Works fine as long as you don't want or didn't need Run-Time Shared Object support. From my observation, it's Apache's assumptions about FreeBSD's loader (in Configure) that are broken. > This may be of use to anybody using a current ELF system.

Here's what I get on volta.physics.purdue.edu, just CVSup'd and running BETA from 2-3 days ago: --------------------------------------------------------------------------- ===> Registering installation for apache-1.3.2 # volta root /usr/ports/www/apache13 # /usr/local/sbin/httpd Syntax error on line 28 of /usr/local/etc/apache/httpd.conf: Cannot load /usr/local/libexec/apache/mod_info.so into server: /usr/local/libexec/apache/mod_info.so: Undefined symbol "ap_user_id" --------------------------------------------------------------------------- This is the elf loader (ld.so) complaining that it cant resolve symbolic names. Based on the symbol names, I assume that ap_user_id is defined in the httpd binary, and mod_info.so wants to reference it. If I remember from my Linux days, there is some trickery needed to export the names. Another gotcha I found (I don't have this fixed yet) is that FreeBSD aout apparently wants symbolic names in .so files to begin with underscore, which FreeBSD elf apprently doesn't want/require. Apache groks this entirely wrong. For now patches should do, but eventually Apache's Configure should take care of this, IMNSHO. - Steve -- C.
