Viable compilers for Apache and third-party plug-in modules

There are many viable compilers and compiler levels, which have been tested, that we can use for Apache and third-party plug-in modules.

Apache modules and third-party module testing incorporated the compilers and compiler levels that are included in the following list. Other compilers may work, but testing was limited to the following environments:

• AIX V5.0.2.3: C or VisualAge C++ Professional

• HP_UXaC++ Compiler (A.03.xx)

• The compilers that were tested vary by platform:

  • Linux on Intel: gcc 3.2.2

  • Linux on POWER: gcc 3.2.2

  • Linux on zSeries: gcc 3.2

• SunWorkShop V5.0

• Microsoft Visual C++ 6.0

• z/OS V1R6.0 C/C++

The primary concern with determining if a different compiler can be used is when the third-party module, or libraries it uses, are implemented in C++. Different compiler versions may use different C++ application binary interfaces (ABI), in which case the behavior is undefined.
