linker problem using gcc on osx

[Amos Anderson <amosa at caltech dot edu>]

hello -- so yesterday i worked on getting the ATLAS math library from 
sourceforge to compile on my G4 laptop with OSX. none of the 3 apple 
bundled gcc's would work, so i downloaded a fresh version from gnu, 
which i compiled and installed. i was finally able to get ATLAS 
compiled, but now i'm having problems getting my other source code 
(c++) to compile. i think the ATLAS library compiled 100% correctly, 
but i can't test it with my code...

the problem:
it doesn't matter which of 4 compilers i use, when it is trying to link 
the object files, the ld command gives many errors (undefined symbols) 
- a different number depending on which compiler i tried. the errors 
look to me like they're c++ related, a lot of them are from std::

the apple compilers worked just fine before.
when i compiled gcc 3.4.3, i used the following configuration:
Configured with: ../gcc-3.4.3/configure --program-suffix=-3.4.3 
--enable-languages=c,c++,f77,java
then, when i installed the gcc, i simply did the "make install" command 
recommended, which put all the stuff in my /usr/local directory.

so i've never compiled a compiler before, or monkeyed around with 
already installed compilers, etc. what might i have done wrong? i've 
probably made a simple mistake somewhere --
why wouldn't my compiler be able to find c++ symbols?


thanks!

Amos.
