Hi,

Just started to work with D. Great language.

I want to use C++ libraries for machine learning and deep learning. How do I add C++ libraries to my d code.

For example,

//sample.cpp
#include <iostream>

using namespace std;

int foo(int i, int j, int k)
{
    cout << "i = " << i << endl;
    cout << "j = " << j << endl;
    cout << "k = " << k << endl;

    return 7;
}


//foo.d
extern (C++) int foo(int i, int j, int k);

void main()
{
        foo(1,2,3);
}


How do I compile and link each of them to produce the result?
dmd -c foo.d
gcc -c Sample.cpp

Both of them get me .o files. Where do I go from there?

Thanks,
Siv

This should work:

dmd foo.d Sample.o

Just like the C examples from the D blog:
