Gnudl should run nicely on any platform where guile compiles. I do development on linux, IRIX 5.3 and SunOS 4.1.4.
You can obtain gnudl from the anonymous ftp site nis-ftp.lanl.gov:pub/users/rosalia
But you must first install guile, available from
ftp.cygnus.com:pub/lord
Gnudl version proto2.4 compiles with the guile-iii snapshot, but you should take a look at Mark Galassi's notes on learning libguile since it describes how to solve some problems that come up when installing guile-iii.
Users in the NIS division computers in Los Alamos can make a directory for gnudl with a link to Mark Galassi's gnudl directory:
ln -s ~rosalia/gnudl/proto2/RCS ./RCS
then you also have to copy over the directory marklib:
cp -r ~rosalia/gnudl/proto2/marklib ./marklib
and then just type gmake and GNU make will automatically check
out the files and compile them. At that point ./gnudl will
execute the program. Make sure your X Window environment is properly
set up.
