gcc 3.1.1 and Sun Forte 6.2 libs

[Mark Crosland]

Hello,

Is it safe and sane to compile/link an application with gcc 3.1.1 that
also links in libraries built with Sun Forte 6.2 ?

Solaris 2.8, sparc.

Thanks,
Mark

No, it is not.

GCC 3+ and ABI

[Tom Browder]

I'm not sure about the impact of the various flavors of ABI from gcc 3.0
onwards.  Statements are made that code compiled with g++X is not
compatible with g++Y, but I seem to be able to link and run successfully
with g++-3.1.1 code linked with g++2.95.1 library code (all on i386
hosts, various RedHat distributions from 7.0 through 7.3.

Am I just lucky and awaiting a big surprise?

Thanks.

Hi Tom,

Are you linking C++, or C code?

The C ABI is, I've heard, the same.

The C++ ABI has undergone a significant overhaul.  I think along the lines 
of exception handling infrastructure, name mangling, register usage 
protocols (on select platforms), C++ streams and other I/O, RTTI support 
and infrastructure, exceptions thrown out of a shared library (.so, .dll) 
which not supported in 2.95.

Those are just some of the big ones.  I'm sure that the website has more 
intimate (and correct!) details, as well as some of the GCC gurus on this 
forum.  But that should be good enough for a heads up.

Sincerely,
