[PD] compiling helloworld on winXP

[.: monsular :.]

ok, thanks a lot cdr!

i could now compile the project. but(!)..

the outputted file was a helloworld.dll

i now tried to import the .dll with 
    "pd.ex -lib c:/path/to/external/helloworld" (tried wit and without file extesion .dll)

but, what else .... this error followed in pd:

-: can't load library
load_object: Symbol "helloworld_setup" not found
c:/path/to/external/helloworld: can't load library

and now?

the helloworld setup function is in the sourcefile.
may this cause by a wrong compiled dll?
or did i do something wrong at the importing?


    

top error snipped, but be sure to send -DNT (or -DMSW) to the preprocessor

the linker needs some hints to find libpd, aka pd.dll (or pd.lib with MSVC).  you could rename it libpd.dll, then -lpd would work (with GCC), or simply add the path to pd.dll to the linker arguments (absolute path, or relative if you did  -Lbin/)

dll..

if you are using MSVC you additionally have to -DPD_EXTERNAL and weird tricks with declspec(dllimport) or something, so GCC is definitely simpler from a user standpoint..and if you are using GCC, add -mms-bitfields to the compiler flags so your external wont segfault when running in a MSVC-compiled host..

goodluck, looking forward to yer externals..
