Problems installing gsl gem

Question

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

Answer 1

This also works on ubuntu 16.04 LTS and ruby 2.2.2
sudo apt-get install libgsl0-dev

Answer 2

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

Answer 3

If you have:

• GSL 1.16 (check with gsl-config --version) (e.g. in Ubuntu 14.04),
• Ruby 2.1

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!

Answer 4

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

Answer 5

under ubuntu 13.04 this solves the problem:

sudo apt-get install libgsl0-dev

no need to manually install an old version

Answer 6

Install ruby GSL:

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
