gdb Could not find operator

gdb Could not find operator

double var1, var2;
std::vector<double *> x;

var1 = 1;
var2 = 2;

x.push_back(&var1);
x.push_back(&var2);

When I debug this code in gdb and try print x[0] or *x[0] I get:

Could not find operator[].

My understanding is that the compiler/linker includes only the member functions present in the source code and those are the ones I can use in gdb.

Your understanding is incorrect / incomplete.

std::vector is a template class. Without explicit instantiation, the compiler is required to instantiate only the methods called (usually a subset of methods present in the source).

Is there a way to include every member function of std::vector so I can access them in gdb?

For a given type T, you should be able to explicitly instantiate entire vector for that T, by requesting it, e.g.:

template class std::vector<double>;

Try print by inner member of the vector.

print *(x._M_impl._M_start+0) 

Here 0 is the index of data you want to inspect.
