1) Install LDC for Linux.

2) Download and unpack LDC for Windows somewhere.

3) Edit ldc2.conf and add this block:

	"(i686|x86_64)-.*-windows.msvc":
	{
	    switches = [
		"-defaultlib=phobos2-ldc,druntime-ldc",
		"-link-defaultlib-shared=false",
	    ];
	    lib-dirs = [
		"/path/to/ldc/ldc2-1.24.0-windows-x64/lib",
	    ];
	};

4) Compile your program with '-mtriple=x86_64-windows-msvc'.

5) Profit. ;-)

Hi Amaury! Glad to have you back!

There is this install guide [1] which has a section "Building dmd for Windows on Linux". It is a guide to install dmd for windows on linux using wine.

Cheers,

We missed you too! Good to see you back.

As for cross compiling, I've recently made some progress getting DMD to this state (Mathias has done some work on it, too) but we're not there yet.

At the moment, using a windows emulator on Linux should work.

Hey, I tried that, but I have no GUI, which the installer require. I may end up just running X on another machine and run it this way, but I was hoping for a simpler way.

You don't need an installer. Just unzip and run in place with wine. wine works fine without X running too.

Did you see the steps I posted?  No need of any GUI, just download and install LDC for Linux and download and unpack LDC for Windows (both from here: https://github.com/ldc-developers/ldc/releases -- just download the tarball/zip and unpack them, no need for any installers), edit ldc2.conf, and you can start cross-compiling right away.  It's what I've been doing for the past year for one of my projects. :-D

The LDC folk have done a really awesome job at making Linux -> Windows cross-compilation so painless.

Here's a Dockerfile that sets up everything [1]. As you can see it's quite old. This is before LDC shipped with the MinGW libraries. The Dockerfile pulls these from someone's Dropbox account [2]. This should not be necessary anymore.

Hi,
I am also trying to cross compile a windows exe from my linux host.

I tried to follow the instructions from the wiki page [0], and your instructions are basically the same.

I managed steps 1,2,3 but when compiling I get errors that the linker cannot find .lib files

$ tail -n 13 /etc/ldc2.conf

"(i686|x86_64)-.*-windows-msvc":
{
        switches = [
                "-defaultlib=phobos2-ldc,druntime-ldc",
                "-link-defaultlib-shared=false",
        ];
        lib-dirs = [
                "/home/matthew/Downloads/ldc2-1.24-0-windows-x64/lib",
        ];
};

$ cat hello.d

    return 0;
}

I have checked that the path /home/matthew/Downloads/ldc2-1.24-0-windows-x64/lib does actually contain phobos2-ldc.lib and druntime2-ldc.lib

I'm hoping there is something really obvious that I missed but I can't seem to figure it out.

Any help would be appreciated.

That's very odd.  If those files exist and your paths are correct, then it should work.  Are you sure your ldc2.conf block is correct?  You might want to try retyping the paths in ldc2.conf again manually just in case there was some copy-n-paste munging that sometimes happens.

Also, which version of LDC2 for Windows did you download?  The one I'm using is ldc2-1.24.0-windows-x64.7z (for compiling 64-bit applications; there's also an *-x86* version for compiling 32-bit Windows applications; for that you have to use a different triple and different ldc2.conf block).


Just for reference, my exact setup is:

- Download:
	https://github.com/ldc-developers/ldc/releases/download/v1.24.0/ldc2-1.24.0-linux-x86_64.tar.xz
	https://github.com/ldc-developers/ldc/releases/download/v1.24.0/ldc2-1.24.0-windows-x86.7z

- Unpack to /usr/src/d/ldc/, which should produce:

	/usr/src/d/ldc/ldc2-1.24.0-linux-x86_64/{bin,etc,import,lib,...}
	/usr/src/d/ldc/ldc2-1.24.0-windows-x64/{bin,etc,import,lib,...}

- Edit /usr/src/d/ldc/ldc2-1.24.0-linux-x86_64/etc/ldc2.conf and append
  this block:

	"(i686|x86_64)-.*-windows.msvc":
	{
	    switches = [
		"-defaultlib=phobos2-ldc,druntime-ldc",
		"-link-defaultlib-shared=false",
	    ];
	    lib-dirs = [
		"/usr/src/d/ldc/ldc2-1.24.0-windows-x64/lib",
	    ];
	};

- Then I symlink /usr/src/d/ldc/ldc2-1.24.0-linux-x86_64/bin/ldc2 to
  $HOME/bin/ldc2, and run it as:

	$HOME/bin/ldc2 -mtriple=x86_64-windows-msvc source.d -of=program.exe

  (Note that ldc2 should point to the *Linux* version of LDC2.)

  This produces program.exe which can be run with Wine or copied to a
  Windows machine and run there.

Thank you so much!

Using the two ldc extracted from the tarballs on github worked, I had ldc2 installed via pacman before, maybe something I did previously messed something up. I should probably reinstall this system at some point...
