I am getting very strange bug on very simple project. Here is sources http://rgho.st/7j5LQLZxb (blue button for downloading).

On: dub build I am getting error:

Unexpected OPTLINK Termination at EIP=0040F60A
EAX=03930000 EBX=00438C70 ECX=00000EE6 EDX=000002CE
ESI=00000104 EDI=03930468 EBP=0019FF38 ESP=0019FEF0
First=00402000

on: dub build --compiler=ldc2
It's buildable, but I am getting error on execution. The error says that file is corrupted.

If comment mysql driver. database.d:

import std.stdio;
import std.string;
import core.thread;
import ddb.postgres;
// import mysql; // <-- here
import vibe.d;
import config;

the project begin buildable with dmd and ldc2 and run ok.

I haven't seen such error before. I tried to clean

>link
OPTLINK (R) for Win32  Release 8.00.17

>DMD32 D Compiler v2.074.0
But I tested it on 2.073.0 too

Also I tried to cleanup folder:
AppData\Roaming\dub

but it did not help :(

Any ideas?

Windows 10

> But I tested it on 2.073.0 too
Not 2.073.0 but v2.073.2

I checked v2.073.1 too and he reported that it's buildable with v2.073.1 on his PC.

Any ideas?

I checked all possible combination of dmd and vibed (0.7.30 brunch). No result. Only a little bit another error:

I can build project only in release mode with:
`dub --build=release`

Otherwise I am getting errors descripted above

Optlink isn't able to link object files produced by ldc. Could you try an x64_86 build? You'll need the Microsoft linker.

You don't need VS, the Windows SDK should be fine too. It's a free download :)

How to check if it's installed and how to use linker from it?

If it's installed you can find it in the programs and features list as 'Windows Software Development Kit for Windows X'. The DMD installer will look for it during installation, so reinstalling DMD after installing the SDK should work. I'm not sure how LDC does it, but last time I installed LDC it also just worked.
