I am trying to install ‘rasclass’ package on R (version 3.2.3) but somehow the installation always fails. The output is too large to be pasted here, but I found something interested in this question, that might be the key to solve this issue. Shortly: from the terminal I can see I have gcc-4.8 and 4.9, g++-4.8 and 4.9, and gfortran-4.8.
