Hello:
/usr/bin/g++ -o UnitTest  -L/epics/extensions/lib/linux-x86
-L/epics/base-3.14.9 /lib/linux-x86/

I assume the space between base-3.14.9 and /lib/linux-x86
got added in the copy/paste of email creation?
-Wl,-rpath,/epics/extensions/lib/linux-x86 -Wl,-rpath,/epics/bas
e-3.14.9/lib/linux-x86/    -L/usr/local/lib -lxerces-c
...
/usr/bin/ld: warning: libstdc++.so.5, needed by
/usr/lib/gcc/i386-redhat-linux/3 .4.4/../../../libxerces-c.so, may
conflict with libstdc++.so.6
...
../FUX.cpp:230: undefined reference to `xercesc_2_4::...

I think you're seeing all the missing symbols from the xercesc
library because on one hand you correctly installed
the xercesc_2_4 from the ThirdParty subdir,
presumably under /usr/local/lib,
and compiled all the object files for that,
but on the other hand the linker command is now trying to link
some other version of xercesc that you happen to
have in /usr/lib/libxerces-c.so.
Not sure how to force the linker to look in /usr/local/lib
_before_ checking /usr/lib, but that would be what I'd try
to accomplish here.
If all else fails, move /usr/lib/libxerces-c.so temporarily
someplace else?
You could also try to use that /usr/lib/libxerces-c.so from the start,
i.e. remove the xercesc_2_4 from /usr/local/lib.
But /usr/lib/libxerces-c.so seems to have problems on its own
("libstdc++.so.5 ... conflict with libstdc++.so.6").
