SYMPTOMS
Using a typedef cast in the member initialization of a class may cause the following errors:
RESOLUTION
Use the actual type rather then the typedef. For example, in the following sample use test::run rather than test_run. Or, use the functional notation test_run (arg) for type conversion instead of the cast notation. Another option is to initialize the member in the body of function.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was corrected in Microsoft Visual C++ version 6.0.
MORE INFORMATION
/* Compiler Options Needed : none */
class test {
public:
enum run{ one, two, three };
};
typedef test::run test_run;
class test2 {
test2(int);
~test2();
public:
test_run testvalue;
};
test2::test2(int arg):testvalue( (test_run) arg) {} //Causes error
// test2::test2(int arg):testvalue( (test::run) arg) {} //WORKAROUND 1
// test2::test2(int arg):testvalue( test_run (arg)) {} //WORKAROUND 2
