Howdy all,
I got PD-extended to build a 64bit deb for Ubuntu 8.10 Intrepid following the guide on puredata.org:
http://puredata.info/docs/developer/64BitLinux I added a few notes to the guide and I will see what happens when I setup my full environment.
For pdp:
I had to add a 3rd argument to the open function on line 141 in /externals/pdp/modules/generic/pdp_rawout.c,
apparently creating new files now requires a permission for said file. I used 0666.
