RE: Can't locate object method "new" via package "Apache::Request" (via Mason)...SOLVED
It's hard to generalize because in some cases the shared object file may actually not be installed. However, there should probably be something in the documentation that tells the user to make sure that the LD_LIBRARY_PATH variable and/or the /etc/ld.so.conf file include the usual default installation paths for required packages. -DeAngelo -Original Message- From: Perrin Harkins [mailto:perrin@;elem.com] Sent: Friday, November 08, 2002 1:10 PM To: DeAngelo Lampkin Cc: mod_perl Mailing List Subject: Re: Can't locate object method "new" via package "Apache::Request" (via Mason)...SOLVED DeAngelo Lampkin wrote: > And of course the other reason is that if the solution to the problem > was so obvious from the error message, somebody would have posted a > solution before I figured it out (with help from you guys).

>Huh? >It tells you EXACTLY what is wrong. No, not really. One reason is that it's not immediately clear (to me) which file can't be loaded. Is it Request.so or libapreq.so.1 that can't be loaded? This ambiguity is further blurred when you know both files are installed. And of course the other reason is that if the solution to the problem was so obvious from the error message, somebody would have posted a solution before I figured it out (with help from you guys). Searching the mailing list archives indicates that method name resolution is not exacly a new problem with mod_perl. Just ask this guy => http://lists.fsck.com/pipermail/rt-users/2002-September.txt. It's the exact same problem with the exact same error message, only in different clothing (he's having trouble with the Apache::Cookie object rather than the Apache::Request object). In the interest of full disclosure, other possible solutions include resetting /etc/ld.so.conf or the LD_LIBRARY_PATH variable to include more places to look for shared object files (only recently figured this out). But again, unless you're somewhat experienced or have encountered this class of bug before, this won't necessarily be the obvious place to look at first. Anyway enough of my babbling. Now that the answer is out there, hopefully it'll help out the poor souls who run into this issue in the future.

As a quick follow-up, the "PerlModule Apache::Request" line is NOT needed in the httpd.conf file for Mason to work.
