how to corss compile for windows in Linux

[e8johan]

As long as you stick to Qt, none. There can be issues with filenames (drives, / or \, etc), header files, focusing on advanced pop-ups (such as IntelliType), but a normal app should be portable as it is.

I compiled it on windows, I have appropriate changes in make file (I changed path ). and compile. Copmiler shows followin error.

Don't edit the Makefile --- just generate a new one from the .pro file.
