There's one other gotcha to bear in mind when using external libraries: if the library contains a ``main()`` function, then this - will be linked in preference to GHC's own ``main()`` function (eg. - ``libf2c`` and ``libl`` have their own ``main()``\ s). This is - because GHC's ``main()`` comes from the ``HSrts`` library, which is - normally included *after* all the other libraries on the linker's - command line. To force GHC's ``main()`` to be used in preference to - any other ``main()``\ s from external libraries, just add the option - ``-lHSrts`` before any other libraries on the command line. + will be a link conflict with GHC's own ``main()`` function (eg. + ``libf2c`` and ``libl`` have their own ``main()``\ s). + + You can use an external main function if you initialize the RTS manually + and pass ``-no-hs-main``.
