Hello,

Can anyone help me? Maybe someone has seen this before. I'm getting a (strange) error when testing on OSX with dmd 2.066, the build works with the same compiler/library versions on linux x64 and windows x86 but for some reason it's not working here.

The repos are:

https://github.com/etcimon/event.d
https://github.com/etcimon/vibe.d

Both repos must be cloned in the same directory, and I use `dub run` in `vibe.d/examples/http_server`

Thanks in advance

Here's the error:

I have to specify that AsyncSignal is defined as a "final shared class", and the array is defined as a Array!AsyncSignal

I'm not sure if the compiler on OSX could act different and add the shared symbols there?

Meh, I answered my own question. Substituting it from Array!AsyncSignal to Array!(void*) and casting away worked. Looks like dmd-osx has templating problems with shared declarations.

I really had to Think Different on that one.
