-This is a 1.9 development version of Guile, Project GNU's extension
-language library. Guile is an interpreter for Scheme, packaged as a
-library that you can link into your applications to give them their
-own scripting language. Guile will eventually support other languages
-as well, giving users of Guile-based applications a choice of
-languages.
-
-Guile versions with an odd middle number, i.e. 1.9.* are unstable
-development versions. Even middle numbers indicate stable versions.
-This has been the case since the 1.3.* series.

-The next stable release will likely be version 2.0.0.

Additional INSTALL instructions ===========================================
- libunistring
- libgc
- libffi
-It will also use the libreadline library if it is available. For each
-of these there is a corresponding --with-XXX-prefix option that you
-can use when invoking ./configure, if you have these libraries
-installed in a location other than the standard places (/usr and
-/usr/local).

+There is a corresponding `--with-XXX-prefix' option for each of these
+libraries (except for libgc and libffi which use `pkg-config', see
+below) that you can use when invoking ./configure, if you have these
+libraries installed in a location other than the standard places (/usr
+and /usr/local).
These options are provided by the Gnulib `havelib' module, and details
of how they work are documented in `Searching for Libraries' in the
- pkg-config
Guile's ./configure script uses pkg-config to discover the correct
- compile and link options for libgc. If you don't have pkg-config
- installed, or you have a version of libgc that doesn't provide a
- .pc file, you can work around this by setting some variables as
- part of the configure command-line:
+ compile and link options for libgc and libffi. If you don't have
+ pkg-config installed, or you have a version of libgc that doesn't
+ provide a .pc file, you can work around this by setting some
+ variables as part of the configure command-line:
- PKG_CONFIG=true
- BDW_GC_LIBS=<linker flags for picking up the libgc library>
+ Note that because you're bypassing all pkg-config checks, you will
+ also have to specify libffi flags as well:
+
+ - LIBFFI_CFLAGS=<compile flags for picking up libffi headers>
+
+ - LIBFFI_LIBS=<linker flags for picking up the libffi library>

Special Instructions For Some Systems =====================================
implementation and helps to keep Guile reasonably clean of historic
baggage.
- Deprecated features are considered harmful; using them is likely a
- bug. See below for the related notion of `discouraged' features,
- which are OK but have fallen out of favor.
-
See the file NEWS for a list of features that are currently
deprecated. Each entry will also tell you what you should replace
your code with.
'warn-deprecated) to enable and disable the detailed messaged at run
time.
---disable-discouraged
-
- In addition to deprecated features, Guile can also contain things
- that are merely `discouraged'. It is OK to continue to use these
- features in old code, but new code should avoid them since there are
- better alternatives.
-
- There is nothing wrong with a discouraged feature per se, but they
- might have strange names, or be non-standard, for example. Avoiding
- them will make your code better.
+ Additionally, if your toolchain is new enough, you will receive
+ warnings at link time if you have a Guile extension that uses
+ deprecated functions provided by Guile.
--disable-shared --- Do not build shared libraries.
--disable-static --- Do not build static libraries.
Guile Documentation ==================================================
-If you've never used Scheme before, then the Guile Tutorial
-(guile-tut.info) is a good starting point. The Guile Reference Manual
-(guile.info) is the primary documentation for Guile. A copy of the
-R5RS Scheme specification is included too (r5rs.info).
