it looks as if "pkg-config" can't be found in your system, or isn't 
configured properly. Please run "scons" on the following simple SConstruct:

env = Environment(tools=['default','qt4'])
env.EnableQt4Modules(['QtCore','QtGui'])

print env.subst('$CPPPATH')



It should print the include paths for the Qt modules like 
"/usr/include/qt4 /usr/include/qt4/QtCore /usr/include/qt4/QtGui". If 
this doesn't happen, check that you have pkg-config (`which pkg-config`) 
and that you have the "libqt4-dev" package installed.

The "rcc" executable supports the "-root <path>" parameter, that you can 
set via the $QT4_QRCFLAGS variable. Please check "rcc -?" for how this 
option works exactly.

The "automoc" feature assumes that your *.h files are next to the CPP 
files. You can't change anything about this, but you could use the 
explicit MOC builder named ExplicitMoc4() instead.

Hope this helps.

Best regards,

Dirk
