Building master branch fails (on a prestine environment)

[adinapoli]

Hello guys,

I have tried to build the library (as downloaded from github) doing:

pulp dep update
pulp build

The latter command fails with:

☁  purescript-echarts [master] pulp build
* Building project in /Users/adinapoli/programming/purescript/purescript-echarts
Multiple errors:

Error at bower_components/purescript-integers/src/Data/Int.purs line 31, column 1 - line 37, column 1:
Error in module Data.Int
Unknown type class 'Semiring'

Error at bower_components/purescript-integers/src/Data/Int.purs line 37, column 1 - line 41, column 1:
Error in module Data.Int
Unknown type class 'ModuloSemiring'

Error at bower_components/purescript-integers/src/Data/Int.purs line 41, column 1 - line 44, column 1:
Error in module Data.Int
Unknown type class 'Ring'

Any idea of what I'm doing wrong?
Thanks!
Alfredo

It looks like you need to update your compiler, the Semiring hierarchy was added to the prelude a little while back.

[adinapoli]

Makes sense, thanks!

[adinapoli]

Update: Sorry for being stupid, but when you say update your compiler, did you mean the psc executable alone? I did upgrade it, but it didn't make any change. I did only installed purescript in a sandbox (with cabal install purescript), moved psc into my .cabal/bin folder and that's it. Is there any other special operation I need to perform?

[garyb]

That's odd, what do you get from psc --version? The Semiring stuff was added in 0.6.8 so if it's later than that it should definitely be working.

[garyb]

Ah, you might need to copy psc-make over too, if you only did psc.

[adinapoli]

Ah! for some reason cabal was installing 0.6.7.x, I'm currently installing 0.6.9 and then I will give it a spin. Thanks for the patience!

[adinapoli]

Great, it worked! Thanks a lot!

Glad to hear it 😄
