The use of libtool with autotools causes problems on the Mac: the
libtool script eats for unknown reason the "-framework foo" arguments
given to the compiler (this argument is a combination of -I and -l: it
allows to use a given framework for cpp and linking). This breaks
compilation with some versions of Qt (depending how the pkg-config file
has been coded, AFAICS).
The problem does not exist in trunk where André got rid of libtool.
Since doing that on branch is a bit dangerous, I propose the following
patch that I found on a kde/mac-related website
http://ranger.befunk.com/patches/libtool-framework.patch
Reading the patch shows that the code only touches darwin-related code
paths, and only the -framework option. I am reasonably confident that it
does not break something else, but who knows...
Juergen, I'd like to apply this patch to branch, with the understanding
that we'll revert it on any problem. The alternative would be to ask
people to try it, but I feel nobody will do that until it is in branch.
What I do know is that I managed to comple with it on Leopard and that
my linux builds still work as they should.
