[Dev-C++] Global variables (linking errors)

[Daniel G. <sp...@ho...>]

Help me out here would you? I have three C++ source files, each with its own 
header file. I want to have a global variable that all three source files 
can use.
But when I put the variable into one of the header files I get Linker 
Errors, telling me the variable has already been defined in the first of my 
source code files.

I think it's to do with the header files, but I'm not sure.

Can anyone help?

Daniel
