Hello! I'm working on a project and I was going to use LLVM
with the LLVM-D wrapper which has it's own Dub package and
everything https://github.com/Calrama/llvm-d
I've installed the package with Dub, added it to my
packages/builds dependencies.
When I build however I get an error:

I want to know if anyone here has any experience witht his by
any chance? The source of the problem? Is it a bug? Thanks for
any suggestions.
I don't have any experience with using dub's dependency
settings for projects, but regarding llvm-d itself:
1) The D API itself is not ready for active use (that's what
the C binding are currently in place for), but it does compile
and link properly in my tests, which include:
- Building with the provided VisualStudio solution file into
a static libary on Windows.
- Changing (locally) the "sourceLibrary" setting to
"staticLibrary" in package.json and running "dub build", which
provides a working static library for me with the current
master.
For some reason, however, building ("dub build") with
"sourceLibrary" leads to an assertion error I could not track
down, as I was not able to make more sense out of the output
produced by "dub build --vverbose" than that an exception had
occured.
2) I can build and run all of llvm-d's samples the following
way:
1. Clone the repo
2. cd into the local clone
3. Run the samples with rdmd, e.g. "rdmd samples/fibonacci.d".
Could you give me a minimal example I can use to reproduce the
error you've encountered? Also, you can always open an issue at
llvm-d's github repo, that's the easiest way to report problems
about llvm-d (other than mailing me).

I tried to figure out what the issue was, but it was over my
head...
What exactly has been broken for you? As stated above, I can
run all the examples fine, but if that is not the case for
someone else, I need to know about it in order to try and fix
it.

I think in this case reporting to `llvm-d` author makes more
sense.
AFAIK "calrama" is common nickname for Moritz Maxeiner, I will
send him an e-mail linking this thread.
Thanks for mailing me, I would not have seen this thread here
otherwise (I usually look at the first pages of "digitalmars.D"
and "digitalmars.D.announce" every couple of days).
I just put the package in the dependencies and import it in my
code then it does that, haven't even used any functions yet.
(When building of course)
