I mean creating a project which includes several *.c source files . More than one *.c file (even each) have main( ) function.

ThanX in advance

Why do you need these multiple main() functions in one project? You can't compile them all into one binary. There can only be one main function in a program. And, in C, only one function with any given name.

Thank you for replying
but I use Standard Make C Project and
write my own makefile to resolve the problem
the C files are complied together,
because they work together,
I just want to know how to resolve it in Managed Make C Project

You may need to research this in your manual but try something like this'

Code:

#ifdef XP
     main()
     /* code for XP
#endif
#ifdef MAC
    main()
    /*code for MAC
#endif

Then let your make file tell the compiler which one to use.
As Matir has said, YOU CAN ONLY HAVE ONE MAIN FUNCTION.
So stated in The C Programming Language by Kernighan and Richie Chapter 1 Section 1.1.
It sets your entry point to the program. It can be the first function or the last function.

I don't use Eclipse so I can't answer the OP's question, but it sounds like he has a Makefile that has targets to build multiple binaries and he wants to port that into Eclipse.

In Visual Studio parlance, you would have a solution/workspace that contains multiple projects. Perhaps Eclipse has some way of grouping up several projects so that you can have them all open at once? If so, I would look into that and create a project for each binary created in your Makefile.
