I am making a little sample using GsLib and i have a problem.

First, I declare a gsDriver object :

gsDriver GS;

but when i want to do something with it, the prog hangs.

For example :

Code: Select all

GS.setDisplayMode&#40;.......&#41;;

I saw that when i put the declaration inside a function, it works.

But i want to use the same gsDriver in many functions. How can I do it ?

It seems that the gsDriver is not correctly if defined outside a function.

Any idea is welocme :wink:

Just a guess, but perhaps you need to call _init at the start of your main.

Code: Select all

extern "C" &#123; void _init&#40;void&#41;; &#125;

int main&#40;int argc, char **argv&#41;
&#123;
 _init&#40;&#41;;
 .
 .
 .
&#125;

I saw that you did that for altimit but i don't understand this thing.

Can you explain me what this call does ?

Thanks

Test this:

Code: Select all

// outside functions &#40;global var&#41;
gsDriver* myGsDriver;

// in main
int main&#40;&#41;
&#123;
	myGsDriver = new gsDriver;
	myGsDriver->setDisplayMode&#40;
	....
&#125;

// In other function
void foo&#40;&#41;
&#123;
	myGsDriver->drawPipe.RectFlat&#40;0,0,100,100,0,black&#41;;
&#125;
