This is the root directory for the Scheme-to-C compiler which was done at
Digital Equipment Corporation's Western Research Laboratory.
Changes from the previous release are noted in the file CHANGES found in this
directory.
The compiler distribution consists of several directories:
doc contains documentation.
gnuemacs contains emacs lisp code.
ports contains implementation specific files.
scrt contains the runtime system.
scsc contains the compiler.
test contains compiler and runtime test programs.
cdecl a C declaration compiler written in Scheme.
xlib X11 Xlib stubs for Scheme->C.
In order to install the compiler and interpreter on a system, the following
steps must be done. These instructions assume you're working on a
workstation with a "unix-like" operating system such as a DECstation 5000
running ULTRIX.
1. Verify that this directory contains the previously mentioned directories.
2. Create directories for the processor(s) desired:
For Alpha AXP OSF/1:
1 > make forAOSF
For Apple Macintosh system 7.1 with Think-C 5.0:
1 > make forMAC
For ULTRIX DECstations:
1 > make forDECMIPS
For SGI systems based on Rx000 MIPS processors:
1 > make forSGIMIPS
For ULTRIX VAX systems:
1 > make forVAX
For Microsoft Windows 3.1 with Microsoft C 7.0:
1 > make forWIN16
3. Build Scheme->C for a specific processor:
For Alpha AXP OSF/1:
2 > cd AOSF;make port
N.B.: During the compilation, uopt warnings of the form "this procedure
not optimized because it exceeds size threshold" may occur. These
warnings may be ignored.
For Apple Macintosh system 7.1 with Think-C 5.0:
No further steps are done on the workstation. Follow the
instructions in MAC/README to transfer files to a Macintosh
and complete the build.
For ULTRIX DECstations:
2 > cd DECMIPS;make port
N.B.: During the compilation, uopt warnings of the form "this procedure
not optimized because it exceeds size threshold" may occur. These
warnings may be ignored.
For SGI systems:
2 > cd SGIMIPS;make port
N.B.: During the compilation, uopt warnings of the form "this procedure
not optimized because it exceeds size threshold" may occur. These
warnings may be ignored.
For VAX systems:
2 > cd VAX;make port
N.B.: During the compilation of scrt/scinit.c, one will get the
warnings:
"scinit.c", line 314: warning: illegal pointer combination
"scinit.c", line 316: warning: illegal pointer combination
"scinit.c", line 318: warning: illegal pointer combination
They may be ignored.
During the compilation of scrt/objects.c, one will get the following
warnings:
"objects.c", line 605: warning: illegal pointer combination
"objects.c", line 611: warning: illegal pointer combination
"objects.c", line 614: warning: illegal pointer combination
"objects.c", line 619: warning: illegal pointer combination
"objects.c", line 622: warning: illegal pointer combination
They may be ignored.
For Microsoft Windows 3.1 with Microsoft C 7.0:
No further steps are done on the workstation. Follow the
instructions in WIN16/README to transfer files to a PC and
complete the build.
4. Verify that the interpreter and compiler were correctly built:
4 >cd test
5 >../scrt/sci
SCHEME->C -- ...
> (load "test51.sc")
MODULE form ignored
TEST51
"test51.sc"
> (test51 '())
Hello world!
#F
> ^D
6 >make test51
../scsc/sccomp -schf ../scsc/sccomp.heap -C test51.sc
test51.sc:
../scsc/sccomp -schf ../scsc/sccomp.heap -c -g test51.c
cc -o test51 -g test51.o ../scrt/libsc.a -lm
7 >test51
Hello world!
5. Install the libraries, compiler, and interpreter in some directory
such as ~/bin:
8 >cd ..
9 >make "DESTDIR = /udir/`whoami`/bin" install-private
10 >rehash
Given that this directory in the current search path, the compiler can
now be accessed by "scc" and the interpreter by "sci".
N.B. Some users will see two or three sequences of error messages
ending with "*** Error code 1 (ignored)." These errors may be ignored.
6. At this point, the source in cdecl and xlib can now be compiled if
desired:
11 > cd cdecl
12 > make all
13 > cd ../xlib
14 > make all
Documentation for cdecl and xlib is contained in files found in their
respective directories.
7. If desired, the embedded server sample program and library is
constructed as follows:
15 > cd ../server
16 > make embedded libscsrv.a
