no, you must end up with a .dll file.
you can use the makefile in pd\doc\6.externs
you just have to modify
line 8 with the actual external name
line 13 for your VC path
line 15: edit PDNTINCLUDE putting your pd path
line 21: put the correct path to pd.lib

when you have that dll you will have a puredata object, put it into the 
extra folder (or keep it in your working directory) and you'll be able to 
use it.

ciao,
