    Linker error

    I have included a header file in my c-file, laying in the same folder. The header file refers to a function in another c-file, also in the same folder. But when I try to call that function it is not found, it says "undefined reference to ...". How do I do to make my compiler find the function? Why shouldn't I just include the other c-file in my first c-file as well as the header file? Wouldn't it be like splitting up a large c-file into a couple of smaller files?

    I am using WinXP and DevCpp.

    You add both source files to your project.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Hmm, post some code, it will be easier to find the solution with some solid code.

    On a side note, did you set the program up as a "project"? If not, you will not be able to link the files together anyway
