AIX默认是不带编译器的,所以如果要自己编译Perl,需要先安装编译器。开源的gcc自然可以算是最佳选择。
在64位平台的AIX中,如果选择使用gcc来编译perl源代码,默认情况下是编译成32位的版本。这样在编译DBD::Oracle的时候也需要选择正确的32位库,否则无法编译成功。也可以选择将Perl编译成64位的,这样在64位平台上应该更方便些,很多依赖库的路径使用默认即可。
编译成32位Perl
$./Configure -des -Dprefix=/opt/perl -Dcc=gcc $make && make install
编译成64位Perl
$./Configure -des -Dprefix=/opt/perl -Dcc='gcc -maix64' $make && make install
注:gcc在linux下64位编译选项为-m64,在HP-UX下64位编译选项为-mlp64。不同平台下需要编译64位程序,选用不同的选项即可。为了确认编译后的版本,可以使用-V选项运行perl:
$./perl -V
