@Yash001 See https://doc.qt.io/qt-5/qtquick-debugging.html "what is actual text of DQT_QML_DEBUG?" - there is no text. -DQT_QML_DEBUG sets QT_QML_DEBUG define (such defines can be checked in C/C++ code using #ifdef QT_QML_DEBUG). QT_QML_DEBUG activates "QML Debugging Infrastructure".

Few place I read, it is generated due to some issue with kernel. So I just update the Ubuntu LTS, and Now it is working with same code.

It may save other time. Call below function from installer.qs for creating *.desktop file you can call prototype by this. desktopFileCreateOnLinux() from any function in side component script. Below script will create the two place *.desktop file. inside the @TargetDir@/ inside ~/.local/share/applications/ (it will help while searching from Show application). prototype definition: Component.prototype.desktopFileCreateOnLinux = function() { if ((systemInfo.kernelType === "linux") ||(systemInfo.kernelType === "Linux")) { var dir = installer.value("TargetDir"); component.addOperation("CreateDesktopEntry", "Squidstat.desktop", "Type=Application\nName=Squidstat\nExec=\'"+dir+"/SquidStat.sh\'\nGenericName=The IDE of choice for Squidstat handle.\nIcon="+dir+"/Squidstat.png\nTerminal=false\nCategories=IDE;Qt;"); component.addOperation("CreateDesktopEntry", "@TargetDir@/Squidstat.desktop", "Type=Application\nName=Squidstat\nExec=\'"+dir+"/SquidStat.sh\'\nGenericName=The IDE of choice for Squidstat handle.\nIcon="+dir+"/Squidstat.png\nTerminal=false\nCategories=IDE;Qt;"); } }

Hi and welcome to devnet, What version of Windows are you using ? Can you run your application from the same command prompt ?

A library is not an application. If you are targeting several Linux distributions, the nicest would be to provide a package using their format e.g. .deb files for Debian based distributions. As for Windows, there's no real package format. Maybe using something like conan.io might be an option. Otherwise an archive that provides your .dll, header and .lib files for the various compilers you want to support is usually good enough. However packing a full version of all your dependencies, while it sounds nice, might prove problematic. If you provide them, then you should also take care of updating them in case of security issues found during the year.

Hi, I think you are looking for QMAKE_RPATHDIR.

@Christian-Ehrlicher said in Why it is generating multiple library files instead of single file?: why does your user has to link to all 4 files, esp. when three of them are (correct) symlinks? Sorry for silly question. I misunderstood about symbolic link. I got my answer user need to add libSquidstatLibrary.1.0.0.dylib file. Thank you.

@JonB Thank you sir, you right. I did mistake in .pro file. I mention DEFINE like below. DEFINES += WIN64 SQUIDSTATELIBRARY_LIB. To solve this error replace I replace to DEFINES += SQUIDSTATELIBRARY_LIB and it is work. I don't know some how it is work on mac, but on Linux it was giving me error. Thank you.
