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 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:

Answer 1

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 2 gems installed 

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
