2.2.1 Debian GNU/Linux

The following approach should work if you are on Debian/Sarge and your /etc/apt/sources.list file is set up in such a way that it finds also nonfree and contrib packages:

     # Necessary:
     apt-get install wget gnuplot dx
     apt-get install cmucl cl-infix cl-asdf
     
     # Recommended:
     apt-get install libsuperlu3 libsuperlu3-dev
     apt-get install libumfpack4 libumfpack4-dev
     apt-get install slime
     
     # Documentation (recommended)
     apt-get install cmucl-doc cmucl-source hyperspec
     
     # get Femlisp by CVS or FTP, it is extracted into a directory 'femlisp'
     #cvs -z3 -d:ext:anoncvs@savannah.nongnu.org:/cvsroot/femlisp co femlisp
     wget -O - http://www.femlisp.org/femlisp-current.tar.gz | tar xzvf -
     
     cd femlisp          # change to the Femlisp directory
     
     # if you have installed SuperLU and/or UMFPACK above:
     make superlu        # compiles the SuperLU interface
     make umfpack        # compiles the UMFPACK interface
     
     # if you want automatic 2D triangulation:
     make triangle       # gets and compiles the Triangle mesh generator
     
     # compile Femlisp
     make configure      # interactive setup (choose cmucl)
     make femlisp        # compiles Femlisp and creates an executable
     
     # we are done
     make documentation  # generate the Femlisp documentation

Now you can continue as described in Emacs configuration.
