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.
