Setting up a working development environment (gcc & SunStudio 12)

Question

Hi, every time I set up a new OS / zone installation for development use I stumble upon the same problems and can't get out of it .
First, here's my path :
11:38:22|grattojf@bergen:~] echo $PATH
/opt/csw/gcc4/bin:/usr/ucb:/usr/ccs/bin:/usr/bin:/usr/sbin:/opt/csw/gnu/bin:/opt/bin:/opt/csw/bin:/usr/sfw/bin:/tools/mysql/bin:/opt/qt4/bin:/tools/SUNWspro/bin
As you can figure, I'd like to run both gcc4 (from blastwave) and SunStudio12 (downloaded, not yet installed).
Right now, I'm trying to compile Fedora Directory Server on my box and ./configure fails like this:
[11:40:49|grattojf@bergen:~/Fedora/01.nspr-4.7.4/mozilla/nsprpub] ./configure prefix=/tools/fdsTools with-mozilla disable-debug enable-64bit enable-mdupdate enable-cplus enable-strip with-pthreads

checking target system type... i386-pc-solaris2.10
checking build system type... i386-pc-solaris2.10
checking for whoami... /usr/ucb/whoami
checking for gcc... gcc
checking whether the C compiler (gcc ) works... yes
checking whether the C compiler (gcc ) is a cross-compiler... no
checking whether we are using GNU C... yes
checking whether gcc accepts -g... yes
checking for c++... CC
checking whether the C++ compiler (CC ) works... no
configure: error: installation or configuration problem: C++ compiler cannot create executables.
in config.log I see :
configure:2162: CC -o conftest conftest.C 1>&5
*./configure: CC: not found*
configure: failed program was:
#line 2157 "configure"
#include "confdefs.h"
int main(){return(0);}
I've read that if I try: export CC=gcc before ./configure it should work.. Well it didn't ! I've tried symlinking /usr/ucb/cc to /opt/csw/gcc4/bin/gcc , same difference :-/
All necessary packages are there: gcc* from blastwave (CSWgcc4*), binutils, etc. Using SunFreeware is not an option for me.
Now, I'd give up, but I'm hardheaded.. So two options remain :
- Fooling around $PATH and find the right combination : I've tried many, many permutations of the directories in $PATH, no result.
- Managing to make SUNWspro co-exist with GCC. I remember having issues in the past with this, can't recall exactly what, and since I'm in Hell right now with GCC, I don't want to swap a gcc-Hell for a SunStudio-Hell, you see ? :) Anyone has any experience making both coexist peacefully (no $PATH clash, etc) ?
Thanks, people, you've been of great help in the past, hope it'll continue :)

So simple.. I forgot to mention I had the export CC=gcc line, but not the export CXX one ...
Thanks, it worked !
