Hi Ramu,

We don't have access to any Fedora 11 systems here so what I say below might 
not be quite right, but we suspect that you're missing an RPM and that the 
error you're getting isn't an EPICS issue as such.

However I would advise you that Base R3.14.9 built for a 64-bit machine should 
*only* be used for Channel Access clients (and be aware that some of the 
standard clients like StripTool and ALH may not work on 64-bit at all yet); 
the IOC code was not properly patched to work on 64-bit until R3.14.10.

Does your /usr/lib/gcc/x86_64-redhat-linux/4.4.1/ directory contain any files 
or soft links with names starting "libstdc++.so"?  If soft-links, where do 
they point to?  You can run these commands (replacing my 4.1.1 with 4.4.1 and 
adjust the number after the .so as necessary) and compare their output to 
mine:

tux% file /usr/lib/gcc/x86_64-redhat-linux/4.1.1/libstdc++.so
/usr/lib/gcc/x86_64-redhat-linux/4.1.1/libstdc++.so: symbolic link to 
`../../../../lib64/libstdc++.so.6.0.8'
tux% file /usr/lib64/libstdc++.so.6.0.8
/usr/lib64/libstdc++.so.6.0.8: ELF 64-bit LSB shared object, AMD x86-64, 
version 1 (SYSV), stripped

My machine tux is a RHEL5 64-bit system and has two separate RPMs which are 
relevant to this issue:

tux% rpm -qf /usr/lib/gcc/x86_64-redhat-linux/4.1.1/libstdc++.so
gcc-c++-4.1.2-46.el5
tux% rpm -qf /usr/lib64/libstdc++.so.6.0.8
libstdc++-4.1.2-46.el5

I suspect you are missing the .so file completely, in which case you'll need 
to install the FC11 versions of one or more of the above packages.
