        Hi!
        I am trying to create a C function for windows in Postgres
          compiling with VC++ 2008 Express Edition. I did this function
          for Linux without problem using gcc and tried to do the same
          in Windows but in Windows was imposible. The function compile
          fine but when I tried to run from Postgres it down the server
          in windows but in Linux the same function run perfect.
      
    
    You haven't provided enough information for anyone to help you.

    
    How are you compiling your function? Using pgxs, or some other way?

    
    What's the full source code of the function?

    
    Where does the server crash when it crashes? You might need to get a
    backtrace of the server crash to help you figure out why your
    function crashes it. See this documentation on getting a backtrace
    of a Pg backend under windows:

    
    http://wiki.postgresql.org/wiki/Getting_a_stack_trace_of_a_running_PostgreSQL_backend_on_Windows

    
        The function just try to get a string value and pass to
          postgres. Reading somebody told me that I need to compile the
          function using VC++ not gcc in Windows so I downloaded VC++
          2008 Express but I dont know what directives compilation I
          need as gcc in windows and Linux.
      
    
    If you are using a standard binary distribution of PostgreSQL then
    yes, you should use Visual C++, preferably the same version of
    Visual C++ that was used for that version of PostgreSQL. Specify
    your version of Pg.
