[Qt-interest] Building QT under from linux using MingW

[Stephan Rose]

*smack self*

Thanks...I completely didn't even think about that...

 stephan at software:~$ ls /usr/i586-mingw32msvc/include | grep windows.h
windows.h

Theres your problem, it's windows.h, not Windows.h - case sensitivity in Linux.

Could
$cp windows.h Windows.h or create a symbol link as a dirty fix.

It's called cross-compiling. It works, usually. How do you think I write software for embedded ARM or Motorola devices? They also use gcc, but of course a version of gcc that targets those devices. The same goes for MingW, it targets windows but the host is linux. Nothing wrong with that.

And as for the reason why, this is why:

Current steps to build a windows version of my QT app:

1. Check in changes to SVN
2. Reboot into windows
3. Get latest changes from SVN in windows
4. Build
5. Reboot into linux
6. Deploy updated executable on update server

If I can cross-compile to MingW from linux, my steps would look like this:

1. Check in changes to SVN
2. Build mingw version
3. Deploy updated executable on update server

Yes it exists on the system. mingw exists under linux for cross-compiling purposes and comes with all necessary headers and libs.

stephan at software:~$ ls /usr/i586-mingw32msvc/include | grep windows.h
windows.h

There you go.
