How can you find out the version of xlC installed on AIX box

Question

So this should be quite simple but just want to see if I got it right.

I am trying to find out what version of xlC compiler is installed on AIX box.

I tried xlC -v/xlc --version which is not supported by the compiler.

I tried lslpp -L | grep xlC

I get following output but it confuses me (i am releatively new to UNIX world)

  xlC.adt.include            8.0.0.0    C     F    C Set ++ Application
  xlC.aix50.rte              8.0.0.0    C     F    C Set ++ Runtime for AIX 5.0
  xlC.cpp                    6.0.0.0    C     F    C for AIX Preprocessor
  xlC.msg.en_US.cpp          6.0.0.0    C     F    C for AIX Preprocessor
  xlC.msg.en_US.rte          8.0.0.0    C     F    C Set ++ Runtime
  xlC.rte                    8.0.0.0    C     F    C Set ++ Runtime

This is list on installed packages on box but whats the significance of listing .cpp file.

And which version is on my box?

6.0 or 8.0

Thanks

Answer 1

Try xlC -qversion

Answer 2

Try lslpp -l | grep -i vacpp and check for lines about the C/C++ Compiler:

vacpp.cmp.core            9.0.0.11  APPLIED    IBM XL C/C++ Compiler
vacpp.cmp.core             9.0.0.0  COMMITTED  IBM XL C/C++ Compiler

This means I have 9.0 installed with a subsequent PTF added. My corresponding xlc version information looks like this:

% xlc -qversion=verbose
IBM XL C/C++ Enterprise Edition for AIX, V9.0
Version: 09.00.0000.0011
Driver Version: 09.00(C/C++) Level: 090810
C Front End Version: 09.00(C/C++) Level: 090730
C++ Front End Version: 09.00(C/C++) Level: 090730
High-Level Optimizer Version: 09.00(C/C++) and 11.01(Fortran) Level: 090812
Low-Level Optimizer Version: 09.00(C/C++) and 11.01(Fortran) Level: 090902

Also the xlc/rte entries you found are for the C/C++ Runtime, which will depend on the OS version and are not as closely linked to the compiler version. This source of confusion is also mentioned in the link below.
