Hey fellas'. I'm new to using gcc and am just wondering what might have cause this error in my game? I'm not too sure what this means or how to fix it so if you can help it'll be appreciated thanks.

It's a syntax error. That's about all anybody can tell you unless you post the erroneous portion of your code.

typedef struct Balls
{
int xVelocity;
int yVelocity;
u8 xMax;//240 - xMin
u8 yMax;//160 - yMin
u8 xMin;
u8 yMin;
u16 xball;//30
u16 yball;//15
}ball;
ball Ball;
Ball.xVelocity = 4;
Ball.yVelocity = 2;
Ball.xMax = 232;
Ball.yMax = 152;
Ball.xMin = 8;
Ball.yMin = 8;
Ball.xball = 30;
Ball.yball = 15;

It compiled fine for me. I had to add type definitions for u8 and u16, and put the code into a function to get it to compile.

hey, what version of gcc are you using?
I'm using the version that comes with devkitadv

well i dun' know, you say the code worked in your function, why the heck is it not working for me. I read on some site i found off google that those parse errors happened with older gcc versions and not with newer ones
, hmmm..

Parse errors happen because of syntax errors in your code, irrespective of what version of GCC you are running. Getting a newer version of GCC will not fix your code.
It is highly irregular to have a struct declaration in such close proximity to executable code. Are you sure you haven't declared a function somewhere?
The compiler should say what line number of what file the error occurred in. That is where you should look.
It's a guess, but based on the type of parse error, I'm guessing you've forgotten a semicolon somewhere.

Er... actually... I'd guess there's no main() function. Unless I miss my guess, the assignments to Ball.whatever are taking place outside any function, which might be legal in Javascript, but is a no-no in C. Try this:
| Code: |
typedef struct {
int xVelocity;
int yVelocity;
u8 xMax;//240 - xMin
u8 yMax;//160 - yMin
u8 xMin;
u8 yMin;
u16 xball;//30
u16 yball;//15
} ball;
ball Ball;
void SetupBall(void)
{
Ball.xVelocity = 4;
Ball.yVelocity = 2;
Ball.xMax = 232;
Ball.yMax = 152;
Ball.xMin = 8;
Ball.yMin = 8;
Ball.xball = 30;
Ball.yball = 15;
}
|
Be sure to call SetupBall() at some point, or it'll never happen ;)
Note how I removed the initial "Balls" structure type name. You don't need it, since you're typedefing "ball" to be that type anyway.
