Moving "ptr=new mythread(this);" before the "connect" statement (or something similar) should do it for you. -- Eike Ziller Software Engineer Nokia, Qt Development Frameworks Phone +49 (0)30 6392 3255 Fax+49 (0)30 6392 3256 E-mail eike.zil...@nokia.com ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator

Well I think you are the first to try the cmake plugin with multiple visual studio installations. Note that the VS support for cmake is new in this 1.3 There might be a few bugs with multiple vs installations. > How do I specify the VC version to use while generating NMakefiles ? The intended way is to start Creator from a shell without a preset VS and then then the wizard which asks you to create the .cbp file should ask you which VS version it should use. I've fixed a few things which looked wrong in those code paths recently, but that's only for master. daniel ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator
[Qt-creator] Could not find mkspecs for your QMAKESPEC ?
When I run qmake in a specific project, I get this: Running build steps for project diagnosticsgui...

Error while building project diagnosticsgui When executing build step 'QMake' This is a clean development machine I just setup. I pointed Qt to the qmake to use. Other projects work fine. Where should I focus? Thanks in advance, -Ed ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator
Re: [Qt-creator] Could not find mkspecs for your QMAKESPEC ?
Never mind. I compared the bad to the working Qt project and set Qmake Build Steps project settings to the same as the working one. Sorry, I should have thought about this. -Ed On Dec 7, 2009, at 9:00 AM, Ed Sutton wrote: > When I run qmake in a specific project, I get this: > > Running build steps for project diagnosticsgui... > Starting: /opt/qtsdk-2009.05/qt/bin/qmake > /home/esutton/projects/LRADDS_BnS/proprietary/diagnosticsgui/diagnosticsgui.pro > -r CONFIG+=debug -spec ../../../../qtsdk-2009.05/qt/mkspecs/linux-g++ > Could not find mkspecs for your > QMAKESPEC(../../../../qtsdk-2009.05/qt/mkspecs/linux-g++) after trying: > /opt/qtsdk-2009.05/qt/mkspecs > Error processing project file: > /home/esutton/projects/LRADDS_BnS/proprietary/diagnosticsgui/diagnosticsgui.pro > Exited with code 3. > Error while building project diagnosticsgui > When executing build step 'QMake' > > This is a clean development machine I just setup.
