[asterisk-dev] Manual loading of modules with AST_MODFLAG_GLOBAL_SYMBOLS broken

[Daniel Ferrer]

I reported this some time ago to the list (I get no response from 
anybody by the way :) ).
Module loading is broken when trying to load manually a module that 
exports symbols (typically res_* modules).

Now I've found it, and attached a patch:
https://issues.asterisk.org/jira/browse/ASTERISK-18227

Hi, I've problems with module dependency, or there is something that I
don't understand properly.
For example, app_queue.so depends on res_monitor.so being loaded, and I
did the following test:

- I put in the sample modules.conf: noload =>  res_monitor.so
- I start asterisk, and try to load  manually, first res_monitor and
then app_queue
- Module loading fails for app_queue:

*CLI>  module load res_monitor.so
   Loaded res_monitor.so =>  (Call Monitoring Resource)
*CLI>  module load app_queue.so
[2010-10-14 13:09:20] WARNING[18751]: loader.c:434 load_dynamic_module:
Error loading module 'app_queue.so':
/usr/lib64/asterisk/modules/app_queue.so: undefined symbol:
ast_monitor_start
[2010-10-14 13:09:20] WARNING[18751]: loader.c:777 load_resource: Module
'app_queue.so' could not be loaded.

If I coment the "noload =>  app_queue" all is obviously ok.

I have the same problem in a custom module app_* developed by us, that
depends on a resource that must be loaded before: it is only loaded
correctly at asterisk startup, but I cannot load it manually.

This is normal? It's an asterisk 1.4 issue?

Thanks for your comments
regards,
