Compiler Notes - xlC

The makeC++SharedLib utility must be in your PATH to build shared libraries. From IBM's C and C++ Application Development on AIX Redbook:

" The second step is to use the makeC++SharedLib command to create the shared object. The command has many optional arguments, but in its simplest form, can be used as follows: "
```
/usr/vacpp/bin/makeC++SharedLib -o shr1.o cplussource1.o
```
" The full path name to the command is not required; however, to avoid this, you will have to add the directory in which it is located to your PATH environment variable. The command is located in the /usr/vacpp/bin directory with the VisualAge C++ Professional for AIX, Version 5 compiler. The command is installed in /usr/ibmcxx/bin with the CSet++ 3.6 compiler and in /usr/lpp/xlC/bin with the CSet++ 3.1 compiler. "

VisualAge C++ for AIX, Version 6.0

No known problems up to now

VisualAge C++ for AIX, Version 5.0

Qt builds smoothly with VisualAge C++ for AIX provided you install the upgrades to at least version 5.0.2.0.

VisualAge C++ for AIX, Version 5.0, 64-bit

Please apply fix 4Q2001 and APAR IY23677.

IBM C and C++ compilers for AIX, Version 3.6

We do not get much feedback about this compiler anymore. We suggest you upgrade to at least VisualAge C++ for AIX, Version 5.0. For the record, users had reported success building Qt with version 3.6.6.

C Set++ for AIX, Version 3

We do not get much feedback about this compiler anymore. We suggest you upgrade to at least VisualAge C++ for AIX, Version 5.0. For the record, one or more versions of xlC (including version 3.1.3.0) include faulty system header files. Typically you get an error message about several libc functions with C linkage, e.g. like this:

xlC -c -+ -O3 -qstrict -D_BSD -I/temp/rzis/tmp/qt/include/tools/qbuffer.cpp -o qbuffer.o
"/usr/lpp/xlC/include/sys/time.h", line 13.5: 1540-089: (S) More than one function "setitimer" has non-C++ linkage.
