How to load a plugin from another plugin?

Hi,

I'm trying to load a plugin, which is not located in the plugin-paths of After Effects from another plugin. It seems to load the aex(dll) and execute the main function fine, but afterwards it crashes immediately and I have no idea why.

This is how my pluginLoader-PlugIn looks like:

1. I created a commandHook to be able to trigger the pluginLoad from the Edit Menu

2. for the actual load of the dll I use the following commands:

          AEGP_SuiteHandler    suites(basic_suite);        std::string dllName = "C:/PATH/TO/plugin.aex";        // defining type and order of the arguments of the entry function        typedef A_Err (*args_type)(SPBasicSuite *pica_basicP, A_long major_versionL, A_long minor_versionL, A_long aegp_plugin_id, AEGP_GlobalRefcon *global_refconP);        args_type pluginEntryMethod = NULL;        // loading the dll(aex) and the entry function        # ifdef _WIN32        HMODULE hDLL = LoadLibrary(dllName.c_str());        if (hDLL != NULL)        {            pluginEntryMethod = (args_type) GetProcAddress(hDLL, "EntryPointFunc");        }        else        {            return err;        }        # else        void *pLib = ::dlopen(szMyLib, RTLD_LAZY);        if (pLib != NULL) {            pluginEntryMethod = (args_type)::dlsym(pLib, "EntryPointFunc");        }        else        {            return err;        }        # endif        if (pluginEntryMethod != NULL)        {            // hardcoding the plugin version            A_long mavL = 0L;            A_long mivL = 1L;                       AEGP_PluginID plId;            // to get a valid plugin-id I use this command            suites.UtilitySuite3()->AEGP_RegisterWithAEGP(*globalRefcon, "nameOfPlugin", &plId);            // I create copy of the refcon and the suite            AEGP_GlobalRefcon newRefcon(*globalRefcon);            SPBasicSuite newSuite(*basic_suite);            pluginEntryMethod(&newSuite, mavL, mivL, plId, &newRefcon);        }               # ifdef _WIN32            FreeLibrary(hDLL);        # else            dlclose(pLib);        # endif       

If I run After Effects with the debugger, the EntryFunction of the new plugin runs through without errors. But Then it crashes and stops at random positions: sometimes in the IdleHook of the newly loaded Plugin, sometimes in the MenuHook.

Does anyone have an idea, what I am doing wrong?

btw: when I copy the second plugin in the default Afx-Plugin-Folder it loads fine and seems to work correct.

Thanks for your help!
