Install procedure doesn't work.

[drysdam]

Debian 7 64-bit here. Followed instructions in FAQ (sudo apt-get install ghc cabal-install; cabal update && cabal install implicit) and got:

extopenscad.hs:26:149: Module Options.Applicative' does not exportreader'

extopenscad.hs:26:169: Module Options.Applicative' does not export(&)' cabal: Error: some packages failed to install: implicit-0.0.3 failed during the building phase. The exception was: ExitFailure 1

Using the development version, I get up through "cabal configure && cabal install" and then hit:

extopenscad.hs:26:155: Module Options.Applicative' does not exportreader' cabal: Error: some packages failed to install: implicit-0.0.3 failed during the building phase. The exception was: ExitFailure 1

The latest version of optparse-applicative has changed it's API by removing deprecated methods. Hence its move from version 0.9.x to 0.10; you'll need to restrict the build of implicit to use < 0.10 ie. edit implicit.cabal and add the restriction below prior to building.

   optparse-applicative < 0.10,

Alternatively, edit the haskell source (extopenscad.hs) to change the deprecated references. There are hints on what to do in the github site for optparse.

Could we please get an update of this package on Hackage that fixes this build error? We've run into the same issue on NixOS: http://hydra.cryp.to/build/190835/nixlog/1/raw

I am getting this same error on ubuntu 14.04 running the installation instructions... I am searching for implicit.cabal now, but it is not apparent where it is located.

Edit: I found the implicit.cabal in a compressed file (implicit-0.0.3.tar.gz), the full path for me was:

/home/myUser/.cabal/packages/hackage.haskell.org/implicit/0.0.3/implicit-0.0.3.tar.gz

Edit again: Editing the implicit.cabal in the tar.gz didn't fix it, when running cabal install implicit I'm getting:

Ok I ended up finding the commit log for the actual change to the implicit.cabal file, the line needs to be changed to: optparse-applicative >= 0.9.0.0 && < 0.10.0,

Then on the command-line I used: cabal install optparse-applicative-0.9.1.1

then again I ran cabal install implicit.

Actually, before I discovered the command to force the package version, I wrote this Python script to remove the previously-installed version of optparse-applicative. It might not work for you, and it might break your haskell setup, but I didn't have haskell installed before I tried to install implicitCAD, so I figured I could just apt-get remove the whole haskell and cabal packages if I messed things up to bad. I didn't have to go there though!

s1,e1 = p1.communicate()

optparse_index = s1.index('optparse-applicative')
s1 = s1[optparse_index:]
optparse_end_index = s1.index('\n')
optparse_pkg = s1[:optparse_end_index]

remove_optparse = subprocess.Popen('ghc-pkg unregister --force %s' % optparse_p$
                 shell=True,
                 stdout=subprocess.PIPE,
                 stderr=subprocess.PIPE)
print remove_optparse.communicate()
p2=subprocess.Popen(['ghc-pkg', 'check'],
                     stdout=subprocess.PIPE,
                     stderr=subprocess.PIPE)
s2,e2 = p2.communicate()

i = e2.index('\n', e2.index('The following packages are broken'))
i = e2.index('\n', i+1)
#i = e.index('\n', i+1)
pkgs = e2[i:-1]
#print pkgs

These should be fixed now. Could someone verify that this issue has been resolved? I have no problems building the project now. I will close this issue eventually if I don't hear back.

I have merged a pull request addressing GHC-7.6.3 backward compatibility. Can you please try again?

[firegurafiku]

@mmachenry

Yeah, now it builds. I cannot test it at the moment, but it runs:

$ dist/build/extopenscad/extopenscad
Usage: extopenscad [-o|--output FILE] [-f|--format FORMAT] [-r|--resolution RES]

Great, thanks for your help. I'm going to close this issue. Feel free to file any more in the future or reopen this if you have another problem.
