https://github.com/vibe-d/vibe.d/issues/1908 -- building default 
vibe.d example applications on win32 fails due to obscure optlink 
error. It has been like this for nearly 2 years.

I am not asking for help with this issue.

Win32 with optlink is the default build for dub on Windows, and 
given that vibe.d is the most popular D project, this could very 
well be among the first things that a D newcomer tries. If I were 
new to D, I'd likely just give up there and assume the language 
and tooling are immature.

The thread over there says that lld is shipped now with DMD. Is 
there any reason not to move to that and move away from optlink? 
It seems unnecessary to maintain and debug a separate linker when 
another more mature linker is available, working, and already 
bundled. Are there any reasons to stick with optlink as the 
default?

Yes +1 for -m64 by default. This gives a working, out of the box 
package when people download the 7z, just like in the past.

With the latest DUB, it defaults to mscoff now:
https://dlang.org/changelog/2.086.0.html#dmd-mscoff-default

DMD itself still uses OPTLINK I believe.

no when you pass -m64 to DMD then it uses LLD (shipped with the 
default distrib) and the static libraries from MinGW (shipped 
with the default distrib as well). So the idea would be that -m64 
should be the default. In this case people who don't have the MS 
toolchain setup would see their stuff compiled seamlessly and the 
others too. Even LDC supports -m64 without MS stuff nowadays.

I am about to cry now :)
Thanks for all the effort ... all the people who worked on it.

Now, I just have to see how can I port my Java code to D.

One thing you should keep in mind when you want to distribute 
your applications.
Applications compiled with lld will have a dependency to a ms c 
runtime dll.
Your application will not work on systems without this dll.
On the other hand applications compiled with ms linker from e.g. 
MS Build Tools won't have this dependency.

This is nothing bad, just a detail you have to keep in mind whole 
setting up your production build pipeline.

Kind regards
Andre
