Sorry, I figured it out by myself. It was because my code file is mod_mymodule.cpp. I changed it to mod_mymodule.c and the module loaded file. So I take it as FS accepts only C library but not C++ ?

Subject: Visual Studio 2008 Pro SP1: switch_loadable_module.c:871 Error Loading module .... **dll sym error [127l]

Hi, excuse me if this is already asked where else but I did browse through the mailing list and I couldn’t find anything related. I tried to create a new end point module by copying the mod_skel to mod/endpoints/my_module folder.

I modified “skel” to my module name and basically I leave no codes in the load function, just a few lines to test if the new module is working. These few lines are:

*module_interface = switch_loadable_module_create_module_interface(pool, modname);

      modem_endpoint_interface = (switch_endpoint_interface_t*)switch_loadable_module_create_interface(*module_interface, SWITCH_ENDPOINT_INTERFACE);

      modem_endpoint_interface->interface_name = "modem";

      switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_NOTICE, "Hello World!\n");

//

//do_config(SWITCH_FALSE);

//

      SWITCH_ADD_API(api_interface, "modem", "Modem API", modem_function, "syntax");

/* indicate that the module should continue to be loaded */

return SWITCH_STATUS_SUCCESS;

It compiles but the module can’t load properly. I received the following error:

2009-11-01 19:18:10.551180 [CRIT] switch_loadable_module.c:871 Error Loading module D:\Projects\freeswitch\Debug\mod\mod_mymodule.dll

**dll sym error [127l]

**

I tried to load module normally at the FS console but “load mod_skel” and “load mod_mymodule” gives the same error.

Would someone tell me what do I miss here.

Btw, I looked at mod_sofia and mod_iax, this line of code could compile in those 2 modules.

modem_endpoint_interface = switch_loadable_module_create_interface(*module_interface, SWITCH_ENDPOINT_INTERFACE);

The same line of code couldn’t compile in my module coz VS complains: cannot convert from void* to switch_endpoint_interface_t*. I know C++ require more type-safe conversion than C but anyone got the same error?

And how would I search in the mailing list ? Sorry for this dumb question but I can’t seem to find out how to search in the archives. For now, before posting anything, I need to try to browse through all the postings first, which is

quite tedious to do.
