We recommend using the latest DGD in the GitHub repository. You're also going to have to make some code changes.
How to Build
From an appropriate directory, here is how you would clone and build DGD:
git clone git@github.com:dworkin/dgd.gitcd dgd/srcmake DEFINES='-DUINDEX_TYPE="unsigned int" -DUINDEX_MAX=UINT_MAX -DEINDEX_TYPE="unsigned short" -DEINDEX_MAX=USHRT_MAX' -DSSIZET_TYPE="unsigned int" -DSSIZET_MAX=1048576 clean install
This should build an interpreter named "dgd" in dgd/bin/dgd. Go ahead and run it. It should fail with a message about usage, essentially telling you that you have to supply a config filename. Great! You didn't supply the filename, it complained and exited. So it's working.
Random Notes
On a MacOS X host, "long" means an eight-byte type, not a four-byte type. Try to use "int" (four-byte on both Mac and Linux) or "long long" (eight-byte on both) rather than "long", which varies between them.
