Gcc and C/aC++ co-existing on HP-UX Itanium system

Our company developed applications on an HP-UX 11 Itanium system using gcc.
We did not have HP's C/aC++ system installed.

We are now attempting to install/run on a customer system that already has C/aC++ on it.

Can gcc (gcc-4.3.2, or just the runtime libraries gcclib-4.3.2) be installed and used (libstdc++.so) and co-exist with HP C/aC++?

Thanks,
Bruce North

If file names collide, you may need to install in different directories, e.g. libraries in /lib, /usr/lib, /usr/local/lib, etc. Pathing and parameters must direct each compiler to its files. There is nothing like a limit on how many compilers you install. Just keep hands off any compiler used to recompile the kernel for some system parameter changes.
