Would statically compiled by the system of environmental impact, such as I am on the same architecture arm64 operating system on A compiled, can be directly to the operating system used on B

CodePudding user response:

Can certainly, premise is you qt5 program and don't put a piece of qt4

CodePudding user response:

can certainly, premise is you qt5 program and don't put a piece of qt4
