Re: Why is my compiler doing this????---source code for Danny Kalev

[NANOSAURUS]

Do you know an easier way to get into mode 13 if so could you please post
it.

source code:

int main(int argc, char *argv[])
{
#define uchar unsigned char

void Video::Write_DAC_C_Palette(uchar StartColor,uchar NumOfColors,uchar
*Palette)
{ outp(0x03C6,0xff); //Mask all registers so we can update any of
them
outp(0x03C8,StartColor); //1st color to input!
for(short i=0; i<NumOfColors*3; i++ )
{outp(0x03C9,Palette[i]<<2);
}
}

void Video::Set_DAC_C(uchar Color,uchar Red, uchar Green, uchar Blue)
{ outp(0x03C6,0xff); //Mask all registers even though we only need 1
of them
outp(0x03C8,Color); //Color to set
outp(0x03C9,Red);
outp(0x03C9,Green);
outp(0x03C9,Blue);
}
}

Here are the errors:28 in all

Where's the declaration of class Video? There's no declaration thereof
before main() nor is there an #include file.
Where is the #include file of the outp() function?

In short, you need to add all the missing declarations and header files
to your code. Then, if you still encounter errors, you can post them
here.
