Linker errors

Hi - vibe newbie here. Can someone shine some light on what's going wrong here and how to fix it.

Using current DMD, current DUB on Win 10.

Thanks for any help!

It's using the LLD linker, which was added recently as an experimental
alternative to the Microsoft linker. I haven't tried it yet, so I'm not
sure how well it works, but you could try to build with -a x86_mscoff
to see if 32-bit builts work properly.

Alternatively, you'd have to go the classic path and install the C++
tools of VisualStudio (community edition). DMD should then automatically
pick up the Microsoft linker. LDC2 also works as an alternative on Windows.

Thanks for your help - much appreciated. It worked fine - alas ... there are quite a number of warnings

Do they hail from compiler upgrades that are not yet handled in the vibe sources? Or are there any other legitimate reasons for these peskies? If compiler 'incompatibility', when can we expect a version that is in synch with the compiler progress?

Finally, a thing that puzzles me: I build my little server, run it successfully, then Ctrl-C it and get my Windows command prompt back. When I then try to delete the exe I just built, I get 'Access denied'. I have to end the command prompt that spawned the exe in order to being able to delete the exe - what's going on??

Thanks for again for anyone who can shed light on either or both of my questions.

Cheers,
Kai

I just tagged vibe-core 1.4.4 yesterday with all warnings on the latest DMD fixed. A dub upgrade should get rid of these.

I still have to fix the toHexString one, didn't notice it up to now. The linker warnings can safely be ignored, though. They are a rather silly limitation caused by the way how object files are generated by the compiler, but unless anything crashes within eventcore this will not have any visible side effect.

Windows detaches the terminal from the process when pressing Ctrl+C once (press twice to kill the process). It seems like the Ctrl+C handler in vibe-core did not manage to properly shut down the process. That could actually be fixed by vibe-core 1.4.4 if any worker threads/tasks are used by the server. If not, does that also happen with the examples/http-server project in vibe-d for you? I'd try to reproduce that locally then.

Thanks for again for anyone who can shed light on either or both of my questions.

Yes, it happens there as well.

I opened a PR to fix this, which will be in the next vibe-core version:
https://github.com/vibe-d/vibe-core/pull/99

When running the example now, it exits properly, except for a warning
that socket descriptors have been leaked. This is because the example
does not call stopListening on the HTTPListener returned by
listenHTTP, and the warning messages have just been introduced. I'll
post a fix for that, too.
