So you'll probably have to use the MS compiler or clang to emit an MSVC-compatible object file, and then use either -m32mscoff or -m64 for DMD.

What am I missing? I have never used dpp, but the github page says you should use LDC, not DMD. And I could not find anything implying gcc is supported. what the docs says is about to use ldc2 to build from source code, which I did. That failed dmd call is done by d++ internally.

Re: Reflection on the book D web development.
It's not my related to a lack of knowledge of the d-language but the complexity of the vibe.d framework itself. What I understand are : 1: jade/diet .dt templates, inheritance,includes,markdown. 2: A simple form with POST method. Then it stops. What I find too complex: - Sessions, session data , session variables - Handler functions and delegates, compile-time reflection, prefixes, annotation. - Authentication - Validating user input This can be improved by improving documentation in very small steps. As comparison here a tutorial of ruby-flask which uses only small steps so everything can easily and completely be understood. Something like that for vibe.d would be very interesting. https://www.youtube.com/watch?v=3mwFC4SHY-Y

Compare, I own a book on flask development, and I understand 100% of it. Which means I can use dlang for anything except QT and serious web development ... How would you like this to be improved? I'm personally interested in making vibe.d more accessible.
Re: lambdas with types

Doing something like below fails because I don't seem to be
able to make a templated lambda that just takes types. Is the
only way to do something similar to create a separate function
to handle the condition, or is there some other way to do
something with similar flexibility?
import std.stdio: writeln;
import std.meta: allSatisfy;
void foo(Args...)(Args args)
if (allSatisfy!(x => is(x == double), Args))
{
writeln("works");
}
void main() {
foo(1.0, 2.0);
}
with type functions this syntax should work.
