Compiling code that use __gnu_cxx function, with Sun Studio compiler

[Carfield Yim]

HI, I work with some code that using __gnu_cxx::hash_map, and it was
compile using g++, now we get a new M5000 server and we would like to
recompile our code using Sun Studio compiler to get better
performance.

Can we include something and make our old code work? or we need to
change our source code to use the standard library ? Which should be /
opt/SUNstdxpr/prod/include/CC/stlport4/hash_map , right? BTW, any
code sample for that?

The sun studio forums are the place to ask this.

I wasn't aware that Sun has a decent C++ compiler, but maybe they
have caught up.

No, but if you can be sure you can both are in reality the good old
SGI STL container, you should probably just wrap it in a tiny header
and a my_hashmap namespace. (Hm, didn't Boost already to that?)

They caught up years ago. While their early compiler and it's half-
assed
roguewave library was pretty bad, the 6v2 and later versions were
pretty
nicely standard compliant and efficient. More than I could say for G+
+
on that platform.
