Installation and Deployment

@martonmiklos said in Qt Installer Framework: Spaces in target paths (Windows7-64): @Peter.Chorn How did you managed to import the Dir component? In QIF 3 dynamic page example, there is the following definition (installscript.js): var Dir = new function () { this.toNativeSparator = function (path) { if (systemInfo.productType === "windows") return path.replace(/\//g, '\\'); return path; } };

@Wanz said in Qt vsaddin 2017 failing to create project: error dialog saying "Object reference not set to an instance of an object". Do you have VS 2017 Installed ? Is so try clearing AppData of VisualStudio ,VSCommon . Some times u can reset user data . To do that run devenv /resetuserdata.

Hello, yes I opened a new topic https://forum.qt.io/topic/99703/gdb-error-the-selected-build-of-gdb-does-not-support-python-scripting Kurt

@jsulm Thank you for clarifying this. :)

I solved the problem. Actually this is the linker error. Some required libraries were missing, so I added them as per the Readme document of the GLG toolkit(for C++). I installed the compatible GLG program and in .pro file of Qt program the library path was properly included as : INCLUDEPATH += . /opt/glg3.7/include #comment (this line includes the header files) LIBS = -L/opt/glg3.7/lib -lglg_x11 -lglg_map_stub -lXt -lX11 -ljpeg -lpng -lz -ldl -lXft -lfontconfig -lfreetype #comment (-L includes the library folder and -l include the libraries itself)

Hi @SGaist , I actually found the code I was looking for in that old QtOpenCL project you linked. Turns out to be a lot simpler than I had originally thought! Very portable too. Here it is in case anyone searches in future: glWidget->makeCurrent(); if(CGLContextObj context = CGLGetCurrentContext()) { if(CGLShareGroupObj shareGroup = CGLGetShareGroup(context)) { cl_context_properties properties[] = { CL_CONTEXT_PROPERTY_USE_CGL_SHAREGROUP_APPLE, cl_context_properties(shareGroup), 0 }; auto appleCLContext = cl::Context(CL_DEVICE_TYPE_ALL, properties); auto availableDevices = appleCLContext.getInfo<CL_CONTEXT_DEVICES>(); for(auto& d : availableDevices) { qDebug() << d.getInfo<CL_DEVICE_NAME>().c_str(); } } } NOTE: This method is specific to Apple which uses sharegroups to initialise OpenCL/OpenGL interoperability. The Windows and Linux methods are different.

QtCharts, I did qmake CONFIG+="debug_and_release build_all" and after that Qtcharts quide says I need to do make/nmake but when I did I've got the error shown in the question

Hi and welcome to devnet, You have to modify the VS2017 mkspec for that.

Hi, Boot2Qt being a commercial product, you should contact the Qt Company directly. Note that there's also Qt Functional Safety that might be of interest.

for any ubuntu 18.04 users (like me) finding this discussion through web search... don't use the ubuntu QT install from apt-get, instead install open-source-QT from the QT website. It's installer program will install binaries, including qt-for-android into it's own subdirectory.

@SGaist It worked!! 😄😄😄😄 Thanks!!! So for anyone else who stumbled here, the trick was to get this package from the Qt installer : MSVC 2017 64-bit And then go in Qt Creator, and use the aforementioned package as a "kit" to compile the project.

In the preferences, go to Build And Run, then Qt Versions. Once you added your custom Qt, create a Kit for it and you are ready to go.

@J.Hilk I was trying to add the path, but my changes weren't saving. I tried again this morning and instead of closing the terminal to see if the changes were saved, I simply attempted to use macdeployqt and it worked! Now I have other issues to deal with and I need to figure out why my changes to path aren't saving, but at least I can use the macdeloyqt tool now! Thank You! Anton Bursch

@LiDe is your issue solved? If so, please don't forget to mark your post as such! Thanks.

solved by ./configure with -qt-zlib option.

@koahnig VCLTL can let my qt program run with out VC run time VC Runtime is terrible now!

@Hank_Lee LIBS should actualy be like this: LIBS += -LPATH_TO_LIBS_DIR -lLIBA_NAME http://doc.qt.io/qt-5/qmake-variable-reference.html#libs LIBS += -L/usr/local/lib -lopencv_ \ -lopencv_highgui \ -lopencv_core \ -lopencv_imgproc \ -lopencv_imgcodecs \ -lopencv_video \ -lopencv_videoio \ ...

AFAIK, the "add" functionality only works in the Online installer.

@mzimmers On Mac "qmake" without ".exe" :-)
