I have two different libraries - one compiled with GCC and another with
a different, old compiler in Unix environment. Both these have C++
classes defined in them. When I link these libraries to an application
program that I created, I get a link error. This is because the name
mangling scheme used by GCC is different from that used by the other
compiler. Is there any option available to set the name mangling scheme/
not enable the name mangling?
Thanks

There's a lot that different besides name mangling. Libraries compiled
by different C++ compilers can't be used together unless the compilers
both follow the same C++ ABI, and until recently there hasn't even been
a formal ABI for C++.
See http://gcc.gnu.org/onlinedocs/gcc/Compatibility.html#Compatibility
(part of the GCC Manual) for more information about this topic.
