I do have qt4 installed (hmm you seem to have mentioned that before) BUT that shouldn't interfere with it afaik.
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:
<quote> 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 \ -DBUILD_ALL=ON

<reply> 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 bldtrinsvn-all.sh 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.

It seems this is a case where we would need a make-conflict. but that doesn't exist in PKGBUILDs arrays. Fogobogo suggest that we add it to our make depends and require that (qt < 4).
Can we resolve this issue another way? Calvin
