Question Multi-Platform Development/Programming

I work in an Windows world, but live in Linux land. I'm looking at options for learning programming such that I could code once and run that program in both environments. I know Java would work, but I'm curious if there are other options.

As I understand, most libraries are OS-dependent, so if I want to code in say C++, I have to code one for Linux based on its libraries, and a separate one for Windows with its libraries/dll's. I've heard of cross-over libraries such that I can use the same source code and just compile it on the respective system, but those didn't seem to get very good reviews.

Question is then: how do people develop the various versions of their programs? For example, Mozilla has a Linux version and a Windows version. I don't see the Java Runtime Environment logo in my system tray when I'm using it, so I assume it's some other coding language. Apache/PHP/MySQL have separate versions; granted, there are no GUI to worry about, but I have to believe other libraries would create problems.

Thanks for your comments in advance.

The most common solution is to use a Multi-platform Toolkit or Library with a C or C++ program. This means the code only has to be recompiled on the platform for it to work. There are quite a few depending on the task you want.

Mozilla ( Firefox /etc..) Uses their own one, Qt is also good for this. If your thinking of OpenGL type stuff theirs GLUT or SDL. WxWindows claims to work, but I always had problems working with Windows.

If you stick with the standard libs, and mostly STL you'll probably find that it compiles well on both platforms, its when you start going graphical, or using system specific techniques ( like dll libs on windows for instance ) that you'd probably be better off with one of the above.
