Re: Wrap C++ procedure / Parameter type float / shared library

Actually "importc" is working well. I just missed to tell Nim the direction to the shared library. So adding `{.link: "cpp/calc.so".}` and using either `importc: "calculation"` or `importcpp: "calculation(@)"` seems to be the solution.

Awesome, thanks! I'll take precaution with unstable features, but otherwise that's encouraging

Re: How does seq handle negative array index?

Hi, mratsim! I'm actually using Nim version "whatever was available when I installed it", which is "0.17.2". Thanks a lot; that sure will save me masses of time!

Re: Wrap C++ procedure / Parameter type float / shared library

Unfortunately there is also an error when using "importc". So I will check how to implement the interface between Nim and C++ with class instance as first parameter. ...the shared library will be modified related to Nims needs Thanks so far!!

Re: How does seq handle negative array index?

You need to implement `[]` that accepts `int or Backwardsindex` like I do [here](https://github.com/mratsim/Arraymancer/blob/694a83682000f644c04fad970d02bcae5161d785/src/tensor/backend/metadataArray.nim#L72-L117). (This is assuming you are on Nim `master`)

Hiring Nim Devs for Ethereum Implementation

Hey guys, we're looking to implement and maintain an Ethereum Blockchain client written in Nim, The goal of this implementation is to close the gap between research and production, by porting and tracking [py-evm](https://github.com/ethereum/py-evm), while at the same time focusing on a

Re: Wrap C++ procedure / Parameter type float / shared library

Try `importc`, `importcpp` assumes the first parameter is a class instance.

Re: experimenting with pointers and slices

That is correct, yes.

Re: [Presentation-Python-Nim] A new option for optimizing inner loops Z. D. Smith

It suggests the new direction the Nim is to be heading to (according to Araq's blog post), i.e. turning away from GC, it would more or less ruin things for the guy talking.
