    Unhappy im a new coder. need compiler help!

    when i compile the code shown below i get the following errors:

    warning w8065 bomber.c 20:call to function 'sound' with no prototype in function dropbomb

    warning w8065 bomber.c 21:call to function 'delay' with no prototype in function dropbomb

    warning w8065 bomber.c 23:call to function 'nosound' with no prototype in function dropbomb

    lnk errors:

    error:unresolved external '_sound' referenced from c:\bin\bomber.obj

    error:unresolved external '_delay' referenced from c:\bin\bomber.obj

    error:unresolved external '_nosound' referenced from c:\bin\bomber.obj

    the code i used:

    #include <stdio.h>
    #include <conio.h>
    #include <dos.h>

    void dropBomb(void);

    void main()
    {
    printf("press any key to drop bomb:");
    getch();
    dropBomb();
    printf("\nyikes!\n");
    }
    void dropBomb()
    {
    int x;

    for(x=880 ; x>440 ; x-=10)
    {
    sound(x);
    delay(100);
    }
    nosound();
    }


    what could be wrong?

    Okay, the compiler errors you are getting is pretty much saying, "hey, I can't find these functions in your code or the included head files. Fix it". I don't know what else to tell you.

    Sorry, I didn't mean it like that. I was just trying to light up the room with some humor of what the compiler is thinking

    Well, I told you what I think. Try looking up something with your linker. That could be the problem. I'm not sure though. Never had much experience fooling with compilers.

    Drop Bomb Compile Problem

    Dear Slow

    I entered your code into the Borland Turbo C++ DOS compiler and compiled it without any errors. I ran the programme and pressed an S, got a long whiz sound. Nice !

    Next I loaded the code into MS C++ V6.0 Professional
    I tried to compile and got four warnings and zero errors
    c:\cprogrammes\slow.c(35) : warning C4013: 'sound' undefined; assuming extern returning int
    c:\cprogrammes\slow.c(36) : warning C4013: 'delay' undefined; assuming extern returning int
    c:\cprogrammes\slow.c(38) : warning C4013: 'nosound' undefined; assuming extern returning int
    Next I tried to execute but got four errors
    Linking...
    Slow.obj : error LNK2001: unresolved external symbol _nosound
    Slow.obj : error LNK2001: unresolved external symbol _delay
    Slow.obj : error LNK2001: unresolved external symbol _sound
    Debug/Slow.exe : fatal error LNK1120: 3 unresolved externals
    Error executing link.exe.

    My interpretation is that the compiler (Yours and C++ 6.0) does not know or use: nosound; delay; and sound, functions. Perhaps it is a compiler problem after all.

    If it is not to checky I would like to know where I can get the free Borland 5.5 compiler from. I did look at there website but could not find it.

    Good luck

    That's a good observation, but it can't be. The functions are found in the headers. You can't take away a function already defined. If you are using the same headers, than I don't know what to tell you, two.

    Drop Bomb compile Problem

    Dear Garfiled

    Thanks for your reply

    Please clarify the following: Do you mean that the three functions are known to be included the headers of the complier that Slow is using ?

    Also do you know where I can obtain a copy of the compiler Slow is using ?

    What I mean is that the linker is not recognizing the functions, therefore giving the errors.

    What compiler is slow using? I'm sure I can find a free download somewhere

    Compiler / Linker problem

    Dear Garfield and Slow

    I have a little more news

    I have downloaded the Borland command line compiler that was referred to and wrote the test programme the support material gave as an example. I compiled and ran the programme with no problems

    Next I went on to use the compiler to run C programmes I have written over a two year period for my course. Again no problems

    Next I tried Slow's programme. Alas, alack it did not compile giving the same error messages that Slow encountered.

    Next I opened C:\BORLAND\Bcc55\Include\dos.h in an editor to see if it had sound and delay listed as functions. They were not I also checked stdio.h and conio.h, but the three functions were not there either.

    Finaly, for completeness opened DOS.H, from my Borland C++ v 3 DOS IDE, into an editor and I did find delay and sound listed as functions and their suporting code.

    Unfortunately it would appear that these functions sound & delay are not supported by that version of compiler.
