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]]

I will attempt manual installation using the guide you linked so we can be sure whether the problem is caused by MacPorts package installation or not. I will also have a look at what I might have missed using the MacPorts package installation and report on both threads. It will take a few days ... For the record I have attempted the same using Root 5.30 and I had the same problem. It is very strange since Root runs, it even loads and opens the window (TCanvas, TBrowser), it is however missing any controls and does not respond to commands. I am using the qt_mac (not the qt x11). Also PyQt and PyRoot seem to be working for me without any issues, however it is still the X11 ROOT GUI being called, once I turn on the qt backend in .rootrc errors appear. We will see what John replies ... Cheers, Martin -- Ticket URL: <https://trac.macports.org/ticket/32472#comment:8> MacPorts <http://www.macports.org/> Ports system for Mac OS

Still I am also confused, I thought that QtRoot was incorporated into normal root distribution to be turned on by a flag during configuration. Just out of curiosity I just tried running INSTALL_QTROOT.sh and I get the following errors: cint/reflex/src/Class.cxx: In member function ‘virtual Reflex::Object Reflex::Class::CastObject(const Reflex::Type&, const Reflex::Object&) const’: cint/reflex/src/Class.cxx:98: error: ‘__dynamic_cast’ is not a member of ‘abi’ make: *** [cint/reflex/src/Class.o] Error 1 make: *** Waiting for unfinished jobs.... rm core/utils/src/RStl_tmp.cxx core/utils/src/rootcint_tmp.cxx I can try enforcing gcc46 instead of Apple compiler?

In its simplest form, MacPorts is just an automated systems for build code. In the case of root it just runs {{{ ./configure --various-options make make install }}} Of course, the devil is in the details of what options are enabled. To see this, just install the port with the -v option {{{ sudo port -v install root +qt_mac }}} Maybe something wrong can be spotted there. This just builds root against the Mac (Aqua) QT4 installation. The same one is used by a lot of ports, including an entire KDE4 ecosystem, that work fine, so I think there is most probably nothing wrong with the QT4 MacPorts provides. Personally, I'm only interested in getting QT working in the above way, with whatever comes with the root tar ball itself. If QtRoot is a separate project, someone else will have to step up and provide the Portfile for that...

The instructions you link to look rather long winded. Also it seems QtRoot is a separate project to root ? Is QT support not baked into the root code itself ?

The QtRoot support is baked into the root code for the X11 platform only. For the other platforms (Windows / Mac "native") one should use the http://root.bnl.gov/QtRoot/How2Install4Unix.html . The problem for the Mac is that I have no Mac machine myself. I can not respond quickly to the reports coming from Mac users . I have to forward it to some QtRoot Mac users and rely on their feedback and support. Another thing to consider. Due lack of demand the scope of QtRoot project was limited by the ROOT-based Qt application. I.e. the applications creating the QApplication Qt instance rather TApplication instance of ROOT. The bunch of such applications are included into the QtRoot distribution and available from http://qtroot.svn.sourceforge.net/viewvc/qtroot/trunk/qtExamples/ That means you can create the Qt application and populate your Qt GUI with ROOT TCanvas/TPad -like graphics and some other ROOT-aware GUI components from QtRootGui package (that is not a part of the root distribution) . This is what 100% of the QtRoot users want. The inverse approach is possible but it is not tested thoroughly. Roughly say, you may not add the Qt widget-based object to your ROOT GUI-based (TG-ROOT classes based ) application and I do not see anybody who wants / needs it. In the other words it is not recommended to mix Qt and ROOT GUI within one application. The code may work bit it will be not "stable " for sure. TCanvas is not regarded as ROOT GUI. Speaking ROOT GUI one means the "usual" GUI components like slider, menu, button, combo boxes etc. From this stand point it useless to test QtRoot installation using root.exe application. One should use http://root.bnl.gov/QtRoot/How2Install4Unix.html#testqtroot instead. Hope it helps.
