 |
|
I am making a little sample using GsLib and i have a problem.
First, I declare a gsDriver object :
but when i want to do something with it, the prog hangs.
For example :
| Code: |
GS.setDisplayMode(.......);
|
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: | extern "C" { void _init(void); }
int main(int argc, char **argv)
{
_init();
.
.
.
} |

Test this:
| Code: |
// outside functions (global var)
gsDriver* myGsDriver;
// in main
int main()
{
myGsDriver = new gsDriver;
myGsDriver->setDisplayMode(
....
}
// In other function
void foo()
{
myGsDriver->drawPipe.RectFlat(0,0,100,100,0,black);
}
