AW: PerlSwitches -M and @INC
Hi, after i recompiled the newest versions of perl, apache and mod_perl on my home computer with the appropriate debug switches, i cannot reproduce the Segmentation Faults any more, too. At my machine at work i found out that the problem had to do with the DBI module, which i additionally loaded. After installing the newest version of DBI and/or not loading this module, no Segmentation faults happened any more. Concerning the PerlOptions: From the results below i conclude: +Parent means everything is new in the virtual host. You have to add the libs and paths you need all there. +Clone means everything is cloned from the main configuration. To add a private lib path you have to call a second startup script with the lib path you need included. The PerlSwitches -Mlib=.. in the virtual host section are ignored. +inherit makes no difference at all (probably i did/do not understand that option) So after everything is clear now (i have to sleep one night over it) i will continue moving from 1.3 to 2.0. Thanks for your help Helmut 1) httpd.conf: PerlRequire /tmp/install/apache2/conf/startup.pl PerlSwitches -Mlib=/test1 NameVirtualHost 127.0.0.1:8080 VirtualHost 127.0.0.1:8080 ..
