Question

I try to install gsl gem for Ruby but it doesn’t work. i have a matrix_complex.o error.
So is there a solution to install gsl for netbeans ?
or is there a fonction quantile in an other library?
Any help would be appreciated.

Answer 1

Getting some clues from https://github.com/romanbsd/rb-gsl/issues/2 I did the following on Ubuntu:

Uninstalled my existing gsl:

sudo apt-get remove gsl-bin libgsl0-dev libgsl0ldbl

Built a new gsl

wget ftp.gnu.org/gnu/gsl/gsl-1.14.tar.gz
tar xf gsl-1.14.tar.gz
cd gsl-1.14
./configure
make
sudo make install

Installed the gem

gem install gsl

This worked for me.
