RedHat Compatibility

[Rainer Dorsch <rainer.dorsch@informatik.uni-stuttgart.de>]

Hello,

I just want to point out a problem, you are faced with when running Debian in 
a commercial environment.

Debian needs to be redhat binary compatible.

In the meantime many software vendors support Linux and they usually support 
RedHat (often version 6.2). With Debian you run into problems like the 
following:

rainer@rax2$ ./bla
syswidth: error in loading shared libraries:
libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or
directory
TUIgui: error in loading shared libraries: libstdc++-libc6.1-1.so.2: cannot
open shared object file: No such file or directory
rainer@rax2:$ ldd /cad/bin/syswidth

rainer@rax2:$ ls /usr/lib/libstdc++-*

rainer@rax2:/cad/tbench/2001.3/bin$

I added a link and got

rainer@rax2:$ su -

It is really bad, that such a minor version number incompatibility in the 
libc creates such difficulties (more likely it is not the version number 
incompatibility).

Thanks, Rainer.
