%configure macro in /usr/lib/rpm/macros

[Alan Eldridge <alane geeksrus net>]

Anybody here know libtool well enough to help with this?

The %configure macro invokes the %libtoolize macro with the options "--copy 
--force". I am guessing that this causes a replacement of whatever version of 
libtool is already in the source package with the local copy (based on the 
--help output, it seems that way).

Whenever I use %configure on a  KDE package, the KDE configure ends up 
bombing out because libtool eventually gets given the option "--tag=CXX", 
which it knows nothing about, and so it croaks.

The libtool that comes with a KDE package, of course, does know about this.

I've ended up just doing "%define __libtoolize true" to nullify the command, 
but can anybody explain what's really going on?  

There's no mention of libtoolize on the KDE FAQs that I could find, and 
autoconf, automake, and libtool seem to be in the same category as sendmail 
configuration ... nobody knows how it works, and just don't touch it, 'cause 
even if it's broken, you'll probably break it worse.
