Have you installed glibc.i686?


Genius, very good. That seems to be the cause. Plus a couple of others, 
eg libstdc++.i686.

Thank you very much



Thanks,

Yes that was what I was about to suggest to. The:

/home/roger/pvcs/vm/linux/bin/mlcproxy: No such file or directory

Error means that the loader/dynamic-linker for the executable is
missing, which likely is /lib/ld-linux.so.2 which is part of glibc.i686 .

Recent Fedora-s no longer have any 32 bit support as part of
the default install (for 64 bit binaries, the loader is
/lib64/ld-linux-x86-64.so.2 instead).

Regards,

Hans

Could you answer the above. Without some more information about what is
seen on the disk, there isn't going to be much anyone can do to help.

I would check to see if there is an security issue as it saying `bash:

either means its not there, or something going on.

It's there, and when copied to a CentOS7 machine runs fine.

F36 pvcs problem

[Roger Wells]

we use pvcs here for CM and have for many years (~30).
Currently we are using it on RHEL 7 & Fedora.
On F35 (and earlier) no issues at all.
On F36 (installed end of last week) some programs are not recognized and 
issue error message "not a dynamic executable" when examined with "ldd":

any ideas?
