    VS2005 to gcc

    Hi, I have a simple C++ source file which works perfectly in Visual
    Studio 2005. Unfortunately I have to get it compiled for use on a
    remote linux machine. Using putty I get a zillion cryptic error
    messages that scroll off the putty screen making it impossible to see
    the first error messages. Is there a way to compile Linux executables
    on Windows or somehow get a more forgiving Linux compiler or a page
    with all the nonos in gcc that are acceptable in VS?

    edit when I use g++ instead of gcc all I get is an a.out file

    The a.out file is an executable and means that your code compiled correctly. You can specify the output binary file using the '-o' flag, i.e. 'g++ -o myprogram main.cpp'.

    Edit: gcc compiles your code as C by default, whereas g++ is the C++ compiler, which is why it worked under g++ but not gcc.

    When you compile on the remote machine, do this
    gcc prog.c 2>errors.txt

    Then you can transfer all the errors back to your machine to see what you did wrong.
    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.

    The big question is, as already pointed out, why are you trying to compile your C++ code with a C compiler (gcc)?

    You need to use g++.

    In order to run the a.out file that was generated by g++, or whatever you called your executable, use "./a.out" (or whatever).

    [edit] g++ is the C++ compiler that is still part of the GNU Compiler Collection (GCC). [/edit]

    Yes of course. I was referring to the actual command.

    Comments like these illustrate why you should understand what you're even doing before you run into it wildly.
