How to fix make iOS error? #2

Closed JulianZhang closed 6 years ago

Dear

I'm following your blog try to run the app. But failed when make iOS

Can we set a lts version for this project.

./call make iOS

Hmm, I don't think it's possible to set an LTS when using cabal new-build? If there is, that would be neat :)

Alternatively, I should really have frozen the packages to specific versions, and also I forgot to remove the freer package, which is not needed at all in the Hello World example. To quickly move on, just remove this line https://github.com/Tehnix/MobileHaskellFun/blob/6842d3845d923eaf2907886c7776f25c76347a62/hs-src/MobileFun.cabal#L16.

I'll look into the package problem in the meantime (have to build it all from scratch on my work laptop...).

Tehnix commented 6 years ago

I've updated the .cabal file, added the blog post quick install instructions to the README, and also commented out the libffi install in the setup-tools.sh.

If you pull down the changes, the ./call make iOS should work now (only needed the cabal change for that one) :)

I'll close this, but we can reopen if there are other issues, of if you have any suggestions as to how we can get an LTS or something like that to work nicely with this.
