This directory contains examples for CHICKEN.
class -- illustrates the proxy class C++ interface
constants -- handling #define and %constant literals
egg -- examples of building chicken extension libraries
multimap -- typemaps with multiple sub-types
overload -- C++ function overloading
simple -- the simple example from the user manual
zlib -- a wrapping of the zlib compression library
You should be able to run make in each of the examples. By default, a shared
library will be built. Run make check to execute the test.

These examples show how to build a chicken extension module in the form of an
egg. There are two eggs that get built, single.egg which contains a single
module which is built with -nounit and multi.egg, which contains two modules
mod1 and mod2. These are built normally, and multi_init.scm loads them both.
Read section "17.4.2 Building chicken extension libraries" in the manual
for a description of these two techniques.
To build:
$ make
$ make setup
$ make run
$ make clean
The eggs are built into an eggs subdirectory, because chicken-setup has
problems installing eggs when there are other files named similar in
the same directory. The make setup step runs chicken-setup to install
the eggs into the eggs/install directory.
