在Linux上编译Windows屏保

Question

an customer would like to provide to his website visitors an windows screensaver as download. So far so god, but: The screensavers should be generated on the fly with some meta date which needs to be displayed within the screensaver.

I've found some windows tools which can create screensaver files through an UI (http://www.instantstorm.com/download/) but they provide no documented cli interface if neither. The cli interface could be useful when using DOSBox on ubuntu to compile an screensaver file.

The question is how this could be accomplished?

Answer 1

如果它是最新的Windows应用程序，则可能需要使用wine而不是dosbox ，如果它是cli应用程序，则实际上并不需要X。

Answer 2

是的，您可以在Linux上编译Windows二进制文件，但是除非您提供更多信息，否则无法提供更多详细信息。

Answer 3

You should be able to use mingw32 to cross compile executables for windows, though you will need to make your sources acceptable to GCC in order to do this.

However, have you considered the possibility of patching the binary rather than compiling it? Perhaps things have changed since I last tried it under XP, but I believe strings included in the program or in a resource come through either unchanged or in an accessible encoding which you could easily patch, provided that you kept the length in memory the same (for something null-terminated, you can always make it shorter by placing a null earlier). Also you might be able to append data to the end of the executable and read that at runtime.

However, if your binary is expected to be signed in some manner, you'd have to do the signing after the modification.
