pc.c(5945): warning C4013: 'pow' undefined; assuming extern returning int

[Legato]

Hey, everyone. Title says it all. Can somebody tell me why I am getting that warning?

I found BUILDIN_FUNC(pow) on script.c and couldn't find any more. Or perhaps, I wasn't search hard enough.

Can someone explain me, what does it mean, the warning. Thank you. Any help would be greatly appreciated.

Happy Holidays!

Regards,

I think that function pow is not declared and it being used in other functions so thats why it is reporting a warning. I guess that 5945 is the line number in pc.c where it is being used.

Is this an issue with the latest rAthena version (from the SVN) ?

or do you have some custom edits to /src/map/script.c that caused this?

[JayPee]

I think its not Im not getting this error also. And I found also that function in script.c. I also noticed its a Math function. maybe just try adding them.

find

BUILDIN_FUNC(sqrt)

add below the function heres the code

BUILDIN_FUNC(pow)
{
double i, a, b;
a = script_getnum(st,2);
b = script_getnum(st,3);
i = pow(a,;
script_pushint(st,(int)i);
return 0;
}

just put #include <math.h> and that should fix it. It should compile with -lm option by default anyway.

Oops this anwser is based on your title error message, if you wan't the script function then yes add JayPeeMateo snipet.

@BrianL

No, sir. It's not from rAthena's svn. I found a .patch file when I was browsing the eAthena's forum. It's a custom, yes.

But, I am using rAthena's svn.

@JayPeeMateo

I have that on script.c.

@Lighta

Sure. Thanks, would try that.

The pow script command is already in our SVN.

You don't need to do any additional edits, just checkout a clean copy from the SVN, compile, and it should work.
