Well since I've reinstalled Linux on my main machine, I've been playing with AC3D a bit and it seems to work better than under windows... Except I can't get most of Hippie's plugins to work. I recompiled them succesfully, but at startup I get a message like this:

Here is a crude Makefile to build the plugins under Linux, you need ac_plugin.h in the directory and a symbolic link "ofiles" which points to the ac3d object files directory
(ln -s /path/to/ac3d/ofiles ofiles).
Some of the plugins have DOS style paths in them where they call tcl routines, the backslashes need to be changed for forward slashes.

CC=gcc
