Here is my summary of responses. The first response from Casper Dik is
the one that worked. Apparently there are hard coded paths in the compiler,
so setting a couple of links fixed things. I set one for the lib/gcc-lib
and one for the /opt/GCC27271 and all is well.

thanks,

Make a link from /opt/GCC2721 to /opt/software/opt/GCC2721

or set GCC_EXEC_PREFIX

Hi Chuck,

my experience with the packages on the net is that they truly
expect to be in the original place there were installed. So,
this gcc packages actually expects to be /opt/GCC2721/blah.
This is the reason it cannot find cpp, which it expects to be in
/opt/GCC2721/lib/gcc-lib/sparc-sun-solaris2/2.7.2.1 (probably something
like that). A link might solve the problem.
Also, adding the package again and letting it pick the default location
would probably work as well.

Hey, I haven't seen you on this list before..

cpp is in ..../lib/gcc-lib/sparc-sun-solaris2.5/2.7.2.1/cpp

...or something like that.

Anyway, it's not in bin, it's in a lib dir somewhere.

Thanks

Daniel

cpp is in /usr/ccs/lib and is part of the SUNWsprot package.

I have it in my search path.

Sorry, no solution, but it may help to know that I ran into the exact same
problem when trying to install the groff text processing package (which
requires a working c++ compiler).

Seems like the c++ compiler in the precompiled binary is broken. I have
been unable to compile a simple "hello world" c++ program using the same
compiler. I even tried using the precompiled version to compile the latest
version of gnu gcc. Still had the same problem.

Looking forward to your summary -

Joel

You can't change the install path for gcc -- paths are hard-compiled in. Well, you *can*, but you have to pass flags to gcc to make it work, meaning every time you compile you'll have to adjust makefiles, etc. I **think** you need -B/opt/software, I'm probably wrong. Check the info or man pages for gcc.

I think you probably need to install the "SUNWbtool" package off of the OS CD. That gives you all the stuff in /usr/ccs which should include cpp.
