Oh yes it will :(

  There are several problems, see thread:

[trinity-users] kdebase make failure if Qt4 installed, QtCore/qfile.h
QT_BEGIN_HEADER doesn't name type

There are 2 big ones, cmake will not ignore Qt4 uic and end up trying to use it
instead of uic from trinity. (you can try and trick it by putting
/opt/qt/bin:/opt/trinity/bin/ before /usr in your path, but that is a risky hack.

Then there is:

If kde4/Qt4 is installed, cmake fails when it uses
/usr/include/QtCore/qfile.h instead of /opt/qt/include/qfile.h.

I cannot figure out how to tell cmake to ignore the /usr/include. I have tried
the cmake arguments:

  cmake ../ \
    -DCMAKE_INSTALL_PREFIX=${trinity_prefix} \
    -DWITH_QT3=ON \
    -DQTDIR=/opt/qt \

They are right, some KDE3 applications where no amount of
configuration helps only build properly in a clean chroot, without the
KDE4 stuff around.


So even though you can *INSTALL* Trinity next to kde4, that doesn't mean you can
*BUILD* Trinity next to kde4 :) Same goes for Qt4. If you are building trinity
based on Qt3, just because you can *INSTALL* a Qt3 based Trinity on a system
with Qt4 present, it doesn't mean you can *BUILD* a Qt3 based Trinity with Qt4
present :)

The PKGBUILD files are correct, but they don't work magic :p

Set up a clean build environment in VirtualBox. Alocate  ~15G to the install,
(you could probably get away with 8G total). For a 15G VM allocate 5G '/', 120M
'/boot', the rest '/home'. The basic Arch install takes ~ 10 minutes to install
base and base-devel packages and all you have to do is hit 'return' and the Arch
defaults for partitioning, etc. are fine.

Then what I did was just to setup my existing /home/david dir as a shared folder
in VirtualBox to provide access to all my files and provide a place to save
finished packages so they exist outside the VM. Then in the VirtualBox guest
install of Arch, just create your /home/calvin/builds, set the paths for the to use that as your builds dir and point the srcdir and pkgdir
path to the shared folder on your original /home/calvin that you shared with
your guest as something like 'hhome' (short for host home) and start building.

No whacky kde4/kde3 lib conflicts and no Qt4/Qt3 header file conflicts.

Some software just needs a clean build environment to build properly. It has
nothing to do with running it, it just has to build without the presents of
conflicting files.
