8:45 p.m.
I'm building Xemacs on a SUN, I ran "config" as follows:
./configure --site-prefixes=/packages/xemacs_21.4.17/xlib
--prefix=/packages/xemacs_21.4.17 --with-gtk --with-jpeg --with-png --with-xpm
--x-libraries=/packages/X11R6.4/lib --x-includes=/packages/X11R6.4/include
I downloaded all of the packages I am configuring with from the web page, and as
you can see I'm trying to compile 21.4.17. There were a few files and links in
the wrong spots, which I fixed (X11 link, libjpg.a, etc). The error that I hit
that I couldn't get around was:
