[lldb-dev] static fields and consts on a class

[Greg Clayton]

If you have the following code:

#include <stdio.h>
#include <stdint.h>

class A {
    public:
    static int a;
};

int A::a = 123;

int main (int argc, char const *argv[], char const *envp[])
{
    puts("hello");
    return A::a;
}



You can get to it using when running using the "frame variable" or "expression" commands:

% lldb a.out
(lldb) b main
(lldb) run
(lldb) fr var A::a
(int) A::a = 123
(lldb) expression A::a
(int) $0 = 123


You can also access it when you are not running because it is a static variable by using the "target variable" (a command that allows access to global and static variables). Since its value is stored in the data sections:

% xcrun lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) target variable A::a
(int) A::a = 123
