25.4.2 A Makefile.am for DLLs

First of all we will autoconfiscate(66) the source files above with a minimal setup:

`Makefile.am' is used to generate the `Makefile.in' template for the `configure' script:
 
## Process this file with automake to produce Makefile.in.

lib_LTLIBRARIES		= libhello.la
libhello_la_SOURCES     = hello.c
libhello_la_LDFLAGS     = -no-undefined -version-info 0:0:0

include_HEADERS         = hello.h

bin_PROGRAMS            = hello
hello_SOURCES           = main.c
hello_LDADD             = libhello.la

The new feature introduced in this file is the use of the `-no-undefined' flag in the libhello_la_LDFLAGS value. This flag is required for Windows DLL builds. It asserts to the linker that there are no undefined symbols in the `libhello.la' target, which is one of the requirements for building a DLL outlined earlier. See section 11.2.1 Creating Libtool Libraries with Automake.

For an explanation of the contents of the rest of this `Makefile.am', See section Introducing GNU automake.
