I am writing various basic programs (sorting algorithms, trees, lists etc.) in MS Visual C++ 6.0 and need to have them compile with the GNU GCC compiler (version 2.7) of UNIX.

Are there any issues I should be aware of? Any tools that make this easy?

Thanks...

Advice no. 1 would be to stick to the standard C++, and not use any Windows specific stuff. (don't #include <windows.h>, don't use stuff like __declspec etc.)

Advice no.2, however, would be to use the standard library instead of writing your own classes - it already has sorting algorithms, lists, a binary  tree and more. For more info see http://www.research.att.com/~bs/3rd_tour2.pdf, or the following:

beware of the library, especially vector.h is not the same in different compiler (maybe because of the old version)

using namespace std;
this statement dont always work with gcc

the list, algorithm is available but if u are pratising, do it because those library or class provided has lots of redundant functions ( a tree fall in an inhabbited forrest -> it doesnt make a sound)

using iostream and stdio.h : the results may be unpredictable.

loyaliser, thanks for the points.

ahTri, I do not understand your comments about the STL. You can definitely use it with gcc. There is a very nice portable (and free) version at http://www.metabyte.com/~fbp/stl/
