    Question How do I know which function requires a '-lsomething'?

    Dear all,


    If I use the math functions like 'sqrt', I need to compile with '-lm'.
    However, for example, using the function 'socket', does not require '-lanything'.

    So, how do I know which function requires a '-lsomething', before I get compiler error message? Is there any guides on that?


    Thanks in advance!
    Michael

    Your local documentation is about all there is to go on I'm afraid.

    There is "common practice" for some things, but each implementation can package functions into libraries in many different ways.
    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.
