scsh-0.6/CVS_README

		Welcome to the Scsh CVS Repository !!!



This file contains some instructions about how to build Scsh after you
freshly checked out the "scsh-0.6" module. These instructions do *not*
apply to the module named "scsh" or the Scsh distribution itself.

There is currently no scheme to tag working snapshots of the
repository, so anything may happen during the build process. The scsh
team does in general *not* provide support for code obtained from the
CVS repository.

During the build process a number of auto-generated files not included
in the CVS repository are built. It is highly recommended to follow
these instructions carefully as otherwise incompatible versions of
generated files may result. Note that you need GNU make for this
process.

To build Scsh, proceed as follows:

1.) You must have a working version of Scheme 48, version 0.53. Nothing
    older, nothing newer. Just 0.53. If you don't have, get it from
    http://www.s48.org/0.53/scheme48-0.53.tgz and install Scheme
    48. Change the value of the variable BUILD_RUNNABLE in Makefile.in
    so that it will point to the Scheme 48 executable.

2.) "cd" into the directory which contains the source code (normally
    scsh-0.6) and run the script autogen.sh:

    ./autogen.sh

    This will take several minutes and generate the source code for
    the virtual machine and two images the Makefile relies
    on. Furthermore the configure file will be generated. This script
    calls autoheader and autoconf from the GNU Autoconf package. You
    will need a recent version of Autoconf. Version 2.52 is okay,
    version 2.13 is too old.

3.) Configure the system:

    ./configure

    You presumably want to add the --prefix flag here to determine the
    installation directory. This will generate the Makefile.

4.) Build the system:

    make

    If anything fails here, fix the problem and/or contact the authors.

5.) You should have a runnable version of the system that can be
    started in the main directory like this:

    ./go

6.) To install Scsh, type:

    make install

    Note that it is not recommended to have a CVS version of Scsh for
    daily use.

7.) If you intend to build on a different platform later, do a 

    make distclean

    and restart at step 3.


You should repeat the whole build process whenever there are changes
to files in the directories scheme/vm, scheme/rts or
scheme/bcomp. Watch the run of cvs update carefully and/or subscribe
to the list scsh-checkins@lists.sourceforge.net.


Enjoy!!!
