Subject AW: MP1 -> MP2 migration Problems.
Date Thu, 14 Feb 2008 13:38:50 GMT
Hello again,

i did a new setup of our Apache and mod_perl2 with your hint´s.. Configured again some startup.pl
stuff. but no luck 8-)

Error is still the same in error.log from apache.

[Thu Feb 14 14:33:58 2008] [error] [Thu Feb 14 14:33:58 2008] -e: Can't locate object method
"request" via package "Apache" at /usr/lib/cgi-bin/test1.pl line 4.\n

Code looks like this for test1.pl
#!/usr/bin/perl
my $r = Apache->request;
$r->send_http_header('text/plain');
$r->print("mod_perl rules!\n");

Hmm. Is someone able to use this code under apache2 with compat enabled. Perhaps it is broken
in some ways ?

bye
Roman

Of course, what I forgot to mention below - and sorry if you know that 
already - is that whichever perl modules you pre-load in your main 
Apache server config via the startup.pl script, you do not need to "use" 
anymore in all your perl scripts or Apache/mod_perl handlers.
(At the cost of having them (insibly) duplicated in all the children 
processes).
But it may simplify your migration problems, and you can always tune 
this later.
