Examine boost shared_ptr with gdb
boost, c++, gdb, shared-ptr
Solution
Got it.!
(gdb) set print pretty
(gdb) p obj
$5 = {
px = 0x602010,
pn = {
pi_ = 0x602030
}
}
(gdb) p obj.px
$6 = (MyClass *) 0x602010
(gdb) p *(obj.px)
$7 = {
i = 10
}
Problem
Following is my source code: ``` #include <iostream> #include <boost/shared_ptr.hpp> class MyClass { public: MyClass() { i=10; } private: int i; }; int main(int argc, const char *argv[]) { boost::shared_ptr <MyClass> obj(new MyClass()); return 0; } ``` I want to examine obj in gdb, and view the value of member variable i. This is what I get with normal print: ``` 29 boost::shared_ptr <MyClass> obj(new MyClass()); (gdb) n 30 return 0; (gdb) p obj $1 = {px = 0x602010, pn = {pi_ = 0x602030}} ``` I tried the tip mentioned in this link , but does not work. ``` (gdb) call (obj.get())->print() Cannot evaluate function -- may be inlined ``` Is there any other way? gdb version is 7.0.1.
