Hi all . I want/try/need to buid an external with vc++6 and the dll is created without any error nor warning, but pd's console says :

# tried D:\obj1\Debug\obj1.dll and succeeded # load_object: Symbol "obj1_setup" not found # newpd # ... couldn't create

i'm not a developer but i'm sure it's nothing important can someone help ?

You probably forgot to put this magic incantation in front of the declaration of obj1_setup:

__declspec(dllexport)

This tells vc to export the name. Other compilers seem to do this automatically or with flags like -shared and -export_dynamic.

I imagine that "declaration of obj1_setup:" means , in the obj1.c , where it's writen "void obj1_setup(void)" But where shall i put this magic incantation ? ( and how ;?) I tried here and there , but even if vc do not return errors, i have the same Symbol not found from pd ...

ps : the obj1.c is the one given in the pd/doc/6.externs/obj1.c

Yes it's like: __declspec(dllexport) void obj1_setup(void); for the prototype, and __declspec(dllexport) void obj1_setup(void) for the function.

Magic °) ! Thank you : it works perfectly .

Shall we put this line in the pd/doc/6.externs/obj1.c ?
