howdy,
usually can't locate loadable object means it's looking for some kind of
shared library (i.e. a .DLL or .so file) and either can't find it, or
can't open it (permissions issues.) for DBI it may be looking for a
shared library to access the specific database type you're using (such as
libmysql.so or something similar- i would include a real filename but
i'm at home and my dev boxes are at work behind the firewall.)
i would start by reading /usr/.../DBI.pm (where the error message is
happening), look at line 243, and see if you can figure out what library
it's trying to load. then figure out why it can't load, whether it's a
permissions issue or a missing symlink or something.
also remember that the built-in @INC for mod_perl may not the same as the
built-in @INC for your command-line perl interpreter. the list above is
the built-in @INC for the mod_perl you're running, and running perl -V
will show you the built-in @INC for your command-line perl.
if you've upgraded perl, DBI, or DBD::mysql since you compiled mod_perl,
it may be looking for old library files that don't exist anymore.
you may also want to try running your httpd with the -X parameter,
inside of a program like strace or ltrace, and read the output file to
see what library it's trying to load. it can generate a LOT of output,
but it will show you exactly what filename it's trying to open and what
the error code was (i.e. ENOENT=file not found, EPERM=permissions, etc.)
try something like this:
ltrace -S -o trace.out /usr/sbin/httpd -X
you won't see anything extra on the screen while it's running, and it will
run much more slowly than normal (you don't want to leave it running like
this all the time.)
try hitting your script from a browser. after it doesn't work, go back to
the console where this command is running and hit control-c to shut down
httpd. read through the trace.out file and see if you can find the
open() or dlopen() call that's failing. you may be able to use the time
stamp from your error_log to find the right place in the trace output
file.
some other things to try...
you may want to run ldconfig to rebuild your shared library cache and
see if that helps (it doesn't hurt anything to run it whenever you feel
like it.) start/restart your httpd after it finishes, and then try your
script again.
if it's a permissions issue (and even if it's not) i have a script that i
call pfix, which fixes permissions on the perl library directories.
some CPAN modules, when you install them as root, install the files with
root-only permissions. i run this script as a cron job every day, along
with every time i install anything from CPAN. the script looks like this:
#!/bin/sh
chmod -R go=u-w /usr/lib/perl* /usr/local/lib/perl* /www/perl
sorry i can't be more help than this, i haven't switched to perl 5.8,
apache 2, or mod_perl2 yet, which means i can't do a live test myself.
