Install MAFFT on Ubuntu 16 non standard folder

Question

[marongiu.luigi]

Hello,

I am trying to install MAFFT on my Ubuntu Xenia machine. I downloaded the tar archive 'mafft-7.222-with-extensions-src.tgz', extracted and called the folder 'mafft'. I moved the folder to '/usr/local/lib/' and tried to follow the instructions for the installation on non standard location. I opened the 'makefile' and it shows:

PREFIX = /usr/local
LIBDIR = $(PREFIX)/libexec/mafft
BINDIR = $(PREFIX)/bin
MANDIR = $(PREFIX)/share/man/man1
DESTDIR =

How exactly shall I modify PREFIX and BINDIR? Shall it simply be: PREFIX = /usr/local/lib/? or should be PREFIX = /usr/local/lib/mafft/? And BINDIR?

Many thanks

Note that if version 7.271 is good enough for you, you can install it via the packaging system with the command sudo apt install mafft. This will spare you the effort of a local installation.

I wanted to try version 7.222 because I had problems of memory availability with muscle; maybe mafft is better especially is ver. 7.222 is less RAM demanding...
