How to link to D Libraries in a D program

Question

I´m new to the D Programming Language and have a very simple problem.

I want to compile a D Script Library once and then use it in my other D projects.

In C I linked to the .lib files and created headers for them, but in D I don´t find things like that (are there even some sort of headers in D?)

I use D-IDE as my IDE and DMD2 as my compiler.

Answer 1

there are .di (D interface) files which can be used as header these can be generated from your sources with the -H compiler switch

however the libraries I've seen will just have the source files to import

you can use the -I switch to specify where the compiler will look for imports

and the -L switch will be passed to the linker

Answer 2

Create StaticLib.d:

module StaticLib;

int func(int x)
{
    return x+1;
}

Compile it:

dmd -lib StaticLib.d -ofStaticLib.lib

Create App.d:

module App;
import std.stdio;
import StaticLib;

void main(string[] args)
{
    writeln("func(3) = ", StaticLib.func(3));
}

Create StaticLib.di (d header):

int func(int x);

Compile it:

dmd App.d StaticLib.di StaticLib.lib -ofApp.exe
