Building TinyScheme
|
|
-------------------
|
|
|
|
The included makefile includes logic for Linux, Solaris and Win32, and can
|
|
readily serve as an example for other OSes, especially Unixes. There are
|
|
a lot of compile-time flags in TinyScheme (preprocessor defines) that can trim
|
|
unwanted features. See next section. 'make all' and 'make clean' function as
|
|
expected.
|
|
|
|
Autoconfing TinyScheme was once proposed, but the distribution would not be
|
|
so small anymore. There are few platform dependencies in TinyScheme, and in
|
|
general compiles out of the box.
|
|
|
|
Customizing
|
|
-----------
|
|
|
|
The following symbols are defined to default values in scheme.h.
|
|
Use the -D flag of cc to set to either 1 or 0.
|
|
|
|
STANDALONE
|
|
Define this to produce a standalone interpreter.
|
|
|
|
USE_MATH
|
|
Includes math routines.
|
|
|
|
USE_CHAR_CLASSIFIERS
|
|
Includes character classifier procedures.
|
|
|
|
USE_ASCII_NAMES
|
|
Enable extended character notation based on ASCII names.
|
|
|
|
USE_STRING_PORTS
|
|
Enables string ports.
|
|
|
|
USE_ERROR_HOOK
|
|
To force system errors through user-defined error handling.
|
|
(see "Error handling")
|
|
|
|
USE_TRACING
|
|
To enable use of TRACING.
|
|
|
|
USE_COLON_HOOK
|
|
Enable use of qualified identifiers. (see "Colon Qualifiers - Packages")
|
|
Defining this as 0 has the rather drastic consequence that any code using
|
|
packages will stop working, and will have to be modified. It should only
|
|
be used if you *absolutely* need to use '::' in identifiers.
|
|
|
|
USE_STRCASECMP
|
|
Defines stricmp as strcasecmp, for Unix.
|
|
|
|
STDIO_ADDS_CR
|
|
Informs TinyScheme that stdio translates "\n" to "\r\n". For DOS/Windows.
|
|
|
|
USE_DL
|
|
Enables dynamically loaded routines. If you define this symbol, you
|
|
should also include dynload.c in your compile.
|
|
|
|
USE_PLIST
|
|
Enables property lists (not Standard Scheme stuff). Off by default.
|
|
|
|
USE_NO_FEATURES
|
|
Shortcut to disable USE_MATH, USE_CHAR_CLASSIFIERS, USE_ASCII_NAMES,
|
|
USE_STRING_PORTS, USE_ERROR_HOOK, USE_TRACING, USE_COLON_HOOK,
|
|
USE_DL.
|
|
|
|
USE_SCHEME_STACK
|
|
Enables 'cons' stack (the alternative is a faster calling scheme, which
|
|
breaks continuations). Undefine it if you don't care about strict compatibility
|
|
but you do care about faster execution.
|
|
|

OS-X tip
|
|
--------
|
|
I don't have access to OS-X, but Brian Maher submitted the following tip:
|
|
|
|
[1] Download and install fink (I installed fink in
|
|
/usr/local/fink)
|
|
[2] Install the 'dlcompat' package using fink as such:
|
|
> fink install dlcompat
|
|
[3] Make the following changes to the
|
|
tinyscheme-1.32.tar.gz
|
|
|
|
diff -r tinyscheme-1.32/dynload.c
|
|
tinyscheme-1.32-new/dynload.c
