Brassica SCA [v1.0.0]

I tried that and got the following error:

Code: Select all

cli-pb/Main.hs:40:13 error:
    • Variable not in scope
        asum :: [Parser ParadigmInput] -> Parser ParadigmInput
    • Perhaps you meant one of these:
        'sum' (imported from prelude), 'asumC' (imported from Conduit)
      Perhaps you want to add 'asum' to the import list in the import of
      'Data.Foldable' (cli-pb/Main.hs:8.1-29).
   |
40 |         <$> asum
   |             ^^^^

And then error messages caused by the above.
This is weird, as it seems to be an error in the compiling, which I'm sure worked fine when I tried it yesterday; I'm not sure what's going on.

This is in the paradigm builder (in directory cli-pb). Perhaps you didn’t try building it yesterday.

It’s a strange error though… basically it’s saying that it can’t find the function asum, which is weird since it’s a common function. My best guess is that you’re somehow stuck on a very old (pre-4.16) version of the base library, which didn’t define asum. What does ghc --version give you?

One thing I should recommend is downloading GHC etc. directly rather than using what comes with your distros -- distros often lag behind, especially Debian-based ones (cough cough "stable" cough cough).

It claims to be The Glorious Glasgow Haskell Compilation System, version 9.0.2

Wait… this makes me realise… I thought I recommended GHCup already. But looks like I didn’t — no wonder Lērisama is having problems with painfully old GHC versions.

Lērisama, if you’re not already using GHCup, clean out your existing Haskell installation completely and reinstall it via GHCup. It should solve your problems. Distro packages of Haskell are famously bad.

Aha, I was not aware of that. I'll try that at the weekend.

I managed to install ghcup tonight, and tried to recompile it. I got a lot of

Code: Select all

/usr/bin/ld.gold: error: cannot find -lgmp
collect2: error: ld returned 1 exit status
`gcc' failed in phase `Linker'. (Exit code: 1)

As well as warnings that ~ would soon cause an error, that memset ans memcpy is deprecated. It is also complaining that importing Data.Semigroup is redundant.

You probably need libgmp installed then.

I had just shut the pi down. Sod's law strikes again!

It works!

[Raphael]

It works!

[bradrn]

It works!

Amazing!
