Yes, but I believe when linking you only specify the main name of the framework. To have it use the debug version you set the DYLD_IMAGE_SUFFIX environment variable to _debug like this: DYLD_IMAGE_SUFFIX=_debug and that causes it to load the debug framework at runtime. It can also be enabled from within XCode.

Ok, so we need to support that on Windows. I.e., if we're linking against
the debug Qt build, we generate debugging ('d') libraries.
On MacOS X, from what I hear, the frameworks have both libraries -- i.e.,
nothing + "_debug". So it looks like we should support the same.
On all the other Unix, I'd rather we didn't introduce anything right now.
Switching libraries is very useful and I'd rather not have to rebuild my
whole KDE just because I want to debug something in kdecore or Qt.

Because MSVC is using two different msvcrt - libraries (one release and
one debug version) you can't mix debug and release libs without a crash
sooner or later. Qt introduced the debug-prefix ('d' or '_debug') to
work around this problem and we need this for kde too. I don't know any
other way to be sure to not mix the libs... :-(

So I think Michael is using a static libxml which is wrong. Apart from this, I currently stopped msvc compilation because you can't do anything with the resulting apps (it crshes all over the time) because we mix release and debug libs.

This is the wrong question to ask. The right question is: in which *installed* file does libxml2.lib store its dependency information? Is it the lib itself?

[MSVC8] libxml2 and libiconv
Hi, for some reason I get an error each time something links to libxml2.lib, because libxml2.lib needs iconv.lib which is not linked in automatically. I think I remember someone mentioning here on the list that MSVC doesn't do this, so I think this should be fixed in the CMake files... Like, for example, checking if a test-program that links to libxml2.lib (or xml2.lib, whichever was detected) also needs to be explicitly linked to iconv.lib (or maybe libiconv.lib) --Michael ___ Kde-buildsystem mailing list Kde-buildsystem@kde.org https://mail.kde.org/mailman/listinfo/kde-buildsystem
