Hey guys,

I've been trying to install RNAfold, however without any success. I've tried to follow the instructions t

ar xvvzf ViennaRNA-1.8.4.tar.gz
cd to the Vienna dir
 type   ./configure --prefix=your_path_to_Vienna/install_dir
 make
 make install

However the last two steps were not successful. While typing make, I got this

Any idea what can be wrong? What can I change?
