error building. deltaMini not defined

[diegodorado]

Where is deltaMini defined? I get this error when I do cabal install

`Preprocessing library feedforward-0.0.1... [1 of 5] Compiling TidalHint ( src/TidalHint.hs, dist/build/TidalHint.o )

src/TidalHint.hs:70:39: error: Variable not in scope: deltaMini :: String -> t `

@diegodorado That's a tidal function but isn't in the released version, you'll have to build from the github version - master should be fine.

[diegodorado]

@yaxu , You mean to install Tidal from source with cabal install after cloning the repository? if so, how do I link that Tidal to this project so it understand deltaMini?

[yaxu]

@diegodorado Yes, good question! This seems to be very difficult with the new style of cabal install, so I went back to the old one. Clone tidal and install it from that folder with cabal v1-update; cabal v1-install. Then the same install command with feedforward should work. You might need to remove the 'new-style' package file. If you run ghci it will tell you where this file is when it starts.

I get unrecognised command: v1-update

cabal-install version 1.24.0.2 compiled using version 1.24.2.0 of the Cabal library

[yaxu]

Ah, then you have an old version of haskell/cabal. No problem - cabal update; cabal install should work fine in that case

[diegodorado]

I am not getting it right... I could install tidal from source, and it istalled tidal version 1.4.6

Now trying to do the same for feedforward, I get this error

➜  feedforward git:(master) cabal install
Resolving dependencies...
In order, the following would be installed:
vector-th-unbox-0.2.1.7 (via: math-functions-0.3.3.0) (reinstall) (changes: vector-0.12.0.3 -> 0.12.0.1)
math-functions-0.3.3.0 (via: mwc-random-0.14.0.0) (reinstall) (changes: primitive-0.6.4.0 -> 0.6.2.0, vector-0.12.0.3 -> 0.12.0.1, vector-th-unbox-0.2.1.7 removed)
mwc-random-0.14.0.0 (via: tidal-1.4.5) (reinstall) (changes: math-functions-0.3.3.0 removed, primitive-0.6.4.0 -> 0.6.2.0, vector-0.12.0.3 -> 0.12.0.1)
tidal-1.4.5 (via: feedforward-0.0.1 feedforward-0.0.1) (new version)
feedforward-0.0.1 (new package)
cabal: The following packages are likely to be broken by the reinstalls:
tidal-1.4.6
Use --force-reinstalls if you want to install anyway.

[diegodorado]

If I run it with --force-reinstalls it uses tidal 1.4.5 and get the no deltaMini defined error

[yaxu]

Hm, try to pull now. I constrained feedforward to tidal 1.4.6

[yaxu]

Otherwise, sometimes the best thing is to remove all the installed libraries and start again. You can do that by removing ~/.cabal and maybe ~/.ghc

[diegodorado]

Great! it is working now! thank you for the support!, feedforward is a lot of fun!

[yaxu]

Nice one!
