Thread: How to install git-annex on 13.1/2?

  1. #1

    Post How to install git-annex on 13.1/2?

    Unfortunately git-annex isn't in the repos of openSuSE and I cannot install it from source as described under http://git-annex.branchable.com/install/fromsource/ .

    Already done:
    1) # zypper install haskell-platform [done]
    2) $ cabal update; cabal unpack git-annex [done]
    3) $ cd git-annex-5.20.. [done]

    4) What are the corresponding packages in suse for the deb-packages libgnutls, libgsasl, libxml2, zlib?

    5) $ cabal configure
    [output]
    checking UPGRADE_LOCATION... not available checking git...
    no setup: ** the git command is required

    6) $ cabal install --only-dependencies
    [output]
    cabal: Error: some packages failed to install: gnuidn-0.2.1 failed during the configure step.
    The exception was: ExitFailure 1
    network-protocol-xmpp-0.4.6 depends on gnuidn-0.2.1 which failed to install.

    ... How can I install git-annex on openSuSE 13.1/2?

    Thank's very much for the answers in advance

    OK, here is what I did which almost works, and where I think you can diverge from what I did...
    Before I describe what you should do to almost install, I should first describe what may be an unsurmountable obstacle...
    Eventually you'll run into the following error
    Code:
    # cabal install git-annex
    Resolving dependencies...
    Configuring gnuidn-0.2.1...
    cabal: The program c2hs is required but it could not be found.
    Failed to install gnuidn-0.2.1
    cabal: Error: some packages failed to install:
    git-annex-5.20150317 depends on gnuidn-0.2.1 which failed to install.
    gnuidn-0.2.1 failed during the configure step. The exception was:
    ExitFailure 1
    network-protocol-xmpp-0.4.6 depends on gnuidn-0.2.1 which failed to install.
    Unfortunately, I don't know if there is a solution for the above.
    First Issue:
    Although c2hs is installed using cabal, for some reason the github-annex install can't recognize it.
    Second Issue:
    A suitable GNU IDN package needs to be installed.

    An Internet search quickly reveals that the above package was created only for Debian and Ubuntu.
    Researching the package a bit further, it contains many things but probably the essentials we want are at the following project page
    http://www.gnu.org/software/libidn/
    The related page to download sources does not list versions which correspond with the Debian/Ubuntu package name or the required version is ancient. In any case, I downloaded the latest available, unpacked it, compiled and configured it but the Haskell install doesn't recognize the GNU IDN I installed.
    (If you're not able to do this, post and I'll describe this in detail, too)

    So, how sad that installing the pre-compiled Haskell version of github-annex won't work (as I describe below).
    You'll have to try installing it from source but my guess is that you'll likely run into the same problem.

    ****************************************

    After that sad news... Here are the steps to set your system up with Haskell and likely all the dependencies that can be fulfilled...

    Prepare your system
    the following is for a 13.1 system, but at least for 12.3 and 13.2 you can probably just change the version number in the following commands to adjust for your system

    Add the following repos with the following zypper commands

    Python Development
    Code:
    zypper ar http://download.opensuse.org/repositories/devel:/languages:/python/openSUSE_13.1/ openSUSE-13.1-Python-dev
    Packman Essentials (Note: This is not the Multimedia repo)
    Code:
    zypper ar -f -n packman-essentials http://packman.inode.at/suse/openSUSE_13.1/Essentials/ packman-essentials
    Note: You'll find that a necessary vendor change will be offered for liblzma5, select it (likely option 1)

    You may be able to shortcut installing dependencies because I found github-annex has been pre-packaged in the Hakell System
    At this point you may be able to simply run the following commands
    Install cabal install
    Code:
    zypper in cabal-install
    Run update. When you do this, it will find that the Haskell repo (not the openSUSE and Packman repos openSUSE has) has a more modern version so the following will both install the latest version and initiate a Haskell update automatically
    Code:
    cabal install cabal-install
    When the update has completed, I did a search for and surprisingly found a pre-compiled github annex with "cabal list gitnub-annex" so I installed with
    Code:
    cabal install github-annex

    Now, if you run into any issues you can follow what I <actually> did after adding the repos above

    Install the following packages as suggested by the instructions to install on Fedora
    http://git-annex.branchable.com/install/Fedora/
    NOTE: In the following command I installed "libidn-devel" instead of "libldn-devel" which I believe may be a typo in the original Fedora instructions
    I also added git based on your original post
    Code:
    zypper install libxml2-devel gnutls-devel libgsasl-devel ghc cabal-install happy alex libidn-devel git
    Update the system running cabal
    Code:
    cabal update
    Updated cabal-install as recommended with the following command which appears to also automatically update
    Code:
    cabal install cabal-install
    Install c2hs. Although it is a dependency, the docs say it's well known that installing github-annex won't automatically list c2hs as a required dependency so the following installs manually
    Code:
    cabal install c2hs
    Then I installed github-annex which will end with more or less the error described at the top of this post
    Code:
    cabal install github-annex
    Note the diff between what I actually did compared to the suggested shortcut...
    I actually installed all the dependencies recommended for a Fedora install whereas I'm guessing that you may not need to install the dependencies manually if installing github-annex using cabal is able to automatically install all dependencies. The two added repositories provided the packages needed for the dependencies.

    It might also be that despite the error I ran into, the app (github-annex) might actually work... It may be that the install fails because of its own bugs and shortcomings and all that's necessary is to create the config file manually (since creating by install failed)... And then the app might work because both c2hs and GNU IDN exist.

    HTH and Good Luck,
    TSU

    FYI -
    Considering the problems installing github-annex properly,
    You might consider one of their alternative implementations...

    I didn't try running it, but you can download one of the following tarballs, extract and "just run"
    https://downloads.kitenet.net/git-annex/linux/current/

    According to the included README file, it's expected but not guaranteed to work.

    Dear TSU,

    thank you very much for your relplies. Yes it worked more or less.
    Using the webapp the files are not well transfered and are not well synced, only linked files appear.

    Running the cabal install I run into the same error. I'll give it an other try ...

    PS.: It would be great to see git-annex in the repos, as it is useful for suse servers.

    I also agree it looks like a possibly useful app (else I wouldn't have spent so much time on it).
    It looks to me like the problem is mainly in the install script, for now I can't see how their install script will work on anything but Debian/Ubuntu. My guess the remaining obstacles if fixed would make the script cross-distro would be relatively easy to fix if done by the project developers so maybe submitting a request through their forums/mail list or whatever might encourage them to do the work, particularly if you point them to what was posted in this thread.

    You might also suggest to them using OBS to easy create packages for all distros with minimal effort.
    Else, they can continue to support multiple pages dedicated to each distro the way they're doing now.

    Yes I run once again in the same failure.

    ends up with the following
    Code:
    cabal: There is no package named 'github-annex'.
    You may need to run 'cabal update' to get the latest list of available
    packages.
    and cabal update doesn't help.

    I run the above steps on a 13.2 system and chaged the version numbers respectivelly.

    I'll also try on a 13.1 system.

    best regards
