    Cygwin Help

    Hello, i am new to programming.
    I know a little bit of C and am trying to learn pascal.
    I have Cygwin On my computer, and i used to use it to program for psp.
    The Cygwin Dash Barely notices any code, it notices some C and zer Pascal.
    For Example:
    Code:
    Craig@computer ~
    $ #include <stdio.h>
    
    Craig@computer ~
    $
    
    Craig@computer ~
    $ main(){
    > POINT pt;
    > getcursorpos(&pt);
    bash: syntax error near unexpected token `&'
    
    Craig@computer ~
    $ }
    Also, it doesnt recognize variables like 'int' type as it reads:
    "bash: syntax error near unexpected token 'int'"

    I think What I need is some libraries, so if somebody could point me to some libraries for both C and Pascal, and tell me where to save them under cygwin, i would be very appreciative. Thank You.

    Oh, and By the way, i am on Windows XP professional if that matters.

    Presumably you're using bash, which speaks bash not C.

    > I think What I need is some libraries
    Or a text editor and a C compiler...

    I used to use cygwin to compile PSP programs that i wrote in C.
    That was using psptoolchain. So ur saying i should get a comiler and text editor?
    Ive thought of taht before, but ive used cygwin to compile before, so i thought id use that. I have to try and find out the administration password, cause there is always sumthing going wrong when i try to download on this user. Ive actually tried to get crimson editor, which is what i used when i was doing psp. Thanks for the help, ima go mess around with it for a bit
    =p


    EDIT:
    Ok, i got a compiler(Bloodshed Dev-C++), it seems that my simple program wont show me the cordonites of the screen, it looks like a window pops up, but it shutsdown rightaway.
    Code:
    #include <windows.h>
    
    main(){
           POINT pt;
           GetCursorPos(&pt);
           }
    it comiled with no errors, but could somebody help me. The program is just to find the coordinates of the cursor on screen. Thank you.

    Read the FAQ concerning How do I Stop my Windows Console from disappearing everytime I run my program?

    Actually, in view that maintenance on Dev-C++ has stopped yet the program still has a number of bugs, it would be better to use Code::Blocks or Microsoft Visual Studio 2008 Express.

    Thank you guys a bunch, i finally got this working, i had to use cygwin to run the compiled code, and here it is:
    Code:
    #include <stdio.h>
    #include <windows.h>
    
    main(){
           POINT pt;
           GetCursorPos(&pt);
      printf("%pt"); //Added this cause the program had no output =P
           }
    And when i ran the program on cygwin:

    Code:
    Craig@computer ~
    $ ls
     getcursorpos  helloworld
         
    Craig@computer ~
    $ cd getcursorpos
    
    Craig@computer ~/getcursorpos
    $ ls
    getcursorpos.exe
    
    Craig@computer ~/getcursorpos
    $ ./getcursorpos.exe
    003E2478t
    Craig@computer ~/getcursorpos
    $
    so the output is "003E2478t". How do i get this into x,y coordinates?

    Lolz, yeah, i shoulda checked it up, all i remembered from psp programming was that there was a % in it. Isnt it wierd that it still comiled with no errors?

    I redid my code to this:

    Code:
    #include <stdio.h>
    #include <windows.h>
    
    main(){
           POINT pt;
           GetCursorPos(&pt);
           printf("%p",pt);
           }
    And cygwin outputed this:
    000000C5

    What does this mean!!?? is it like the address of that pixel? How do i get it into x,y format(i need x,y for pascal!);

    The Windows POINT is a structure that contains two members, x and y, which means you're going to have to print them out yourself.

    Code:
    printf("(%ld, %ld)\n", pt.x, pt.y);
    As for the other, gcc will tell you
    Code:
    warning: too few arguments for format
    provided you don't silence the warnings.

    Again, %p prints pointers.
    You need something like
    printf( "%d %d", pt.x, pt.y );

    But you need to research the names and types of the struct members, and the associated printf format strings.
    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.
