[omniORB] 2.7.1 and RedHat Linux 6.0?

[Sai-Lai Lo]

Well, I've told our sysadmin to stay with RH 5.2. There are 2 issues with
RH 6.0 in relation to program development:

1. gdb on RH6.0 can no longer debug multithreaded programs (omniORB2
   programs included).

2. The libc library is glibc-2.1 which is incompatible with glibc-2.0 in RH
   5.2.

   Looks like RH has created a wrapper library so that binaries compiled on
   RH 5.2 (glibc-2.0) continues to run.

   But if you compile a program on RH 6.0 and link it with libraries
   created on RH 5.2 (glibc-2.0), the executables just core dump.
   For instance, I can't even run a simple hello world when it is compiled
   with egcs (RH 5.2 binary). I believe this is because the hello world
   executable is linked with the stdc++ shared library of egcs (RH 5.2).

   As you can see, it is a mess. You might do better if you have built
   everything from scratch on RH 6.0. 

For us, we stay with RH 5.2 until there is a clear advantage to move on to
glibc-2.1 based system.
