Simplify my problem I put a short version of code here,
first header file:
cpp file:
my problem is I can compile them to generate .o file correctly, but whenever I link them
with other program, i got:
...multiple definition of MAX_PATH...
think hard but found no reason, anyone can help? thanks in advance.
first header file:
namespace xxx{
class util{
public:
static int MAX_PATH ;
util();
static void init();
static void do(void);
}; //end class
int util::MAX_PATH ;
}cpp file:
namespace xxx{
util::util(){
init();
}
void util::init(){
MAX_PATH = 100;
}
void do(){
//use MAX_PATH somewhere
}
}my problem is I can compile them to generate .o file correctly, but whenever I link them
with other program, i got:
...multiple definition of MAX_PATH...

Moral: don't put the definition in the header.

Thanks, actually i thought I used #ifndef so this would not be included more than
once.
for the do( ), i just use it to simplify code, more like doSomething( )
once.
