To install IBM's "XL C/C++ Enterprise Edition V8.0 for AIX" (5724-M12),

as root on an AIX 5.3 system with the new sunas1's /dfs mounted,



  cd /dfs/software/base/C_C++.v8_For_AIX_5.3

  smitty installp everything



Then if you want the normal links in /usr/bin (what the old

/usr/ibmcxx/bin/replaceCSET did), run the replaceCSET script I wrote

from that directory:

  ./replaceCSET



ln -s -- /usr/vac/bin/xlc /usr/bin/cc

ln -s -- /usr/vac/exe/default_msg/vac.txt /usr/share/man/cat1/cc.1

ln -s -- /usr/vac/bin/xlc /usr/bin/cc_r

ln -s -- /usr/vac/exe/default_msg/vac.txt /usr/share/man/cat1/cc_r.1

ln -s -- /usr/vac/bin/xlc /usr/bin/xlc

ln -s -- /usr/vac/exe/default_msg/vac.txt /usr/share/man/cat1/xlc.1

ln -s -- /usr/vac/bin/xlc /usr/bin/xlc_r

ln -s -- /usr/vac/exe/default_msg/vac.txt /usr/share/man/cat1/xlc_r.1

ln -s -- /usr/vac/bin/xlc /usr/bin/xlC

ln -s -- /usr/vac/exe/default_msg/vac.txt /usr/share/man/cat1/xlC.1

Subroutines in C:



    static = Internal Use Only.  Subroutine name is not exported to other modules.

             Symbol will be " t " in the output of a nm command.



    inline = This code can be "inlined" instead of making a subroutine call if the

             compiler chooses to do so.

             Symbol will not be in the output of a nm command.



    __init = This subroutine is defined elsewhere, e.g.

             void __init page_cache_init(unsigned long mempages) in mm/filemap.c

             Symbol will be "00000000 T" in the output of a nm command.



===================================================================================



Object Modules - .o Files:



Use nm to see symbols from the load map of an object file.



   Common Symbol Codes:  Lowercase = The symbol is local.  Uppercase = global.

         A = The symbol is Absolute and will never change

       b/B = Uninitialized Data Section (known as BSS - I dunno why.)

       d/D = Initialized Data Section

       n/N = Debugging Symbol

       r/R = Read/Only Data Section

       t/T = Text (Code) Section

         U = Symbol is Undefined



FWIW, a Linux kernel System.map has 7706 d symbols,

                                    4571 t symbols,

                                    3370 R symbols,

                                    3128 T symbols,

                                     606 b symbols,

                                     525 D symbols,

                                     310 B symbols,

                                      57 r symbols,

                                and   19 A symbols.
