Qt License Key Is Available
The license key is available in the Qt Account Web portal. Users with a commercial license can either sign in with their Qt account or with their Qt license key during the installation process. An offline installer is a single package that contains all of Qt and Add-Ons relevant for a target platform.
Qt Mac OS X Based On
Qt documentation says that -platform should be the host machine architecture (where you are compiling) and -xplatform should be the target platform for which you wish to deploy. However, I seem to be getting stuck with some seemingly obvious configure options for Qt: -platform and -xplatform. If you are using a binary installer or the commercial Qt Creator, your licenses are automatically fetched and stored in your local user profile (USERPROFILE\AppData\Roaming\Qt\qtlicenses.ini file).I began by installing all the mingw packages on my Fedora machine and then modifying the win32-g++ qmake.conf file to fit my environment. QtGrace is a version of Grace based on the Qt-SDK by The Qt Project QtGrace/Grace is a program to display or plot data, analyze data and prepare it for printing.Step 1: Install the License File (Commercially Licensed Qt Only) If you use Qt with a commercial license, the Qt tools look for a local license file. Native Grace for Windows, Linux and Mac OS X based on Qt. I feel like I am close, but I may have a fundamental misunderstanding of some parts of this process.Download QtGrace for free.
If you try to set the target to i686-pc-mingw32, it will show an error as MXE has removed support for MinGW.org (i.e. Static, a warning is printed because this syntax is now deprecated. If you explicitly set MXE_TARGETS to i686-w64-mingw32, omitting. At the time he wrote his answer, the default was i686-pc-mingw32, now it's i686-w64-mingw32.static.
The default package manager for Arch (Pacman) does not support installation directly from AUR, so you will need to install and use an AUR wrapper like yay or yaourt. I used Manjaro Linux.Most of the MinGW-w64 packages are not available at the official Arch repositories, but there is plenty in AUR. It does not have to be Arch Linux, derivatives will do as well. I personally find it easier than MXE and it seems to adopt newer versions of libraries faster.First, you will need an arch-based machine (virtual machine or docker container will suffice). It is easy to use and maintain, and it provides recent versions of the compiler and many libraries. Now, what you need to do is: /usr//qt/bin/qmakeIf you didn't specify MXE_TARGETS, do this: /usr/i686-w64-mingw32.static/qt/bin/qmakeUpdate: The new default is now i686-w64-mingw32.staticAnother way to cross-compile software for Windows on Linux is the MinGW-w64 toolchain on Archlinux.
Qt .Dll To Program
Adding your own libraries to the package repository (AUR) is also straightforward. I could do it in two steps:Sudo docker run -it burningdaylight/mingw-arch:qt /bin/bashThat's it! In many cases, it will be that easy. There are docker images available too.For example, let's say I want to build QNapi subtitle downloader GUI. Cmake-based projects work just as easily with x86_64-w64-mingw32-cmake.This approach worked extremely well for me, was the easiest to set-up, maintain, and extend.It also goes well with continuous integration services. For example, you will typically need to copy /usr/x86_64-w64-mingw32/lib/qt/plugins/platforms/qwindows.dll to program.exe_dir/platforms/qwindows.dll.To get a 32bit version you simply need to use i686-w64-mingw32-qmake-qt5 instead.
You can avoid that by passing the flag -skip qtactiveqt to the configure script. -xplatform win32-g++ if you're cross compiling to windows).-device-option CROSS_COMPILE=/usr/bin/x86_64-w64-mingw32-Which specifies the prefix of the toolchain I'm using, which will get prepended to 'gcc' or 'g++' in all the makefiles that are building binaries for windows.Finally, you might get problems while building icd, which apparently is something that is used to add ActiveX support to Qt. -platform linux-g++-64 if you're building on a 64-bit linux with the g++ compiler) and the target platform with -xplatform (e.g.
And there's also that problem with idc, whose workaround I've mentioned as well. But as far as I know, you wouldn't have to deal with that.3 - You can specify the cross compiler prefix in the configure command line instead of doing it in the qmake.conf file, as mentioned above. I have no idea what specs files are in the context of compilers =/. Maybe things like qconfig or qmake, but I'm not entirely sure which tools, exactly.2 - Sorry. The native compiler will be called in order to build some tools that are needed in the build process.
