Installing clisp on OS X Leopard / PowerPC

Note: these scripts assume you already have Xcode installed, see https://macintoshgarden.org/apps/apple-xcode and install Xcode 3.1.4.

It appears 2.39 was the last version of clisp which shipped a binary release for OS X / PowerPC:

• https://sourceforge.net/projects/clisp/files/clisp/2.39/clisp-2.39-powerpc-apple-darwin8.7.0-8.7.0.tar.gz/download

It doesn't work out of the box

A bit of fiddling revealed that this binary release appears to:

• rely on being placed in /usr/local/lib/clisp
• rely on the presence of /sw/lib/libreadline.4.dylib
• have been built against readline 4.3 (4.2 will fail with dyld: Symbol not found: _rl_insert_mode)

$ cd clisp-2.39
$ ./clisp
./clisp: /usr/local/lib/clisp/base/lisp.run: No such file or directory

$ sudo mv clisp-2.39 /usr/local/lib/clisp
$ cd /usr/local/lib/clisp
$ ./clisp
dyld: Library not loaded: /sw/lib/libreadline.4.dylib

$ otool -l clisp | grep ' name'
         name /usr/lib/dyld (offset 12)
         name /usr/lib/libSystem.B.dylib (offset 24)

Note: /sw/ appears to be the Fink installation root.

Building readline 4.3

I was unable to find any downloadable libreadline.4.dylib files, so I ended up writing a script which builds it from source.

readline 4.3 will build, but needs a small patch to its shlib/Makefile to:

• link against ncurses
• fix the version provided by the dylib (4.3, not 4)

Download or copy readline-4.3.tar.gz into ~/Downloads/, then run the attached script install-readline-4.3-leopard-powerpc.sh.

Installing clisp

Download or copy clisp-2.39-powerpc-apple-darwin8.7.0-8.7.0.tar.gz into ~/Downloads/, then run the attached script install-clisp-2.39-leopard-powerpc.sh.

clisp should now run:

$ /usr/local/lib/clisp/clisp
  i i i i i i i       ooooo    o        ooooooo   ooooo   ooooo
  I I I I I I I      8     8   8           8     8     o  8    8
  I  \ `+' /  I      8         8           8     8        8    8
   \  `-+-'  /       8         8           8      ooooo   8oooo
    `-__|__-'        8         8           8           8  8
        |            8     o   8           8     o     8  8
  ------+------       ooooo    8oooooo  ooo8ooo   ooooo   8
