I have problems with the vgakeyboard.I''m trying to make this program : #include #include #include int main() { vga_init(); keyboard_init(); while(!keyboard_keypressed(ESCAPE)) { keyboard_update(); if(keyboard_keypressed(LEFTCONTROL)) printf("LEFTCONTROL "); if(keyboard_keypressed(LEFTCONTROL))printf("RIGHCONTROL "); printf("\n"); } keyboard_close(); return(0); } This is my compile line : gcc vgakeytest.c -o vgakeytest -lvgagl -lvga This are the error''s : bash-2.03#gcc vgakeytest.c -o vgakeytest -lvgagl -lvga vgakeytest.c:In function `main'': vgakeytest.c:7: `ESCAPE'' undeclared (first use in this function) vgakeytest.c:7: (Each undeclared identifier is reported only once vgakeytest.c:7:for each function it appears in.) vgakeytest.c:11: `LEFTCONTROL'' undeclared (first use in this function) this is from a tutorial sow I don''t know what is wrong....

Any reply ? What is wrong ??????????

First of all, you should really be a little nicer, okay? It's not like you're paying us to answer your questions We're all volounteers here... You should also be a little more patient, just because someone hasn't replied to your thread in one hour doesn't mean we're ignoring you.

Have you included all of the required header files? It would also help if you told us _what_ tutorial you got that code from.

Ok , the tuturial I have is from
http://sunsite.dk/lgdc/articles.php3?mode=body&articleid=14

If you didn't notice, you lost your headers when you posted. You can use &lt; for <.

#include <iostream>

The compiler is telling you that it can't find ESCAPE or LEFTCONTROL. You have to make sure you have the libraries that define them!

Make sure you've included <vgakeyboard.h>

I have the files vgakeyboard.h vga.h and vgagl.h in my program.
Do I need other header files ?

I have tested a demo called vgakeytest.That works , so I don''t think I''m missing files.I think something is wrong with the source code.I have these header files in my code :

vgakeyboard.h
vga.h
vgagl.h

But I don''t know where ESCAPE and LEFTCONTROL are in.

I can''t find out what is wrong.Are there other tutorials for the vgakeyboard ?

Here is a working script



#include
#include
#include

int main()
{
int x;
char *keymap;

keymap = (char *) malloc( sizeof (char) * 256 );

keyboard_init(); /* this puts us in raw mode */

while( 1 ) /* an infinite loop */
{
keyboard_update(); /* get the keyboard state */

/* this way is slower than the keymap way */
if( keyboard_keypressed( SCANCODE_ESCAPE ) )
break;

if( keyboard_keypressed( SCANCODE_CURSORBLOCKUP ))
printf( "\n''UP'' was pressed\n" );

/* this loads the state into keymap */
keymap = keyboard_getstate();

/* and print out the keymap in an understandable form */
printf("These keys are pressed: ");
for (x=0 ; x<255 ; ++x )
if( keymap[ x ] == KEY_PRESSED )
printf( "%d ", x );
printf( " \r" );
}

keyboard_close(); /* this is critical! puts us back in ascii mode */
return 0;
}
