Installer does not work in OS X El Capitan #158

Closed jpcofr closed 8 years ago

jpcofr commented 9 years ago

The installer fails for some reason. I guess that the problem is the new OS X security system but the error is not meaningful and I could not test my guess.

Thanks. Apparently, we are not allowed to write in /usr/bin anymore.

Can you try this package: https://ci.zjyto.net/job/BNFC/job/bnfc-bdist-mac/lastSuccessfulBuild/artifact/dist/BNFC-2.8-mac.pkg

Thank you so much, that helps a lot!

I would like to add that it did not work to install it though 'cabal install bnfc' either. It is System Integrity Protection(aka rootless) feature that was introduced in El Capitan that is the cause. Since it restricts access to the path where transformer package is installed. There is however a way around it:

  1. Reboot and press down command+r to enter Recovery Mode.
  2. In the menu, go to Utilities > Terminal to start the terminal.
  3. Enter: csrutil disable; reboot, this will disable System Integrity Protection and reboot.
  4. Now install it again: cabal install bnfc
  5. After it is done, reboot in Recovery Mode.
  6. Go to terminal and enter csrutil enable; reboot, to enable System Integrity Protection again.

@seanpavlov do you run cabal as root or does El Capitan prevents you from installing stuff even in your home directory??

johnjcamilleri commented 8 years ago

After upgrading to El Capitan, I ended up removing everything Haskell related on my system as follows:

rm -rf ~/.cabal
rm -rf ~/Library/Haskell
sudo /Library/Haskell/bin/uninstall-hs all --remove
brew uninstall ghc cabal-install

And then installing again through homebrew with: brew install ghc cabal-install. Maybe a bit extreme, but this gives you GHC 7.10.2 which seems to work well with SIP enabled. However now I get a compile error when trying to build BNFC 2.8:

src/LexBNF.x:166:38:
    Not in scope: ‘ord’
    Perhaps you meant one of these:
      ‘or’ (imported from Prelude), ‘odd’ (imported from Prelude),
      ‘ord#’ (imported from GHC.Exts)

Ok, I managed to build by making a few small changes, as shown in pull request #161

gdetrez commented 8 years ago

Thanks to @johnjcamilleri's fix, the latest version on hackage should fix this problem. Please re-open if id doesn't.

pascalh commented 8 years ago

It's not a big thing, but the current bnfc version in the master branch of the github repository is 2.8 whereas the uploaded cabal file at hackage (an the version in branch 2.8.x) already has version 2.8.1.

I am actually not sure whether this is a mistake or it is just me not understanding the idea of both branches. Sorry to bother you with such small issues.

gdetrez commented 8 years ago

The idea is that the new features implemented in master should be released as 2.9.0 but I wanted to release a fix for the new GHC, so I created the 2.8.x branch as a maintenance branch for 2.8.0.

Apparently cabal won't let me use "master" as a version but I can remove the version field altogether. Maybe it would be clearer to have no version in master and add one when a release is created?

pascalh commented 8 years ago

Thanks for the explanation. I think the current work flow is useful as it is. I just wanted to make sure that implementing new features in the master branch follows the projects' guidelines, since I often saw it the other way around (a development branch for new features and the master containing bug fixes for the current version).
