The same goes for kdeartwork
it seems kvirc is affected by it too.

mark, what use flags, cflags, chost, cxxflags do you have?
mark, also run this script: #!/bin/bash for i in /usr/lib/*.so /usr/bin/* /usr/sbin/* do ldd ${i} 2>&1 |grep "not found" - >/dev/null && qpkg -f -nc -v $i ; done |sort |uniq | while read PACK ; do emerge -p \=${PACK}; done and let me know which packages it reports.

*** Bug 4664 has been marked as a duplicate of this bug. ***
I have tried isolating the bug in ./configure. See attached tgz-file for a small example. The only change between working and non-working is '-3.2'.
Created attachment 3475 [details] testcase from ./configure
Using the files from test.tgz: This works: g++ -o conftest -I/usr/qt/3/include conftest.cc -L/usr/qt/3/lib -lqt-mt This does not: g++-3.2 -o conftest -I/usr/qt/3/include conftest.cc -L/usr/qt/3/lib -lqt-mt
I am getting closer still. conftest.cc can be shortened to: #include <qcursor.h> #include <qstylefactory.h> int main() { (void)QStyleFactory::create(QString::null); QCursor c(Qt::WhatsThisCursor); return 0; } Works: # g++ -c -I/usr/qt/3/include conftest.cc -L/usr/qt/3/lib # g++ conftest.o -o conftest -lqt-mt -L/usr/qt/3/lib # g++-3.2 -c -I/usr/qt/3/include conftest.cc -L/usr/qt/3/lib Does not work: # g++-3.2 conftest.o -o conftest -lqt-mt -L/usr/qt/3/lib Somehow it seems the 3.2 linker will not look for qt-mt in /usr/qt/3/lib A wild guess: Problems with the ABI between difference gcc-version? Maybe it could be solved by recompiling qt with gcc-3.2. Will try that now.
It will not work, I've tried that already.
Phew this was a tough one: The problem was indeed that the Qt library was compiled with gcc-2.x. But to compile Qt with gcc-3.2 it is not enough just to alter make.conf (see bug 7117). You will have to make sure that /usr/bin/gcc and /usr/bin/g++ are in fact g??-3.2. So the workaround is: cd /usr/bin mv gcc gcc-2 mv g++ g++-2 mv gcc-3.2 gcc mv g++-3.2 g++ emerge qt emerge arts Can others confirm that this works?
I can confirm it *doesn't* work.
What error do you get? Something like: relocation error: /usr/lib/libkvilib.so.3: undefined symbol: __ti7QPixmap ? Did you remember to recompile all depending libraries (i.e. most KDE-stuff) with gcc-3.2?
It seems you need to recompile _alot_. If A depends on B and C, and D depends on C, and B must be recompiled, then both A, C and D must also be recompiled. So while I _can_ get artsd to work, I break alot of other packages (Think of glibc being C in the above). Having some programs compiled with gcc-3.2 on the same machine as some programs compiled with gcc-2.x seems to be troublesome. If we upgrade everything to gcc-3.2 it would probably solve most problems. However, some non-free software may break.
I re-emerged *everything* this night, with gcc 3.2-rc1, but still kdeaddons fails. The output is still the same as I have attached in here august 26th. Mark.
100% sure I found the error: it has something to do with a strange reference to something called libstdc++-libc6.2-2.so.3 !!! Mark
...and after a little research I found out that is a part of gcc. This is way out of my league but this is a good place to search / read: http://gcc.gnu.org/libstdc++/
removed dependency with bug 7117 - it doesn't seem like this isn't the problem for this bug.
http://www.gentoo.org/~carpaski/system_update/ - gcc upgrade instructions and helper scripts. HTH...
Mark: which gcc do you have installed? maybe you have multiple versions, please post the output of emerge -s gcc. All: Is this bug fixed for you?
Hi Hannes, I have performed a fresh installation of Gentoo and the problem did not occur again. Thus as far as I am concerned, this bug may be closed (it went dead).
ok, closing this bug.
