===========================================================


Here is how to make a new clisp package for SAGE:

1. Download clisp from
   http://ftp.gnu.org/pub/gnu/clisp/release/

2. Put SAGE.txt spkg-dist spkg-install and sage from the old
   clisp spkg into the new extracted directory.

3. modify src/makemake.in to build with "-O0" everywhere

4. None of the other patches in the patches directory are used - those are there for historical reasons

==============================================================
SOME NOTES:

* Made some changes to src/makemake.in so it would build on
  IA-64 linux without crashing.

0. The clisp path is hardcoded into the binary. Strangely, this *does*
not affect maxima, though it means maxima won't build unless clisp was
built in place. So one can't upgrade maxima without rebuilding clisp.
Hence whenever the maxima package is upgraded make sure to always upgrade
clisp.

Also there is an OPTIon to run clisp that avoids this hardcoding issue,
which we use.

1. I replaced some documentation files by empty ones to save space:

cd doc
echo "" > impnotes.html
echo "" > mop-spec.pdf
echo "" > mop.xml
echo "" > impbody.xml
echo "" > impext.xml
echo "" > clhs-ent.xml
echo "" > impbyte.xml
echo "" > impent.xml

 Go to
         http://clisp.cons.org/

 for complete documentation.

Same remarks for src/ChangeLog:

 cd src
 echo "">ChangeLog

2. I removed the ffcall directory which is quite large and only needed
for the foreign function interface, which we don't need for SAGE/Maxima.

3. I removed the tests directory.

-----------------------

4. In order to build Clisp on Cygwin, I had to do the following:
    1. add --ignore-absence-of-libsigsegv to the ./configure options of spkg-install for clisp
    2. go into src/unix.d and make the following modification near the end of the file: (this was only for version 2.40 -- not needed for 2.41)
    /* Interpretation of FILETIME structure: */
    #ifdef UNIX_CYGWIN32
      #define WIN32_LEAN_AND_MEAN
      #include <windows.h>
      extern long time_t_from_filetime (const FILETIME * ptr);
      extern void time_t_to_filetime (time_t time_in, FILETIME * out);
 
      /* FIX BY GEZ */
      #if defined(UNIX_CYGWIN32)
        #ifdef WIN32
          #undef WIN32
        #endif
      #endif
      /* /FIX BY GEZ */
    #endif
 
windows.h defines WIN32 and that causes several items to be used in both UNIX and WIN32 forms later on.

-----------------

NOTE. I had included libsigsegv, but couldn't get it to build on OS X
      (the included config file seems way out of date...).

==================================================

Here's a Solaris-related note from Wilson Cheung:

Note that the only reason lisp is needed for SAGE is in order
to build maxima.

Alright, I tinkered some more with sage 0.10.3 today...commented out
the clisp section in spkg/install and maxima actually did find the
already-installed system installation of gcl 2.5.3 but said it needed
to be rebuilt with "--enable-ansi".

So I upgraded the system installation of gcl to the newer gcl 2.6.7
version and added the "--enable-ansi" flag and now sage builds
maxima OK.
