Subject APR buildconf and libtool
Date Sat, 27 Jan 2001 05:22:17 GMT
APR's buildconf has (Greg Stein wrote this):

	ltfile=`cd $ltpath/../share/aclocal ; pwd`/libtool.m4

This doesn't work for me; I have libtool installed with exec_prefix
different from prefix.

Here is my proposed fix.  It's much grosser in that it parses
human-readable libtoolize output which could easily change form in a
future version of libtool (libtoolize really ought to have a way of
asking for it in machine-readable form), but it's much cleaner in that
it doesn't make assumptions about how libtool was installed.

Incidentally, perhaps buildconf should nuke ltconfig and ltmain.sh
before running libtoolize, to ensure consistency.  (Then again,
buildconf shouldn't have to know the list of files which will be
copied, especially since ltconfig is going away in the next version of
libtool.)
