MacOS support

Can I build this on MacOS Catalina?

Currently when I'm trying to launch stack build I have an error

Installed GHC.

Error: While constructing the build plan, the following exceptions were encountered:

In the dependencies for Cabal-2.4.1.0:
    unix must match >=2.6.0.0 && <2.8, but the stack configuration has no specified version  (latest matching version is 2.7.2.2)
needed due to idris-cam-0.1.0.0 -> Cabal-2.4.1.0

In the dependencies for idris-cam-0.1.0.0:
    unix must match <2.8, but the stack configuration has no specified version  (latest matching version is 2.7.2.2)

Some different approaches to resolving this:

  * Recommended action: try adding the following to your extra-deps in /Users/bmwant/projects/idris-cam/stack.yaml:

- unix-2.7.2.2@sha256:e69269a17b9fa26cb77f3f55e86c39d0a4940ccfa0c4bc20826919d2572076ad,3496

Plan construction failed.

Is it related to the OS used or some specific versions of toolset is required? Any guidance of how I should debug/resolve this error would be helpful.

you have to change stack.yml, comment and uncomment some platform specific settings:
https://github.com/thautwarm/idris-cam/blob/d25827fa8cf2203fdef65d685a04c1b305fcf430/stack.yaml#L6

personally I'd suggest you use
https://github.com/thautwarm/Quick-Backend

I will keep maintaining it as a future research, the technique stuffs of this project are out of date.

So I was able to install on my Ubuntu 18.04 machine with a following configuration stack.yml

resolver: lts-13.17

and then also

$ pip install toolz
$ pip install numpy

before doing pip install idris-python
