-2.2 SLIB
-========
+2.1 Distributions
+=================
 
-[SLIB] is a portable Scheme library meant to provide compatibility and
-utility functions for all standard Scheme implementations.  Although
-SLIB is not _neccessary_ to run SCM, I strongly suggest you obtain and
-install it.  Bug reports about running SCM without SLIB have very low
-priority.  SLIB is available from the same sites as SCM:
+The SCM homepage contains links to precompiled binaries and source
+distributions.
 
-   * swiss.csail.mit.edu:/pub/scm/slib-3b1.tar.gz
+Downloads and instructions for installing the precompiled binaries are
+at `http://people.csail.mit.edu/jaffer/SCM#QuickStart'.
 
-   * ftp.gnu.org:/pub/gnu/jacal/slib-3b1.tar.gz
+If there is no precompiled binary for your platform, you may be able to
+build from the source distribution.  The rest of these instructions
+deal with building and installing SCM and SLIB from sources.
 
-Unpack SLIB (`tar xzf slib-3b1.tar.gz' or `unzip -ao slib-3b1.zip') in
-an appropriate directory for your system; both `tar' and `unzip' will
-create the directory `slib'.
+Download (both SCM and SLIB of) either the last release or current
+development snapshot from
+`http://people.csail.mit.edu/jaffer/SCM#BuildFromSource'.
 
-Then create a file `require.scm' in the SCM "implementation-vicinity"
-(this is the same directory as where the file `Init5e5.scm' is
-installed).  `require.scm' should have the contents:
+Unzip both the SCM and SLIB zips.  For example, if you are working in
+`/usr/local/src/', this will create directories `/usr/local/src/scm/'
+and `/usr/local/src/slib/'.
 
-     (define (library-vicinity) "/usr/local/lib/slib/")
 
-where the pathname string `/usr/local/lib/slib/' is to be replaced by
-the pathname into which you installed SLIB.  Absolute pathnames are
-recommended here; if you use a relative pathname, SLIB can get confused
-when the working directory is changed (*note chmod: I/O-Extensions.).
-The way to specify a relative pathname is to append it to the
-implementation-vicinity, which is absolute:
 
-     (define library-vicinity
-       (let ((lv (string-append (implementation-vicinity) "../slib/")))
-         (lambda () lv)))
+File: scm-5f2.info,  Node: GNU configure and make,  Next: Building SCM,  Prev: Distributions,  Up: Installing SCM
 
-Alternatively, you can set the (shell) environment variable
-`SCHEME_LIBRARY_PATH' to the pathname of the SLIB directory (*note
-SCHEME_LIBRARY_PATH: SCM Variables.).  If set, the environment variable
-overrides `require.scm'.  Again, absolute pathnames are recommended.
+2.2 GNU configure and make
+==========================
+
+`scm/configure' and `slib/configure' are Shell scripts which create the
+files `scm/config.status' and `slib/config.status' on Unix and MinGW
+systems.
+
+The `config.status' files are used (included) by the Makefile to
+control where the packages will be installed by `make install'.  With
+GNU shell (bash) and utilities, the following commands should build and
+install SCM and SLIB:
+
+     bash$ (cd slib; ./configure --prefix=/usr/local/)
+     bash$ (cd scm
+     > ./configure --prefix=/usr/local/
+     > make scmlit
+     > sudo make all
+     > sudo make install)
+     bash$ (cd slib; sudo make install)
+
+If the install commands worked, skip to *note Testing::.
+
+If `configure' doesn't work on your system, make `scm/config.status'
+and `slib/config.status' be empty files.
+
+For additional help on using the `configure' script, run
+`./configure --help'.
+
+`make all' will attempt to create a dumped executable (*note Saving
+Executable Images::), which has very small startup latency.  If that
+fails, it will try to compile an ordinary `scm' executable.
+
+Note that the compilation output may contain error messages; be
+concerned only if the `make install' transcripts contain errors.
+
+`sudo' runs the command after it as user "root".  On recent GNU/Linux
+systems, dumping requires that `make all' be run as user root; hence
+the use of `sudo'.
 
+`make install' requires root privileges if you are installing to
+standard Unix locations as specified to (or defaulted by)
+`./configure'.  Note that this is independent of whether you did
+`sudo make all' or `make all'.

-     Typing `(e)' will invoke the editor with the file of interest.
-     After editing, the modified file will be loaded.
+2.2.2 Makefile targets
+----------------------
+
+Each of the following four `make' targets creates an executable named
+`scm'.  Each target takes its build options from a file with an `.opt'
+suffix.  If that options file doesn't exist, making that target will
+create the file with the `-F' features: cautious, bignums, arrays,
+inexact, engineering-notation, and dynamic-linking.  Once that `.opt'
+file exists, you can edit it to your taste and it will be preserved.
+
+`make scm4'
+     Produces a R4RS executable named `scm' lacking hygienic macros
+     (but with defmacro).  The build options are taken from `scm4.opt'.
+     If build or the executable fails, try removing `dynamic-linking'
+     from `scm4.opt'.
+
+`make scm5'
+     R5RS; like `make scm4' but with `-F macro'.  The build options are
+     taken from `scm5.opt'.  If build or the executable fails, try
+     removing `dynamic-linking' from `scm5.opt'.
+
+`make dscm4'
+     Produces a R4RS executable named `udscm4', which it starts and
+     dumps to a low startup latency executable named `scm'.  The build
+     options are taken from `udscm4.opt'.
+
+     If the build fails, then `build scm4' instead.  If the dumped
+     executable fails to run, then send me a bug report (and use
+     `build scm4' until the problem with dump is corrected).
+
+`make dscm5'
+     Like `make dscm4' but with `-F macro'.  The build options are
+     taken from `udscm5.opt'.
+
+     If the build fails, then `build scm5' instead.  If the dumped
+     executable fails to run, then send me a bug report (and use
+     `build scm5' until the problem with dump is corrected).
+
+
+If the above builds fail because of `-F dynamic-linking', then (because
+they can't be dynamically linked) you will likely want to add some
+other features to the build's `.opt' file.  See the `-F' build option
+in *note Build Options::.
+
+If dynamic-linking is working, then you will likely want to compile
+most of the modules as "DLL"s.  The build options for compiling DLLs
+are in `dlls.opt'.
+
+`make x.so'
+     The `Xlib' module; *note SCM Language X Interface: (Xlibscm)Top.
+
+`make myturtle'
+     Creates a DLL named `turtlegr.so' which is a simple graphics API.
+
+`make wbscm.so'
+     The `wb' module; *note B-tree database implementation: (wb)Top.
+     Compiling this requires that wb source be in a peer directory to
+     scm.
+
+`make dlls'
+     Compiles all the distributed library modules, but not `wbscm.so'.
+     Many of the module compiles are recursively invoked in such a way
+     that failure of one (which could be due to a system library not
+     being installed) doesn't cause the top-level `make dlls' to fail.
+     If `make dlls' fails as a whole, it is time to submit a bug report
+     (*note Reporting Problems::).

+2.3.1 Invoking Build
+--------------------
+
+This section teaches how to use `build', a Scheme program for creating
+compilation scripts to produce SCM executables and library modules.
+The options accepted by `build' are documented in *note Build Options::.
+
+Use the _any_ method if you encounter problems with the other two
+methods (MS-DOS, Unix).
+
+MS-DOS
+     From the SCM source directory, type `build' followed by up to 9
+     command line arguments.
+
+Unix
+     From the SCM source directory, type `./build' followed by command
+     line arguments.
+
+_any_
+     From the SCM source directory, start `scm' or `scmlit' and type
+     `(load "build")'.  Alternatively, start `scm' or `scmlit' with the
+     command line argument `-ilbuild'.  This method will also work for
+     MS-DOS and Unix.
+
+     After loading various SLIB modules, the program will print:
+
+          type (b "build <command-line>") to build
+          type (b*) to enter build command loop
+
+     The `b*' procedure enters into a "build shell" where you can enter
+     commands (with or without the `build').  Blank lines are ignored.
+     To create a build script with all defaults type `build'.
+
+     If the build-shell encouters an error, you can reenter the
+     build-shell by typing `(b*)'.  To exit scm type `(quit)'.
+
+
+Here is a transcript of an interactive (b*) build-shell.

+ -- Build Option: -f PATHNAME
+     specifies that the build options contained in PATHNAME be spliced
+     into the argument list at this point.  The use of option files can
+     separate functional features from platform-specific ones.
+
+     The `Makefile' calls out builds with the options in `.opt' files:
+
+    `dlls.opt'
+          Options for Makefile targets dlls, myturtle, and x.so.
+
+    `gdb.opt'
+          Options for udgdbscm and gdbscm.
+
+    `libscm.opt'
+          Options for libscm.a.
+
+    `pg.opt'
+          Options for pgscm, which instruments C functions.
+
+    `udscm4.opt'
+          Options for targets udscm4 and dscm4 (scm).
+
+    `udscm5.opt'
+          Options for targets udscm5 and dscm5 (scm).
+
+     The Makefile creates options files it depends on only if they do
+     not already exist.
+
+ -- Build Option: -o FILENAME
+ -- Build Option: --outname=FILENAME
+     specifies that the compilation should produce an executable or
+     object name of FILENAME.  The default is `scm'.  Executable
+     suffixes will be added if neccessary, e.g. `scm' => `scm.exe'.
+
+ -- Build Option: -l LIBNAME ...
+ -- Build Option: --libraries=LIBNAME
+     specifies that the LIBNAME should be linked with the executable
+     produced.  If compile flags or include directories (`-I') are
+     needed, they are automatically supplied for compilations.  The `c'
+     library is always included.  SCM "features" specify any libraries
+     they need; so you shouldn't need this option often.
+
+ -- Build Option: -D DEFINITION ...
+ -- Build Option: --defines=DEFINITION
+     specifies that the DEFINITION should be made in any C source
+     compilations.  If compile flags or include directories (`-I') are
+     needed, they are automatically supplied for compilations.  SCM
+     "features" specify any flags they need; so you shouldn't need this
+     option often.
+
+ -- Build Option: --compiler-options=FLAG
+     specifies that that FLAG will be put on compiler command-lines.
+
+ -- Build Option: --linker-options=FLAG
+     specifies that that FLAG will be put on linker command-lines.
+
+ -- Build Option: -s PATHNAME
+ -- Build Option: --scheme-initial=PATHNAME
+     specifies that PATHNAME should be the default location of the SCM
+     initialization file `Init5f1.scm'.  SCM tries several likely
+     locations before resorting to PATHNAME (*note File-System
+     Habitat::).  If not specified, the current directory (where build
+     is building) is used.
+
+ -- Build Option: -c PATHNAME ...
+ -- Build Option: --c-source-files=PATHNAME
+     specifies that the C source files PATHNAME ... are to be compiled.
+
+ -- Build Option: -j PATHNAME ...
+ -- Build Option: --object-files=PATHNAME
+     specifies that the object files PATHNAME ... are to be linked.
+
+ -- Build Option: -i CALL ...
+ -- Build Option: --initialization=CALL
+     specifies that the C functions CALL ... are to be invoked during
+     initialization.
+
+ -- Build Option: -t BUILD-WHAT
+ -- Build Option: --type=BUILD-WHAT
+     specifies in general terms what sort of thing to build.  The
+     choices are:
+    `exe'
+          executable program.
+
+    `lib'
+          library module.
+
+    `dlls'
+          archived dynamically linked library object files.
+
+    `dll'
+          dynamically linked library object file.
+
+     The default is to build an executable.
+
+ -- Build Option: -h BATCH-SYNTAX
+ -- Build Option: -batch-dialect=BATCH-SYNTAX
+     specifies how to build.  The default is to create a batch file for
+     the host system.  The SLIB file `batch.scm' knows how to create
+     batch files for:
+        * unix
+
+        * dos
+
+        * vms
+
+        * amigaos (was amigados)
+
+        * system
+
+          This option executes the compilation and linking commands
+          through the use of the `system' procedure.
+
+        * *unknown*
+
+          This option outputs Scheme code.
+
+ -- Build Option: -w BATCH-FILENAME
+ -- Build Option: -script-name=BATCH-FILENAME
+     specifies where to write the build script.  The default is to
+     display it on `(current-output-port)'.
+
+ -- Build Option: -F FEATURE ...
+ -- Build Option: --features=FEATURE
+     specifies to build the given features into the executable.  The
+     defined features are:
+
+    "array"
+          Alias for ARRAYS
+
+    "array-for-each"
+          array-map! and array-for-each (arrays must also be featured).
+
+    "arrays"
+          Use if you want arrays, uniform-arrays and uniform-vectors.
+
+    "bignums"
+          Large precision integers.
+
+    "byte"
+          Treating strings as byte-vectors.
+
+    "byte-number"
+          Byte/number conversions
+
+    "careful-interrupt-masking"
+          Define this for extra checking of interrupt masking and some
+          simple checks for proper use of malloc and free.  This is for
+          debugging C code in `sys.c', `eval.c', `repl.c' and makes the
+          interpreter several times slower than usual.
+
+    "cautious"
+          Normally, the number of arguments arguments to interpreted
+          closures (from LAMBDA) are checked if the function part of a
+          form is not a symbol or only the first time the form is
+          executed if the function part is a symbol.  defining
+          `reckless' disables any checking.  If you want to have SCM
+          always check the number of arguments to interpreted closures
+          define feature `cautious'.
+
+    "cheap-continuations"
+          If you only need straight stack continuations, executables
+          compile with this feature will run faster and use less
+          storage than not having it.  Machines with unusual stacks
+          _need_ this.  Also, if you incorporate new C code into scm
+          which uses VMS system services or library routines (which
+          need to unwind the stack in an ordrly manner) you may need to
+          use this feature.
+
+    "compiled-closure"
+          Use if you want to use compiled closures.
+
+    "curses"
+          For the "curses" screen management package.
+
+    "debug"
+          Turns on the features `cautious' and
+          `careful-interrupt-masking'; uses `-g' flags for debugging
+          SCM source code.
+
+    "differ"
+          Sequence comparison
+
+    "dont-memoize-locals"
+          SCM normally converts references to local variables to ILOCs,
+          which make programs run faster.  If SCM is badly broken, try
+          using this option to disable the MEMOIZE_LOCALS feature.
+
+    "dump"
+          Convert a running scheme program into an executable file.
 
+    "dynamic-linking"
+          Be able to load compiled files while running.
 
+    "edit-line"
+          interface to the editline or GNU readline library.

+          (exponents always multiples of 3) instead of scientific
+          notation.

+          Press, Cambridge, Massachusetts, USA, 1985.
+
+          Differences from R5RS are:
+             * (eq? '() '#f)
+
+             * (define a 25) returns the symbol a.
+
+             * (set! a 36) returns 36.
+
+    "single-precision-only"

+
+2.4 Saving Executable Images
+============================
+
+In SCM, the ability to save running program images is called "dump"
+(*note Dump::).  In order to make `dump' available to SCM, build with
+feature `dump'.  `dump'ed executables are compatible with dynamic
+linking.
+
+Most of the code for "dump" is taken from `emacs-19.34/src/unex*.c'.
+No modifications to the emacs source code were required to use
+`unexelf.c'.  Dump has not been ported to all platforms.  If `unexec.c'
+or `unexelf.c' don't work for you, try using the appropriate `unex*.c'
+file from emacs.
+
+The `dscm4' and `dscm5' targets in the SCM `Makefile' save images from
+`udscm4' and `udscm5' executables respectively.
+
+"Address space layout randomization" interferes with `dump'.  Here are
+the fixes for various operating-systems:
+
+Fedora-Core-1
+     Remove the `#' from the line `#SETARCH = setarch i386' in the
+     `Makefile'.
+
+Fedora-Core-3
+     `http://jamesthornton.com/writing/emacs-compile.html' [For FC3]
+     combreloc has become the default for recent GNU ld, which breaks
+     the unexec/undump on all versions of both Emacs and XEmacs...
+
+     Override by adding the following to `udscm5.opt':
+     `--linker-options="-z nocombreloc"'
+
+Linux Kernels later than 2.6.11
+`http://www.opensubscriber.com/message/emacs-devel@gnu.org/1007118.html'
+     mentions the "exec-shield" feature.  Kernels later than 2.6.11
+     must do (as root):
+
+          echo 0 > /proc/sys/kernel/randomize_va_space
+
+     before dumping.  `Makefile' has this `randomize_va_space' stuffing
+     scripted for targets `dscm4' and `dscm5'.  You must either set
+     `randomize_va_space' to 0 or run as root to dump.
+
+OS-X 10.6
+`http://developer.apple.com/library/mac/#documentation/Darwin/Reference/Manpages/man1/dyld.1.html'
+     The dynamic linker uses the following environment variables.  They
+     affect any program that uses the dynamic linker.
+
+     DYLD_NO_PIE
+
+     Causes dyld to not randomize the load addresses of images in a
+     process where the main executable was built position independent.
+     This can be helpful when trying to reproduce and debug a problem
+     in a PIE.

