#32472: Root compiles with qt4-mac but does not work ----------------------------------+----------------------------------------- Reporter: martin.zeman@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.0.3 Keywords: root, qtroot, qt_mac | Port: root ----------------------------------+----------------------------------------- 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:[[BR]] [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineCap: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineWidth: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineJoin: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineDash: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetStrokeColorWithColor: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetFillColorWithColor: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineCap: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineWidth: invalid context 0x0 [[BR]] Dec 9 13:23:01 valhalla root.exe[29444] <Error>: CGContextSetLineJoin: invalid context 0x0 ...[[BR]] 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: [[BR]] sudo port install python27[[BR]] sudo port select --set python python27[[BR]] sudo port install qt4-mac[[BR]] sudo port install py27-pyqt4[[BR]] sudo port install pythia[[BR]] sudo port install root +python27 +qt_mac +ssl +xml +gsl +minuit2 +tmva +roofit +pythia [[BR]] Modify .rootrc to call the QtRoot layer:[[BR]] # GUI specific settings[[BR]] Gui.Backend: qt[[BR]] Gui.Factory:qt[[BR]] # Qt GUI style setting[[BR]] Gui.Style: macintosh[[BR]] [[BR]] Call Root enviroment setup[[BR]] . /Ports/bin/thisroot.sh[[BR]] [[BR]] Start ROOT:[[BR]] root Call any Root GUI class:[[BR]] TCanvas t [[BR]] You should get the some invalid context errors.
