clisp-2.31 under Mac OSX 2.6

MEMO: clisp-2.31 under Mac OSX 2.6 for dummies

First remove any workarounds for dynamic loading.  I had to remove a 
fake dlfcn.h header file from /usr/include.  That was a hack I used to 
build earlier versions of clisp.  Another patch from OSXGNU does the 
same thing.  Try disabling that if you have it and cannot "make" clisp.

What follows was done with the tcsh shell, the default for OSX.

Download the .gz form of the package and expand with
   tar -zxvf clisp-2.31.tar.gz

Go into the clisp-2.31 folder ...
   cd clisp-2.31

Configure with by typing
   ./configure
Ignore the error near the end of the type-out.  There is no "avcall" 
feature under Mac OSX, so the message is irrelevant.

Go into the source folder ...
   cd src

Build the "Make" and configuration files (two commands) ...
   ./makemake > Makefile
   make config.lisp

First hack: increase the stack size to 16384.  Unlike previous versions 
of clisp, 8192 is just not enough.  So type
   limit stacksize 16384

Second hack: Edit Makefile, which is inside /src. I just double-clicked 
it and it opened with TextEdit.  Go down one screen, or about 35 lines 
and edit CFLAGS.  Without inserting a carriage return, add the clause 
-traditional-cpp.  The new line should look line this, ... and it's 
only one actual line!

CFLAGS =  -W -Wswitch -Wcomment -Wpointer-arith -Wimplicit 
-Wreturn-type  -fomit-frame-pointer -Wno-sign-compare -O2 
-traditional-cpp -DUNICODE -DNO_GETTEXT -DNO_SIGSEGV

Edit the file config.lisp as you like, naming your site, installation, 
etc.

Compile and build clisp by simply typing
   make

After about 20 minutes, assuming things work, test your build ...
   make check
   make test
   make testsuite

Make yourself super-user, complete the installation, and immediately 
exit as superuser ...
   su
password:yourpass
   make install
   exit

You have built clisp, but there are problems. You must set the stack 
size every time you invoke clisp, or you get "segmentation faults" and 
clisp crashes.  (It took me the longest time to see this.)  My solution 
is an alias:

   alias clisp 'limit stacksize 16384; /usr/local/bin/clisp -C'

Put this in whatever shell configuration file you use.  If you don't 
have one, create a file called aliases.mine with the above as a single 
line.  Add other aliases if you like.  Put the file in this location:

Library/init/tcsh/aliases.mine

If you don't have these folders, create ones with those names.  You can 
do it in the regular Mac environment.  Observe: I used the full 
pathname for clisp in order not to have a "circular alias reference."  
Also, I used the -C flag which makes everything compile instead of 
being interpreted.  On a machine fast enough for OSX, compilation time 
is negligible.

See you in the movies ...
