Installation problem about grex HOT 3 CLOSED

This is weird.. The ndarray crate obviously has some kind of problem, perhaps it contains a bug. This is most likely not a bug in grex itself.

Please create an issue in ndarray's issue tracker and post the entire stacktrace there. I think the people over there can help you better than I can. I develop on macOS, so I don't have a Linux machine to test on.

Another alternative:
Do you get the same error when you use the Linux binary from my repository? If not, then there is probably just an issue within the build process of ndarray.

from grex.

Thanks for the tips. The Linux binary works fine. Since grex 1.11.0 also builds fine, I have 2 versions to bisect.
Following the track that its ndarray not grex's fault, I backed up to ndarray version 0.13.0 (used by grex 1.1.0) and that builds successfully in an empty project. However ndarray version 0.13.0

when applied to grex 1.2.0 produce the attached stack trace. Hopefully by limiting the differences to between grex 1.1.0&1.2.0, ndarray 0.13.0&0.15.0, and MacOs&Linux, the stack trace that has shrunk to only 25 errors will be more suggestive. I assume we have a version mismatch problem, but since I know absolutely nothing about ndarray nor grex internals, I'm hoping for another clue to narrow my search / learning curve.

I fixed my problem with:
$ rustup update
I don't think its worth hunting down what combination of changes in the rust toolchain, ndarray, and grex caused my problem. Unless the problem reappears elsewhere.
