Here's an update. I forgot that  are quotes in autoconf, so you
usually end up using test instead. I still didn't test it works all
the way, but I think configure should run.
Allow me to get on my soapbox here for a minute.
Nearly all the energy in LFS is used on building packages and all the
associated issues with bootstrapping systems. Ask yourself, what
percentage of the packages you're building use the autotools? 50%?
75%? 90%? The percentage is high regardless. IMO, if what you're
interested in is building packages, then learning the process the
build is created would be a great investment. I see so much time spent
here trying to work around build issues and basically guessing at how
the build works. I almost never see someone actually diagnose the
issue at the root when the autotools are involved.
The autotools are unusual, but they really aren't that complex. One of
my real "oh" moments when I was still building LFS was when I saw an
analysis Greg did of a configure bug and realized that it really
wasn't that complex at all. At Xorg a guy showed up and wanted to help
on build issues but had never seen the autotools before. Within a few
months he was squashing bugs all over the place and now he's basically
the expert there. It's a really handy skill set because of the
ubiquity of the autotools.
The documentation is very good:
Old, but will teach you the basics:
I will now return to lurking.
