I have written a C++ program in windows and it fails to work on linux

I have wriiten a program in windows using C++ and Qt as a GUI helper my problem exists when i copy my compiled files across to linux using a USB storage device linux wont recognise my main.o file is that just because i need to recompile it on linux before i attempt to run it. I get a binary failure. Is this because im too lazy to download the compiler that works with Qt on linux or is it a more serious error with my program?

Nailed it right there my friend

On a less frivilous note, though, yes, you would need to recompile it for Linux.

The standard compiler on linux should not have an issue with qt. In order to compile thing that depend on other libs (QT for example) you need the -devel version of the package (qt-devel in this case). This example is how RH based systems work, but other distros usually follow a similar pattern.

There you are the basic idea.

As for the other issue, Windows and Linux are *incompatible* at binary level, just like you can't run a Windows program on MacOSX or in a PlayStation. You might want to try to run your program under Wine, though. It's a little toy that will let you run some programs compiled for Windows under Linux. The key word is "some".
