I am aware about how to add compiler in Qt Creator. However my Qt always chooses MSVC compiler. How to set MinGW (built-in or external) instead of MSVC?
Couldn't find any post which can help a newbie to know how to change the compiler of desired preference. My current system is Windows, however information on Linux (g++ <--> clang++) is also welcome.

Following is the way with Qt 5.9:
- While configuring a new project, select only those compilers/kits which are required;
- For 64-bit system, get the latest MinGW and install in a suitable path; While installing MinGW64, you may select "posix threads", and not "win32 threads" to allow threading related libraries
- Go to
Tools > Options > Build & Run > Compilersand add a manual C++ compiler. Choose the path of where you installedC:/MinGW64/bin/g++.exe(name it something like "MinGW64"); Similarly you may add C compiler as well withC:/MinGW64/bin/gcc.exe; Click 'Apply' - In the same dialog box, select the
Debuggerstab and similarly addC:/MinGW64/bin/gdb.exe(name it like "MinGW64 Debugger); Click 'Apply' - In the same dialog box, select the
Qt Versionsand add a new Kit withMinGW64like name; However I couldn't find an appropriateqmake.exefor it; Hence, I decided to use the sameqmake.exe, which came with built-in 32 bit MinGW within Qt package (not sure about this as of now) - In the same dialog box, now select the
Kitstab and add a newManual kit; You may also follow the way the default MinGW32 bit compiler is configured; ConfigureCompiler,DebuggerandQt Versionfor this newly named kit; Click 'Ok' - On the left pan of Qt creator, click on "Projects" tab, and go to "Build & Run" option there; To avoid confusion, you may disable all the kits which are not required; Just keep the relevant kit and click "Build" with either "Debug" or "Release" setting
