Hi,

Version 9i Release 2. Pro*C. Version 9.2.0.1.0

I am trying to port a Pro*C program from solaris 2.8 (Sun's C++ compiler) to Linux and Mac OSX using the g++ compiler and am coming up with some interesting link problems.

It seems the c++ compiler on solaris places some symbols in the COMMON section and the c++ on Darwin places the same symbols in the DATA section. I tried the same code on Linux and the same symbols were placed in the BSS section. So then I tried to compile the same c++ code with g++ on solaris and it didn't work. Any ideas?

Darwin: (Doesn't link)
