Sorry for the delay here - I've been on the move continuously for the last few days. Here's what I should have recommended earlier. Start by using
ldd to display the library dependencies of ashell:
[root@centos bin]# ldd ashell
libm.so.6 => /lib/tls/libm.so.6 (0x003e2000)
libncurses.so.5 => /usr/lib/libncurses.so.5 (0x0589f000)
libpcre.so.0 => /lib/libpcre.so.0 (0x00407000)
libdl.so.2 => /lib/libdl.so.2 (0x003dc000)
libc.so.6 => /lib/tls/libc.so.6 (0x002af000)
/lib/ld-linux.so.2 (0x00291000)
I suspect that on your system, you will instead see some kind of "not found" message for the libpcre entry.
Next, check the system shared library path:
[root@centos bin]# cat /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/ofed/lib
/usr/local/lib
(You may need to drill down to see the include'd files if applicable.)
Then, assuming nothing points to /lib64, despite the arguments of the well-written article you referenced in your post, as a temporary test go ahead and
export LD_LIBRARY_PATH=/lib64 and see if A-Shell will now load.
It may well be that the 64 bit version isn't compatible, but I suspect you'll get a different error message than file not found. If so, then you can download a
tar\'d copy of the libpcre.so.0.0.1 version 7.4 here ; I suggest dropping it into /lib, which is presumably part of your system default library path.
You want to end up with libpcre.so.0 linked to libpcre.so.0.0.1
