Question

I have some confusions about cross compiling qt under these different circumstances:

id	build machine	target machine
1	x86_64 desktop linux	aarch64 desktop linux
2	x86_64 desktop linux	x86_64 desktop windows
3	x86_64 desktop windows	x86_64 desktop linux
4	x86_64 desktop windows	aarch64 desktop linux

The table above can be translated as "build qt-base application for <target machine> on <build machine>". And I wonder:

• how should I prepare the build toolchain on build machine?
• how should I prepare the runtime on target machine?

I would like there is an overview discussion to answer this question :) Thx.

@qqtang to correct my questions I put them in reply:

• For "build qt-base application for <target machine> on <build machine>", what should I do on both side machine?

• For “prepare qt development environment by building from source for <target machine> on <build machine>", what should I do on both side machine?
