Linking error
This compiles OK but the linking generates the following errors : -
--------------------Configuration: One - Win32 Debug--------------------
Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/One.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
One.exe - 2 error(s), 0 warning(s)
Code :
#include "iostream.h"
#include "allegro.h"
int main()
{
allegro_init();
install_keyboard();
//set_gfx_mode(GFX_VGA,320,200,0,0); //Remove "//" if want to use resolution: 320x200 instead of 640x480.
set_gfx_mode(GFX_AUTODETECT,640,480,0,0);
set_pallete(desktop_pallete);
textout_centre(screen, font, "Hello, World!", SCREEN_W/2, SCREEN_H/2, 255);
readkey();
return 0;
}
Any help?
Thanks

int __cdecl main ()
or go to settings menu and set __cdecl as default
calling convetion.
enjoy.

The first suggestion does not seem to work.
Still get the same error message.
Not sure where to add your second suggestion (which menu).
Forgot to mention I'm a newbee and am using VC++6
Thanks

Code:
#include "iostream.h"
should be..
Code:
#include <iostream>
using namespace std;
-
You forgot END_OF_MAIN(); at the end of main
Code:
int main()
{
return 0;
}
END_OF_MAIN();

Could you post you're entire code please?
-
This is the One.CPP file : -
#include <iostream>
using namespace std;
//#include "iostream.h"
#include "allegro.h"
int main()
//int __cdecl main ()
{
allegro_init();
install_keyboard();
//set_gfx_mode(GFX_VGA,320,200,0,0); //Remove "//" if want to use resolution: 320x200 instead of 640x480.
set_gfx_mode(GFX_AUTODETECT,640,480,0,0);
set_pallete(desktop_pallete);
textout_centre(screen, font, "Hello, World!", SCREEN_W/2, SCREEN_H/2, 255);
readkey();
return 0;
}
END_OF_MAIN();
Any help will be great. I will check the board later when I get home.
Thanks

Code:
int main()
{
allegro_init();
install_keyboard();
set_gfx_mode(GFX_AUTODETECT,640,480,0,0);
set_pallete(desktop_pallete);
textout_centre(screen, font, "Hello, World!", SCREEN_W/2, SCREEN_H/2, 255);
readkey();
return 0;
}
END_OF_MAIN();
Try compiling this
-
I added this at the front of your code : -
#include <allegro.h>
It then compiles ok but when linking gives the following error :-
--------------------Configuration: One - Win32 Debug--------------------
Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/One.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
One.exe - 2 error(s), 0 warning(s)
Any ideas here as until this is sorted I cannot do any graphics!
I assume it must be some setting in my project or VC++6 that is missing.
Thanks
Andy
