Chuck,
There's a bug in LT_PATH_LD (AC_PROG_LD) when called prior to LT_INIT
(AC_PROG_LIBTOOL):
checking for ld used by gcc...
/usr/lib/gcc/i686-pc-cygwin/4.3.2/../../../../i686-pc-cygwin/bin/ld: no
input files
./configure: line 3955: : command not found
Yet this does not occur when the same macro is run by LT_INIT.
Here's the offending hunk:
# Canonicalize the pathname of ld
ac_prog=`$ECHO "$ac_prog"| $SED 's%\\\\%/%g'`
while $ECHO "$ac_prog" | $GREP "$re_direlt" > /dev/null 2>&1; do
ac_prog=`$ECHO $ac_prog| $SED "s%$re_direlt%/%"`
done
The problem is that $ECHO hasn't been defined yet. This is done by
_LT_PROG_ECHO_BACKSLASH, which is called at the beginning of LT_INIT,
but isn't an explicit requirement of LT_PATH_LD, which may be called on
its own. (AFAICS, all other macros which use $ECHO are libtool-internal
and would only be called after LT_INIT.)
Patch attached.
Yaakov

* libltdl/m4/libtool.m4 (LT_PATH_LD): Require _LT_PROG_ECHO_BACKSLASH
to define $ECHO in case it is called before LT_INIT.
