In the past, we’ve gotten errors from Cadence software about an incorrectly built binary, but the program would still run ok. The annoying errors were lost by editing /etc/csh.cshrc and adding the line:
setenv LD_ASSUME_KERNEL 2.4.1 # Gets rid of the "Incorrectly built binary" error
However, after the last software upgrade, any simple unix command was giving errors about libc.so.6: cannot open shared object file. These errors weren’t just annoying, they wouldn’t allow the simple programs, like hostname, who, etc. to run. So, the LD_ASSUME_KERNEL variable had to be unset.
On our server, I then got this error:
[maryh@server maryh]$ /net/sw/cad.rh/ic/ic5141/tools/dfII/bin/32bit/icms.exe: error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory
This was solved by running:
[root@server ~]# yum install xorg-x11-deprecated-libs
Now things work ok on the server, but as the csh.cshrc file gets pushed out to the other clients, it will have to be modified to put the LD_ASSUME_KERNEL line back in. This is because the clients are running rhel4 (the server is rhel5) and they need that line.
