[PD-dev] integrating pdlua into Pd-extended

Mon Mar 28 04:07:12 CEST 2011

I think the key is to generate the liblua51.dll.a file using the  
instructions that were just posted, and stick that into the pdlua  
folder, set -L., then -llua51 should just work.  The .dll.a file seems  
to expose the DLL symbols in a way that ld understands.  If that  
works, I'll include it in the build machine.
