Reading Visibility in the GNU wiki, it is clear.
Taking this example from C++ Tutorials
// classes example
#include <iostream>
using namespace std;
class Rectangle {
int width, height;
public:
void set_values (int,int);
int area() {return width*height;}
};
void Rectangle::set_values (int x, int y) {
width = x;
height = y;
}
Is it possible to make area() public and set_values(int,int) local as shown in the first link without altering the code?
I wrote my makefile to get the .so
someproj.so : someproj.cpp
g++ --std=c++11 -O3 -fPIC -shared someproj.cpp -o someproj.so
Modified to make all symbols hidden by adding -fvisibility=hidden
someproj.so : someproj.cpp
g++ --std=c++11 -O3 -fvisibility=hidden -fPIC -shared someproj.cpp -o someproj.so
Is it possible to customized which functions are exposed by modifying the compilation command above?
Currently using 4.7.2 version of gcc
