Asterisk crash @ start: Already have an application 'Pickup'

Asterisk Asterisk Support

Ubuntu Hardy, Asterisk 1.4.24.1 (but earlier versions did the same!)
When I do:
asterisk -vvvvvvvvgc
I get this (only the last page copied here):

What causes this? I have searched the config files for asterisk in /etc, but cannot find a reference to “Pickup”.

How do I fix this?

The list of applications to register comes from the code. That may mean that you have a mixture of two incompatible versions in your modules directory.

3

So if I delete by complete installation and redo it all, including /etc/asterisk/ I should not have this problem any more?

(I did have previous versions of the system, although it was never working…)

I have removed all asterisk folders and config files by finding all directories and files referring to asterisk (as listed below), and then I recompiled asterisk, zaptel and asterisk add-ons, but I still get the same error.

whereis asterisk

asterisk: /usr/src/freepbx-2.5.1/asterisk.conf /usr/src/freepbx/asterisk.conf /usr/sbin/asterisk /etc/asterisk /usr/lib/asterisk /usr/include/asterisk.h /usr/include/asterisk /usr/share/man/man8/asterisk.8

I deleted all the above, except for all those in /usr/src.

Strangely enough though, if I start asterisk with the -cvvvvv option, it starts fine, but as soon as I use “/etc/init.d/asterisk start” or the FreePBX control script “start_asterisk start”, I get the error as mentioned.
