Install CGAL in visual studio with error Unable to start program libCGAL-vc120-mt-gd-4.5.lib

Question

I have tried to install CGAL, maybe I installed it correctly but I don't know how to create a project Hello World in VS. When I pasted some lines of code to file .cpp CGAL project:

#include <iostream>
#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/convex_hull_2.h>
typedef CGAL::Exact_predicates_inexact_constructions_kernel K;
typedef K::Point_2 Point_2;
int main()
{
Point_2 points[5] = { Point_2(0, 0), Point_2(10, 0), Point_2(10, 10), Point_2(6, 5), Point_2(4, 1) };
Point_2 result[5];
Point_2 *ptr = CGAL::convex_hull_2(points, points + 5, result);
std::cout << ptr - result << " points on the convex hull:" << std::endl;
for (int i = 0; i < ptr - result; i++){
    std::cout << result[i] << std::endl;
}
return 0;

}

I built this code with no error, But when I ran this code in Release mode here the error: Unable to start the program :'C:\CGAL\lib\Release\libCGAL-vc120-mt-45.lib'

In Debug mode: Unable to start the program :'C:\CGAL\lib\Debug\libCGAL-vc120-mt-gd-45.lib' Please tell me how to fix it, thanks.

Answer 1

Did you successfully build the library? It is explained here in Building CGAL section. It then generates the lib files such as C:\CGAL\lib\Release\libCGAL-vc120-mt-45.lib. If it generates the .lib files with a different name (libCGAL-vc-120-mt-45.lib instead of vc120 for instance) try renaming the .lib file with the libCGAL-vc120-mt-45.lib (it worked for me).
