About
G-Wrap is a tool (and Guile library) for generating function wrappers for inter-language calls. It currently only supports generating Guile wrappers for C functions.
G-Wrap is currently used in GnuCash, guile-gnome and DistWork.
You can find a bug tracker, and mailing list information on the Savannah project page.
G-Wrap has already undergone two major overhauls; the most recent one resulted in the 1.9 unstable series, which will lead to G-Wrap 2.0.
Download
The G-Wrap releases up to 1.3.4 are available from http://ftp.gnucash.org/pub/g-wrap/source/.
The 1.9.x series of releases can be found on http://savannah.nongnu.org/download/g-wrap/.

Changes from 1.9.6:
- The shared libraries now reside in $(pkglibdir)/modules
(e.g. /usr/lib/g-wrap/modules).
- Users are now allowed to chose in which module generic functions
should be defined.
- New feature: aggregated typespecs. See the node `Wrapping a C
Function' of the manual for details.
- Users can now specify a free and a mark function, as well as an
equality predicate for wrapped C types (WCTs) in `wrap-as-wct!'.
- Improved documentation with an API reference (yet to be finished).
- Several bugfixes.

Changes form 1.9.5:
- Support for size_t and ssize_t data types.
1.9.5
Released files, with md5sum:
a8b0da86fe723aeb1694f2d149991300 g-wrap-1.9.5.tar.gz 391bdba6d7c0f1ea87a63623f0b62243 g-wrap-1.9.5.tar.gz.sig
Changes from 1.9.4:
- Bugfixes
+ The minimal GLib wrappers are now installed as (g-wrap gw-glib),
as expected by GnuCash.
+ A problem with generic specializer class lookup has been fixed.
+ A problem with generics specialization and default arguments has
been fixed.
+ A problem with default arguments, when combined with
invisible arguments (such as output arguments) has been fixed.
1.9.4
Released files, with md5sum:
d843c9b1aac9a2960de765cf736c56fb g-wrap-1.9.4.tar.gz 8eab22a61e4077dddbcf913b988091d0 g-wrap-1.9.4.tar.gz.sig
Changes from 1.9.3:
- Enhanced generics support: now all arguments of methods are
specialized, not only the first one.
- Bugfixes
+ Now ships with (g-wrap gw-wct) compatibilty module needed by
GnuCash at runtime.
+ Fixes for handling output arguments:
- Wrapped functions with void return value and output arguments
now return expected results
- Optional argument count is now correctly computed in the
presence of output arguments
+ The libffi alignment requirements are now honored. This fixes bus
errors on many non-x86 architectures.
+ On big-endian architectures libffi-wrapped functions that return
char now work correctly.
+ Some "uninitialized variable" warnings were fixed in generated code
which caused compiles with GCC 4.0 to fail (Debian Bug#290305).
1.9.3
Released files, with md5sum:
53c1ac85c4b88aacb781cd08ed8c7046 g-wrap-1.9.3.tar.gz fe27e2f07f5025193fbbe7287ab1a0ed g-wrap-1.9.3.tar.gz.sig
Changes from 1.9.2:
- Comes with a compatibility layer that allows GnuCash to be built
with it.
- Reverts the enhanced generics support, which was introduced in
1.9.2, since that currently breaks guile-gnome.
- Bugfixes
+ g-wrap-2.0-guile.pc is now generated correctly, even if the
internal libffi is used.
+ Types used by constants are now considered when calculating the
set of referenced types in a wrapset. This bug led to missing code
and compile errors when a type defined in another wrapset was used
by only by a constant.
+ On platforms which lack alloca(), the version shipped with
G-Wrap should now build correctly.
