How to Install Berkshelf version3 on Cygwin 64bit

Installation of Berkshelf v3 on Cygwin is known to be very diffcult, but I have finally found the way. 😄

You can successfully install it by following the procedure below.

(As at 2014/6/8, v3.1.3 is available)

Why is it so difficult ?

Among the gems on which Berkshelf depends, there are two gems that are difficult to install:

ffi
dep-selector-libgecode

In other words, if you can install just these two gems, you should be able to install Berkshelf.

So Let’s give it a try!

Target Environment

Cygwin 64bit

(I used Windows 7, but believe it will also work on Windows 8)

Prerequisites

Install the following:

apt-cyg
rbenv , ruby version 2.1

install apt-cyg

Put this file in a directory of your $PATH

https://raw.githubusercontent.com/kou1okada/apt-cyg/master/apt-cyg

e.g. C:\cygwin64\usr\local\bin\apt-cyg.

and set it executable

chmod 0755 /usr/local/bin/apt-cyg

install rbenv, ruby 2.1

Install required packages using apt-cyg

$ apt-cyg install git gcc-core  gcc-g++ make zlib-devel curl \
autoconf  libiconv libiconv-devel rsync patch unzip openssh openssl-\
devel libxml2-devel libxslt-devel  libffi-devel libgdbm-devel

Install rbenv and ruby-build

This follows the official manual.

git clone git://github.com/sstephenson/rbenv.git ~/.rbenv
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc

$SHELL --login

rbenv install 2.1.0-rc1
rbenv global 2.1.0-rc1
rbenv rehash

That’s it!

Validation/confirmation

$ ruby -v
ruby 2.1.0dev (2013-12-20 trunk 44301) [x86_64-cygwin]

Installing ffi

ffi/ffi#284 (comment)

You can install ffi per the above comment from RSmirnov:

$ apt-cyg install libffi6 libffi-devel pkg-config
$ export PKG_CONFIG_PATH="/lib/pkgconfig"
$ gem install ffi

Installing dep-selector-libgecode

# Create symlinks to gcc48.exe, g++48.exe
$ ln -s gcc.exe /usr/bin/gcc48.exe
$ ln -s g++.exe /usr/bin/g++48.exe

# Download and unzip gecode 3.7.3
$ wget "http://pkgs.fedoraproject.org/repo/pkgs/gecode/gecode-3.7.3.tar.gz/7a5cb9945e0bb48f222992f2106130ac/gecode-3.7.3.tar.gz"
$ tar xvfz gecode-3.7.3.tar.gz
$ cd gecode-3.7.3

# Compile
$ ./configure CC="gcc48"  --disable-doc-dot --disable-doc-search --disable-doc-tagfile --disable-doc-chm --disable-doc-docset --disable-qt --disable-examples --disable-flatzinc
$ make
$ make install
# Manually install the libraries
$ cp libgecode* /lib/
$ cp -r gecode/* /usr/include/

Finally, install Berkshelf !

$ USE_SYSTEM_GECODE=1 gem install berkshelf

$ berks --version

Did it work？
