Hi, 

I'm a beginner with C++ and would like to know if there's any convienient way to
implement code on a machine running with Windows that will work on a
Unix-platform. I.e, is there any software that can help me correct my code so it
will run?

You mean the binary you produce? Or recompiling the code on every target 
platform without the need to modify the code for every target platform?

Is case of running the binary look for posix on win32 and the 
unix-flavor you use. In the other case conform stricly to the standard 
language libs.

What kind of program are you writing?

What kind of portability problem are you running against?

A few recommendations.

If you are writing software for Unix, but your development platform is 
Windows, there is an emulation layer Cygwin which allows one to compile 
and run Unix programs and libraries on Windows. However, you run into 
legal trouble if you create commercial software for Windows with it. 
There are also independant Windows ports of many typical Unix libraries, 
e.g. GTK, though they are not perfect.

winelib is an emulation of WinApi for Unix. If you already have complex 
software written which relies on Windows, this library can remedy this 
with the least effort, but it's not the recommended approach to writing 
portable software.

wxWidgets is a fairly powerful cross-platform meta-GUI library. It 
resolves to native user interface libraries on Windows and MacOS-X, and 
GTK interface on Unix. It also provides some more operating system 
abstractions and aims to be a complete application framework. It uses no 
advanced C++ features.

STL (STLport supplied for DigitalMars compilers) does not contain 
platform dependencies itself, and is available for most compilers.

STLsoft is a set of libraries which extend STL by platform-dependant and 
other features, however it makes them work on both Windows and on Unix. 
The advantage of STL and STLsoft lies in their flexibility and small 
footprint, but they rely on advanced C++ features. Besides, this will 
not give you any graphical user interface, but you can combine it with 
wxWidgets or something alike.
