Root compiles with qt4-mac but does not work

[martin.zeman@…]

Dear all,

I was able to compile the root package with qt_mac variant on my qt4-mac port. However after turning on the QtRoot layer I get the following errors:

Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineCap: invalid context 0x0 
Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineWidth: invalid context 0x0 
Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineJoin: invalid context 0x0

Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineJoin: invalid context 0x0 ...

My system is Lion 10.7.2, which I assume is the problem. I tried to completely remove my MacPorts installation and do this from scratch, did not help, the problem stays the same, ROOT version is 5.32/00 (newest). Do this to completely reproduce my setup:

sudo port install python27
sudo port select --set python python27
sudo port install qt4-mac
sudo port install py27-pyqt4
sudo port install pythia
sudo port install root +python27 +qt_mac +ssl +xml +gsl +minuit2 +tmva +roofit +pythia

Modify .rootrc to call the QtRoot layer:

# GUI specific settings
Gui.Backend: qt
Gui.Factory:qt
# Qt GUI style setting
Gui.Style: macintosh

Call Root enviroment setup

. /Ports/bin/thisroot.sh

Start ROOT:

root

Call any Root GUI class:

TCanvas t

You should get the some invalid context errors. If you need me to provide anything else, please let me know.

Thanks for any help,

Martin

Apologies, there is a formatting error in the .rootrc posted here. Just put in: Gui.Backend: qt Gui.Factory:qt Gui.Style: macintosh
