That worked like a charm. Now I can use dlang confidently. Any tips to make it faster cflags etc.

There's actually a variant of this sample that is run as a test from the dmd compiler testsuite, so it is checked hundreds of times a day for pending pull requests, on all officially supported platforms by the auto-tester: https://auto-tester.puremagic.com/pulls.ghtml?projectid=1 https://github.com/dlang/dmd/blob/master/test/runnable/extra-files/cppb.cpp#L41 https://github.com/dlang/dmd/blob/master/test/runnable/cppa.d#L25 Looking at the D script that runs each compiler test, it adds the following flag for all C++ objects: https://github.com/dlang/dmd/blob/master/test/d_do_test.d#L499 So adding that flag got your example to work for me: dmd -L-lstdc++ foo.d Sample.o

On my system, it appears to be -lc++. So in order to pass this value to the linker, use the dmd parameter -L-lc++ In order to find out what the name of the c++ library is, you need to compile a C++ program with the -v option. The linker step will show the library parameters you need to send to dmd. -Steve

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
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:

The D Programming Language is a great book. If you are a university student you'll probably be able to read it for free. I finally got my hard-copy, and it's great.
