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..
