Hi,
I'm having some problems with gcc 3.2 and __attribute__((deprecated))
when used in combination with inline functions. I need to add the
attribute to quite a few methods in several classes. These deprecated
methods are implemented inline, as in this example:
class X {
public:
X() {}
void foo() {}
};
But this doesn't compile ("parse error before `{' token"):
class X {
public:
X() __attribute__((deprecated)) {}
void foo() __attribute__((deprecated)) {}
};
I found that this works:
class X {
public:
__attribute__((deprecated)) void foo() {}
};
but I didn't find such use of __attribute__ in gcc documentation, so
I'm not sure it will continue to work in future gcc versions. More
importantly, it doesn't work with constructors, this doesn't compile:
class X {
public:
__attribute__((deprecated)) X() {}
};
The only working solution I found so far is to move the implementation
outside of class { ... } statement:
class X {
public:
X() __attribute__((deprecated));
void foo() __attribute__((deprecated));
};
inline X::X() {}
inline void X::foo() {}
But I'd like to avoid it if possible both because of the amount of
deprecated methods and because inline implementation at the line
pointed to by gcc warning serves as a hint how to fix code that uses
deprecated calls.
Is there some way to do what I'm trying to?
Thanks!
