I can succesfully install the gsl library in my home directory, but when I try to install the gsl gem I get a big list of errors that I do not understand. I am wondering if someone could give me some idea why I could be getting those errors. I can say I have:
Installed gsl succesfully; at least that is what it looked like. I pointed the path to gsl-config
This is what the error log looks like:
...
Ubuntu 11.10 includes a newer version (1.15) of libgsl0 that is not compatible with ruby/gsl :
Must install older version 1.14 for ruby/gsl to work:
curl -O http://mirror.veriportal.com/gnu/gsl/gsl-1.14.tar.gz tar xvzf gsl-1.14.tar.gz cd gsl-1.14 ./configure make sudo make install sudo gem install --conservative --no-ri --no-rdoc gsl Installation works OK and test on Ubuntu and Debian Squeeze:
Fetching: narray-0.6.0.1.gem (100%) Building native extensions. This could take a while... Fetching: gsl-1.14.7.gem (100%) Building native extensions. This could take a while... Successfully installed narray-0.6.0.1 Successfully installed gsl-1.14.7 2 gems installed which OS are you on?
first you need to install gsl and gsl-devel RPMs on your OS as root... e.g. on Fedora Linux:
sudo yum install -y gsl gsl-devel then do the gem install gsl or bundle install
without the gsl-devel package, it will not find the correct C-header files.
You also need to make sure that those header files are installed in a location which is included in either the LD_LIBRARY_PATH, or listed in /etc/ld.so.conf
If you have:
gsl-config --version) (e.g. in Ubuntu 14.04),Then try https://github.com/siefca/rb-gsl -- it's tweaked for such configuration.
It should also work with Ruby 1.9 and Ruby 2.0.
If you're using bundler to manage gems in a project then put a line in your Gemfile:
gem 'gsl', :git => 'git://github.com/siefca/rb-gsl' Cheers!
For anyone still struggling to install this with the gsl_matrix_complex_equal issue.
If you have run brew install gsl which will as of this writing install 1.15 and then attempted to install the ruby bindings, you will potentially run into this problem.
Using this repo as your rb-gsl gem source solves the issue: https://github.com/30robots/rb-gsl
However, if you have a newer version of rubygems, that repo makes a call to Gem#searcher which is a deprecated and now removed method.
My repo updates that call to use the Gem::Specification API:
https://github.com/whistlerbrk/rb-gsl
So in short:
brew install gsl on OSX
and in your Gemfile:
gem 'gsl', :git => 'git://github.com/whistlerbrk/rb-gsl.git'
under ubuntu 13.04 this solves the problem:
sudo apt-get install libgsl0-dev
no need to manually install an old version
Attention it seems not working with Ruby 2.1.0.
For Ubuntu 12.04 LTS and Ruby 2.0.0:
cd ~ wget ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz tar xvzf gsl-1.15.tar.gz cd gsl-1.15 ./configure make sudo make install Check if GSL 1.15 is correctly installed
gsl-config --version Then install gem (gsl 1.15.3)
gem install gsl For ubuntu 13.10, ruby 2.0.0 works fine next-
curl -O http://ftp.unicamp.br/pub/gnu/gsl/gsl-1.16.tar.gz tar xvzf gsl-1.16.tar.gz cd gsl-1.16 ./configure make sudo make install sudo gem install --conservative --no-ri --no-rdoc gsl Attention: Ami Navon wrote-

It is not actual now for gsl-1.16/ruby-2.0.0
lsb_release -a Ubuntu 14.04.1 LTSruby --version ruby 2.1.2p95
Important: Install gsl development package (https://askubuntu.com/a/490475/121418)sudo apt-get install libgsl0-dev
Add this line in Gemfilegem 'rb-gsl'
Install gem via Terminalbundle install
Verifybundle show rb-gsl
/.rvm/gems/ruby-2.1.2/gems/rb-gsl-1.16.0.4
gsl-config --version
1.15
Use require "gsl" in ruby file if necessary
On my fresh install of Mac OS X Yosemite, I needed specifically 1.15.3, and homebrew can't get that for me (there is no brew install gsl115)
curl ftp://ftp.gnu.org/gnu/gsl/gsl-1.15.tar.gz > gsl-1.15.tar.gz tar xvzf gsl-1.15.tar.gz cd gsl-1.15 ./configure make sudo make install gem install gsl
