linking with vendor provided object files

[haithcoc at gdls dot com]

I am attempting to switch to the g++ compiler from the native SGI (IRIX)
compiler.
We use n32 abi, mips 4.
I use g++ to compile, ar to archive, and g++ to link.

My link command is as follows:

g++ -g -Lang:std -L<libpath1> ... -L<libpathn> -l<lib> ...-l<libn> -o
<exec_filename>

The problem that I am having is that some of the libraries are from outside
sources (performer, etc), and the name mangling is not the same as the
native compiler, so it is not finding a match.  It results in "ld32: ERROR:
33:  Unresolved text symbol".
I can link fine on the native compiler.
Compiling all of my libraries seemed to go fine - no warnings or errors,
but I can not rebuild the other libraries with gcc, and thus cannot link.

The mangled names for the same method are different from the native
compiler and gcc (I ran c++filt).  Is there anyway to resolve the mangled
name differences problem?

Thanks in advance for any help,
Stephen
