AIX does not ship -an ANSI compliant C compiler with AIX by default, but binary builds of -gcc for AIX are widely available. A version of gcc is also included in -the AIX Toolbox which is shipped with AIX. - -=head2 Supported Compilers - -Currently all versions of IBM's "xlc", "xlc_r", "cc", "cc_r" or -"vac" ANSI/C compiler will work for building Perl if that compiler -works on your system. - -If you plan to link Perl to any module that requires thread-support, -like DBD::Oracle, it is better to use the _r version of the compiler. -This will not build a threaded Perl, but a thread-enabled Perl. See -also L<Threaded Perl> later on. - -As of writing (2010-09) only the I<IBM XL C for AIX> or I<IBM XL C/C++ -for AIX> compiler is supported by IBM on AIX 5L/6.1/7.1. - -The following compiler versions are currently supported by IBM: - - IBM XL C and IBM XL C/C++ V8, V9, V10, V11 - -The XL C for AIX is integrated in the XL C/C++ for AIX compiler and -therefore also supported. - -If you choose XL C/C++ V9 you need APAR IZ35785 installed -otherwise the integrated SDBM_File do not compile correctly due -to an optimization bug. You can circumvent this problem by -adding -qipa to the optimization flags (-Doptimize='-O -qipa'). -The PTF for APAR IZ35785 which solves this problem is available -from IBM (April 2009 PTF for XL C/C++ Enterprise Edition for AIX, V9.0). - -If you choose XL C/C++ V11 you need the April 2010 PTF (or newer) -installed otherwise you will not get a working Perl version. - -Perl can be compiled with either IBM's ANSI C compiler or with gcc. -The former is recommended, as not only it can compile Perl with no -difficulty, but also can take advantage of features listed later -that require the use of IBM compiler-specific command-line flags. - -If you decide to use gcc, make sure your installation is recent and -complete, and be sure to read the Perl INSTALL file for more gcc-specific -details. Please report any hoops you had to jump through to the -development team. - -=head2 Incompatibility with AIX Toolbox lib gdbm - -If the AIX Toolbox version of lib gdbm < 1.8.3-5 is installed on your -system then Perl will not work. This library contains the header files -/opt/freeware/include/gdbm/dbm.h|ndbm.h which conflict with the AIX -system versions.
