Hi,
Can some one help me locate the C++ compiler in AIX machine.The version of the AIX is 5 and the release number is 3. I am looking at the native compiler and not the gnu compiler.
Is xlC the C++ compiler as mentioned above. I find that all the commands cc, xlc, xlC all point to the same link in the AIX machine. So confused whether this is a C compiler or a C++ compiler.

Also I have a code base, already compiled using the gnu compiler and need to compile it now using the aix native compiler. I would like to get some pointers in that direction too.
In the overview of “XL C Enterprise Edition for AIX”, a link in the IBM site, there is a bulleted point as “Also includes facilities to help you port application code from GNU C”.

It would be great, if I could some help in resolving my above mentioned issues.

Thanks in advance

/usr/vac/bin/xlc ANSI C compiler, using UNIX header files.
/usr/vac/bin/c89 ANSI C compiler, using ANSI C header files." [1]

I imagine that the binary/executable that each of the above link to examines the command used to invoke the compiler to determine which version of the compiler should be used.

You might want to start out by looking at the AIX IBM Compiler Information Center here
http://publib.boulder.ibm.com/infocenter/pseries/v5r3/index.jsp?topic=/com.ibm.compilers.doc/welcome.htm

There's also a Redbook on 'Developing and Porting C and C++ Applications on AIX' that might be of some use here:
http://www.redbooks.ibm.com/abstracts/SG245674.html

Also, this Redbook, 'AIX 5L Porting Guide', might also be of some help in porting:
