We are pleased to announce GNU Guile release 1.8.6. This is the next maintenance release for the 1.8 stable series. It provides a number of portability improvements, bug fixes, as well as several new features.
The Guile web page is located at http://gnu.org/software/guile/, and among other things, it contains a link to the Guile FAQ and pointers to the mailing lists. Guile is an interpreter for the Scheme programming language, with support for many SRFIs, packaged for use in a wide variety of environments. In addition to implementing the R5RS Scheme standard, Guile includes a module system, full access to POSIX system calls, networking support, multiple threads, dynamic linking, a foreign function call interface, and powerful string processing. Guile can run interactively or as a script interpreter, and is also packaged as a library so that applications can easily incorporate a complete Scheme interpreter. An application can use Guile as an extension language, a clean and powerful configuration language, or as multi-purpose "glue" to connect primitives provided by the application. It is easy to call Scheme code from C code and vice versa. Applications can add new functions, data types, control structures, and even syntax to Guile, to create a domain-specific language tailored to the task at hand. Here are the compressed sources: ftp://ftp.gnu.org/gnu/guile/guile-1.8.6.tar.gz (3.8MB) Here are the GPG detached signatures[*]: ftp://ftp.gnu.org/gnu/guile/guile-1.8.6.tar.gz.sig Here are the MD5 and SHA1 checksums: 9e23d3dbea0e89bab8a9acc6880150de guile-1.8.6.tar.gz a3896f86044a2b3740dac43e045c349d656fba31 guile-1.8.6.tar.gz [*] You can use either of the above signature files to verify that the corresponding file (without the .sig suffix) is intact. First, be sure to download both the .sig file and the corresponding tarball. Then, run a command like this: gpg --verify guile-1.8.6.tar.gz.sig If that command fails because you don't have the required public key, then run this command to import it: gpg --keyserver keys.gnupg.net --recv-keys EA52ECF4 and rerun the `gpg --verify' command. This release was bootstrapped with the following tools: Autoconf 2.63 Automake 1.10.1 Libtool 2.2.6 This is primarily a bugfix release. Here are the highlights, taken from the `NEWS' file: * New features (see the manual for details) ** New convenience function `scm_c_symbol_length ()' ** Single stepping through code from Emacs ** New "guile(1)" man page! * Changes to the distribution ** Automake's `AM_MAINTAINER_MODE' is no longer used ** `ChangeLog' files are no longer updated * Bugs fixed ** `symbol->string' now returns a read-only string, as per R5RS ** Fix incorrect handling of the FLAGS argument of `fold-matches' ** `guile-config link' now prints `-L$libdir' before `-lguile' ** Fix memory corruption involving GOOPS' `class-redefinition' ** Fix possible deadlock in `mutex-lock' ** Fix build issue on Tru64 and ia64-hp-hpux11.23 (`SCM_UNPACK' macro) ** Fix build issue on mips, mipsel, powerpc and ia64 (stack direction) ** Fix build issue on hppa2.0w-hp-hpux11.11 (`dirent64' and `readdir64_r') ** Fix build issue on i386-unknown-freebsd7.0 ("break strict-aliasing rules") ** Fix misleading output from `(help rationalize)' ** Fix build failure on Debian hppa architecture (bad stack growth detection) ** Fix `gcd' when called with a single, negative argument. ** Fix `Stack overflow' errors seen when building on some platforms ** Fix bug when `scm_with_guile ()' was called several times from the same thread ** The handler of SRFI-34 `with-exception-handler' is now invoked in the dynamic environment of the call to `raise' ** Fix potential deadlock in `make-struct' ** Fix compilation problem with libltdl from Libtool 2.2.x ** Fix sloppy bound checking in `string-{ref,set!}' with the empty string Any bugs found in this release will be addressed by further bugfix releases numbered 1.8.*. You can follow Guile development in the Git repository and on the Guile mailing lists. Guile builds from the `master' branch of Git will have version number 1.9.0. Guile versions with an odd middle number, e.g., 1.9.*, are unstable development versions. Even middle numbers indicate stable versions. This has been the case since the 1.3.* series. Please report bugs through the Savannah bug tracker: https://savannah.gnu.org/bugs/?group=guile Alternatively, bug reports can be sent to [EMAIL PROTECTED]'. We also welcome reports of successful builds, which can be sent to the same email address. Ludovic Courtès, on behalf of the Guile team.
