C++ qt programming, windows and linux

Question

If I write a program in C++ using Qt on windows, can I run the program on Linux (not run .exe, but use the source code)?

PS I don't mean using wine

Answer 1

If you use just the Qt framework, without any platform specific code, you will be able to compile that code on each platform. You will not, for example, be able to run the compiled binary from one platform directly on another, such as the Windows executable on Linux.
