I had GSL 2.3 installed on my pc for along time now. I tried to update to 2.6 following this but when I check the version using gsl-config --version, it says that I have 2.3. Is there a step that I missed?
I missed to use gsl-config --prefix to find the path and use that in the ./configure step, instead of setting --prefix to what the post suggests.
./configure --prefix=/home/yourname/gsl
did you choose the same location as for the previous installation, or a different one? is the new location before any old location in yourPATH
