Actually, for some of us they *are* scary. I thought I was making
some progress (persuaded autoreconf to complete without errors using
the attached -A.patch), but then configure went into an infinite
loop spewing out '=no' lines. That's around the check to see if we
only want udev. But after the test for whether to build static
libraries my configure script has the following :
4 blank lines, 'fi' which vim is highlighting as unmatched,
ac_ext=c
ac_cpp='$CPP $CPPFLAGS'
ac_compile='$CC -c $CFLAGS $CPPFLAGS conftest.$ac_ext >&5'
ac_link='$CC -o conftest$ac_exeext $CFLAGS $CPPFLAGS $LDFLAGS
conftest.$ac_ext $LIBS >&5'
ac_compiler_gnu=$ac_cv_c_compiler_gnu
CC="$lt_save_CC"
[about 15 blank lines here]
ac_config_commands="$ac_config_commands libtool"
[ 4 blank lines ]
# Only expand once:
[ 3 blank lines ]
and then the test for --enable-udev-only, i.e.
# figure out early if we only want udev
# Check whether --enable-udev-only was given.
if test "${enable_udev_only+set}" = set; then :
enableval=$enable_udev_only;
else
(etc.)
Again, this is testing on a completed recent desktop, just hoping
to find out what this approach will do.
I'm attaching the -A patch in case it's useful to someone else
trying this (obviously, diff it against Dan's original), but I don't
think I'm cut out for this.
