I've tried installing the recently release version and am coming up against the same probs as before:

here is my installation method (Kubuntu)

tar -xzvf php-qt-0.1.tar.gz
cd php_qt
mkdir build
cd build (If I don't do this cmake .. fails)
cmake -DQT_INCLUDE_DIR=/usr/share/qt4/include -DQT_QMAKE_EXECUTABLE=/usr/share/qt4/bin/qmake ..
sudo make install

which produces this output:
$ sudo make install

[ 73%] Built target smokeqt
[100%] Built target php_qt
Linking CXX shared library CMakeFiles/CMakeRelink.dir/libsmokeqt.so
Linking CXX shared library CMakeFiles/CMakeRelink.dir/php_qt.so
Install the project...

-- Install configuration: ""
-- Installing /usr/lib/php5/20060613+lfs/php_qt.so

I've copied the tests from the site:
test 1 runs ok, all other tests either seg fault:
$ php t3.php
Segmentation fault (core dumped)

or produce this PHP error:
$ php t2b.php

Fatal error: Undefined class constant 'Bold' in /foo/php_qt_tests/t2b.php on line 20

here is the install manifest

I had to symlink /usr/lib/libsmokeqt.so.2 to /usr/local/lib/libsmokeqt.so.2

Can anyone help?
