3:25 a.m.
Greetings!
I returned from a week away from my principal development machine to
find that the new autoconf 2.59 support had been checked in. Good
show, Malcolm!
I've noticed a snag though: libpng detection doesn't work, at least on
my system. I believe this is because -lz appears before -lpng in the
link line. Here's what's happening:
CC=gcc ../../src/xemacs-21.5-2005-03-12/configure
'--prefix=/usr/local/xemacs-21.5-2005-03-12'

'--disable-mule' '--disable-dialogs' '--disable-widgets'
'--with-package-path=/usr/local/site-packages::/usr/local/xemacs-packages'
checking for png.h... yes
checking for png_read_image in -lpng... no
If I look at config.log, here's what I'm seeing:

When I configure --with-libs=-lz, png is found appropriately.
Thanks in advance,
