hi,

i have kde4.2svn lnstalled, but ktorrent is not compiling after some kde 4.2 changes. ktorrent 3.1.1 was not compiling the problem seems to be with cmake unable to find kde4.2svn's automoc4. I even installed automoc4 in /usr but still it fails.

---------------------------------------------
root@superb:~/build/ktorrent# which automoc4
/opt/kde/bin/automoc4
----------------------------------------------
root@superb:~/build/ktorrent# automoc4 --version
automoc4 0.9.87
----------------------------------------------

Even ktorrent 3.1.2 is not compiling, because cmake can't find the installed automoc4 which is in /opt/kde.

here's the cmake output:
root@superb:~/build/ktorrent# cmake /root/ktorrent-3.1.2/

-- Configuring done

It was ktorrents' cmake trying to find automoc4 at /usr not at kdesupport's installed directory /opt/kde (which was in the path, of course)

Solution:

ln -sf /opt/kde/bin/automoc4 /usr/bin

and compile ktorrent

cd ktorrent
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/opt/kde
make
make install

works! thanks.
