extern char*, char[] doesn't compile

[robrave]

i use

Code: Select all

extern char * variablename = { "", address };

i can't see any problem with it

If the variable is global then address has to be a constant.

If not, you should post the error message.

huh?? i don't get it.. http://www.rob-soft.com/cantcompile.jpg here's the image of the code

The link to the image is dead.


I am saying that if this variable is declared outside of a function, you must use a constant value for the address.

Code: Select all

void Func() {
}

extern char * variableName = { "", 0x1005334 };

int Func1() { return 1; }

This compiles because 0x1005334 is constant. variableName is a global here.

Code: Select all

void Func() {
    DWORD dwAddress = 0x1005334;
    extern char * variableName = { "", dwAddress };
}

This compiles because variableName is a local inside a function, so the address can be either constant or variable.

Code: Select all

void Func() {
}
DWORD dwAddress = 0x1005334;
extern char * variableName = { "", dwAddress };

int Func1() { return 1; }

This does not compile because dwAddress is variable and variableName is not declared inside a function.
