Using the gnu autotools with compiled code

This builds on Generating the smallest possible, self-contained executable and adds support for using the GNU Autotools (autoconf, automake, etc.).

Again, we start with our simple hello.scm:

$ cat hello.scm
(display "Hello, world!\n")
$ chicken hello.scm -explicit-use -uses library

Now we copy library.c, runtime.c and chicken.h from the CHICKEN source distribution into the current directory.

Next we need a Makefile.am and configure.in:

$ cat Makefile.am
bin_PROGRAMS = hello
hello_SOURCES = hello.c runtime.c library.c
hello_LDADD = -lm
$ cat configure.in
AC_INIT(hello, 1.0.0)
AM_INIT_AUTOMAKE()
AC_CONFIG_SRCDIR([[chicken.h)
AC_CONFIG_HEADER([[chicken-config.h)
# Checks for programs.
AC_PROG_CC
# Checks for header files.
AC_FUNC_ALLOCA
AC_HEADER_STDC
AC_HEADER_SYS_WAIT
AC_CHECK_HEADERS([[alloca.a stdint.h limits.h malloc.h stdint.h stdlib.h string.h sys/time.h)
# Checks for typedefs, structures, and compiler characteristics.
AC_C_CONST
AC_TYPE_SIZE_T
AC_HEADER_TIME
AC_STRUCT_TM
AC_C_VOLATILE
# Checks for library functions.
AC_FUNC_MALLOC
AC_FUNC_REALLOC
AC_TYPE_SIGNAL
AC_FUNC_STAT
AC_CHECK_FUNCS([[floor memset modf pow strerror strncasecmp strpbrk)
AC_CONFIG_FILES([[Makefile)
AC_OUTPUT

(This is mostly generated by autoscan)

You should now have the following files:

Makefile.am  
chicken.h  
configure.in  
hello.c  
library.c  
runtime.c

Running a few autotools in the appropriate order, we generate the rest of the required infrastructure:

$ aclocal
$ autoheader
$ automake --foreign -a --copy
configure.in: installing `./install-sh'
configure.in: installing `./mkinstalldirs'
configure.in: installing `./missing'
Makefile.am: installing `./depcomp'
$ autoconf

Now you could put all files in the directory into a tarball and install it on most UNIX machines (For more exotic platforms, some tweaking of configure.in might be needed, though).

Build and installation can now be performed in the usual manner:

$ ./configure
$ make
$ make install