-Sparc(SUN-4) heap is growing out of control
-     You are experiencing a GC problem peculiar to the Sparc.  The
-     problem is that SCM doesn't know how to clear register windows.
-     Every location which is not reused still gets marked at GC time.
-     This causes lots of stuff which should be collected to not be.
-     This will be a problem with any _conservative_ GC until we find
-     what instruction will clear the register windows.  This problem is
-     exacerbated by using lots of call-with-current-continuations.  A
-     possible fix for dynthrow() is commented out in `continue.c'.

+2.6.6 Reporting Problems
+------------------------
+
+Reported problems and solutions are grouped under Compiling, Linking,
+Running, and Testing.  If you don't find your problem listed there, you
+can send a bug report to `agj@alum.mit.edu' or `scm-discuss@gnu.org'.
+The bug report should include:
+
+  1. The version of SCM (printed when SCM is invoked with no arguments).
+
+  2. The type of computer you are using.
+
+  3. The name and version of your computer's operating system.
+
+  4. The values of the environment variables `SCM_INIT_PATH' and
+     `SCHEME_LIBRARY_PATH'.
+
+  5. The name and version of your C compiler.
+
+  6. If you are using an executable from a distribution, the name,
+     vendor, and date of that distribution.  In this case,
+     corresponding with the vendor is recommended.

+
+3.7 Editing Scheme Code
+=======================
+
+ -- Function: ed arg1 ...
+     The value of the environment variable `EDITOR' (or just `ed' if it
+     isn't defined) is invoked as a command with arguments ARG1 ....
+
+ -- Function: ed filename
+     If SCM is compiled under VMS `ed' will invoke the editor with a
+     single the single argument FILENAME.
+
+Gnu Emacs:
+     Editing of Scheme code is supported by emacs.  Buffers holding
+     files ending in .scm are automatically put into scheme-mode.
+
+     If your Emacs can run a process in a buffer you can use the Emacs
+     command `M-x run-scheme' with SCM.  Otherwise, use the emacs
+     command `M-x suspend-emacs'; or see "other systems" below.
+
+Epsilon (MS-DOS):
+     There is lisp (and scheme) mode available by use of the package
+     `LISP.E'.  It offers several different indentation formats.  With
+     this package, buffers holding files ending in `.L', `.LSP', `.S',
+     and `.SCM' (my modification) are automatically put into lisp-mode.
+
+     It is possible to run a process in a buffer under Epsilon.  With
+     Epsilon 5.0 the command line options `-e512 -m0' are neccessary to
+     manage RAM properly.  It has been reported that when compiling SCM
+     with Turbo C, you need to `#define NOSETBUF' for proper operation
+     in a process buffer with Epsilon 5.0.
+
+     One can also call out to an editor from SCM if RAM is at a
+     premium; See "under other systems" below.
+
+other systems:
+     Define the environment variable `EDITOR' to be the name of the
+     editing program you use.  The SCM procedure `(ed arg1 ...)' will
+     invoke your editor and return to SCM when you exit the editor.  The
+     following definition is convenient:
+
+          (define (e) (ed "work.scm") (load "work.scm"))
+
+     Typing `(e)' will invoke the editor with the file of interest.
+     After editing, the modified file will be loaded.
