 2000-11-14 16:44:03 UTC

After installing RedHat Linux 7, I began to have a very weird, and quite
detrimental problem...

Matlab 5.3 will not execute.  On running the executables I recieve all
kinds of "command not found" messages despite the fact that the file
exists.

In addition, I'm having the same problem with the Laey package of Fortran
90 compilers.

I read your previous message about libc5... however these packages run fine
under RedHat 6.2 - which as far as I was aware, do not run libc5.

As this seems to be a fairly widespread problem affecting all sorts of
software your general user may wish to install under RedHat 7 - it seems
like you ought to produce a document outlining how to fix this.

May I point out that these are the latest releases of this software.  And
it stands to reason that the new release of Linux ought to support the
newest releases of various software packages, or what's the point of
upgrading.

Let me know if you can help, otherwise I'll be unhappily downgrading to an
earlier version of linux.

It is a libc5 issue.
Red Hat Linux 6.x used glibc (libc6) by default, but had a compatibility package for old libc5 applications. We've kept a compatibility library for an obsolete and broken libc for about 2 years - that should be enough time for any serious software vendor to update.

If you need to use libc5 applications on Red Hat Linux 7, install the libc and ld.so packages from Red Hat Linux 6.x - they'll work, and provide the same backwards compatibility 6.x had.
