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(*modul e_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. Regards Alex To
