Since that blog post, Don Heyse the author of ldglite emailed me about the ldglite bug I ran into. A bit more detail and a testcase later, and Don had a fix for ldglite 1.2.4 in CVS. Thank you, Don -- you are awesome.
LPub4 is a program by Kevin Clague for creating high-quality instructions for Lego models. It runs on OS/X and Windows. And now with a few patches, it runs on Linux (tested on Fedora 11) as well.
There still seem to be some issues with rendering. There are two rendering options: LDView and ldglite. LDView 4.0.1 segfaults under Linux and the latest from CVS does not build under Linux; I have not dug deeply into the issues there. ldglite requires a wrapper script to scale some of the values LPub passes it to get the model to render. Just configure LPub to call the wrapper script instead of ldglite directly.
Checkout LPub from CVS
cvs -d :pserver:firstname.lastname@example.org:/cvsroot/lpub4 co LPub4 LPub4
Then apply these patches:
Then build the lpub binary.
