Re: [PATCH] libtool patch for direct-linking-to-dll

[Oops. I replied to Ralf's message without changing the To: address. And since Ralf's message was originally sent to cygwin-apps (where it didn't belong: bad Ralf); my reply went there too: bad Chuck. No cookie.)

Okay, I've actually looked at the patch now. Apparently I misunderstood.

I thought this was a patch to enable using libtool to link against an outside shared library in which the implib was actually a symlink to a DLL -- which I didn't think would require much if any hacking with libtool, so I was curious to see what you did

I didn't realize it was a patch to rip out all of the import-lib building stuff, and replace it with the new link-to-dll support.

I don't think that's a good idea just yet; I hate to be a wet blanket, but I think this should stay out of the main tree for a while. [Basically, I'm nervous about such a radical change in libtool's fundamental behavior this close to its release date].

Now that the appropriate support is in the released binutils, let it simmer for a while -- a long while. If you want to use this in your build of qt/kde, fine by me -- that'd be a good test bed. (I'm sure we can work out something about the 'official packages must only use other official packages to build' so that your qt stuff can be added to the distro. -- see below). If there are no problems after a few months, then we'll look at getting it into libtool 1.5.1 or 1.5.2 or whatever. But not 1.5 -- it's just too big a change. :-(


(*) For instance, libtoolize/autoconf/whatever with the 'stock cygwin version' -- and then supply a *qt* patch that inserts your nifty changes into the qt-3.0.3/ during the qt build process. Or heck, just ship qt patched with your local version of libtool; the autotools are not supposed to be necessary for the "ordinary" user who just wants to compile the package. And hardly anyone will recompile qt on their own, anyway -- they just want to link TO it. So long as it's *possible* (even if difficult; hello cgf-packaging-system <g>) to rebuild your qt on a stock cygwin system, then you're okay IMO.
