But libqt-mt.so and libqui.so is missing from your list! Linking fails in this case with "cannot find -lqt-mt".

KDE configure checks detect them correctly if you compile with --enable-libsuffix=64

its correct that there are no .so symlinks, they have been moved away in anticipation of Qt 4 (which now uses different so names, so they don't really conflict anymore). Anyway, I don't see an issue here. 

what I wanted to see: if you can explain what package fails in which way on x86_64, feel free to reopen :)

But we don't have special hacks in our builds and the kde configure scripts pick up libs correctly just fine. 

KDE configure checks detect them correctly if you compile with
--enable-libsuffix=64


This is my problem, it is required to pass an extra switch (be it what you said, or what I said). And why would I need such flags anyway? I install KDE in a separate dir where there is no mixage of 32 and 64 bit libraries, so the default /lib is fine for me. Or (as I said on kde-core-devel for another problem), the KDE configure should set lib64 to be the default on x86_64 without need of user intervention.

I saw first the bug when I got this x64 system, but as I was in a hurry and I upgraded the i386 version (which officially is not supported) I just fixed by hand. Now I reinstalled SUSE, and I saw that my (already configured) builds fail. 

But let's take kdetoys as an example:

For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!


In config.log:
onfigure:29754: checking for Qt

taking that
tried NO
configure:29937: rm -rf SunWS_cache; g++ -o conftest -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wconversion -Wchar-subscr

And now, with the switch of course it works:

Good - your configure finished. Start make now


So, I think it is a bug.

yes, the bug is that we have no suitable autodetection for libsuffix. but I saw that you already posted a patch upstream, and I think it correctly solves this issue. 

agree to close it as WONTFIX here and to discuss the upstream patch until inclusion?

My patch will help KDE itself, but unfortunately not all the 3rd party KDE application, unless they sync their admin dir from the KDE SVN. But if my patch goes upstream and you really think this is not a bug in SuSE, I'm not forcing to keep the bug open.

its definitely  not a suse specific problem. we can't install symlinks in /usr/lib and the configure check won't search for it in /usr/lib64. the real fix is to implement correct autochecks for libsuffix. 

though nobody prevents you to put m64 builds into /usr/lib, but that would be a too broken system to support it. 

Just to make it clear:

"we can't install symlinks in /usr/lib and the configure check won't search for it in /usr/lib64."

I wanted them in /usr/lib64 and for me the configure definitely found it.
