This HOWTO outlines a method for compiling libartnet on Windows using MinGW (libartnet-1.dll). The instructions here http://www.mingw.org/wiki/MSYS are helpful.

you'll need msys, mingw and autotools installed.

         o autoconf [1] 
         o automake [2]
         o libtool [3]

• Unpack autoconf, automake and libtool to a directory of your choice.

• Install them with the 3 with the following command:

../path/to/configure --prefix=/mingw && make && make install

As all the libraries will be installed in /mingw, PKG_CONFIG_PATH must be set.

Open the file /etc/profile (C:\msys\1.0\etc\profile) with your favorite editor (make sure it uses LF line endings) and add:

PKG_CONFIG_PATH="/mingw/lib/pkgconfig"

You might also want to set CFLAGS. Safe options for MinGW are:

CFLAGS="-pipe -O2 -mms-bitfields -march=i686"

just before

export HOME LOGNAME MSYSTEM HISTFILE

and modify that line by adding the variables:

export HOME LOGNAME MSYSTEM HISTFILE CFLAGS PKG_CONFIG_PATH

Now restart MSYS. You should now be able to use MSYS without problems.

(taken from http://www.mingw.org/wiki/msys)

This is the biggest part of the job.

Download Libartnet

Sources (via git) - this will download latest libartnet version

git clone http://www.nomis52.net/git/libartnet

CHECK

check that AC_LIBTOOL_WIN32_DLL macro is present in libartnet/configure.in

if not, add AC_LIBTOOL_WIN32_DLL macro before AC_PROG_LIBTOOL

         o AC_PROG_CC 
         o AC_PROG_INSTALL
         o AC_PROG_LN_S
         o AC_PROG_MAKE_SET
         o AC_LIBTOOL_WIN32_DLL
         o AC_PROG_LIBTOOL

i did this with Bloc-notes because the way the file is recorded is important. you don't want \cr\lf end of lines, you just want \lf. otherwise, you'll get errors like

' is already registered with AC_CONFIG_FILES. ../../lib/autoconf/status.m4:305: AC_CONFIG_FILES is expanded from... configure.in:76: the top level

edit libartnet/artnet/Makefile.am, and check if libartnet_la_LDFLAGS look like this

libartnet_la_LDFLAGS = -no-undefined -liphlpapi -lnetapi32 -lcap -lws2_32 -ldpnet -version-info 1:0:0

or

if USING_WIN32
libartnet_la_LDFLAGS += -no-undefined -liphlpapi -lnetapi32 -lcap -lws2_32 \
                       -ldpnet
endif

Build

now go to libartnet

$ cd libartnet

launch reconf script (autotools where installed in/c/MinGW, so i pass this prefix)

$ reconf --prefix=/c/MinGW/
configure.in:14: installing `./config.guess'
configure.in:14: installing `./config.sub'
configure.in:7: installing `./install-sh'
configure.in:15: required file `./ltmain.sh' not found
configure.in:7: installing `./missing'
artnet/Makefile.am: installing `./depcomp'

libtoolize everything to copy ./ltmain.sh

$ libtoolize --force --copy
libtoolize: putting auxiliary files in `.'.
libtoolize: copying file `./ltmain.sh'
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

(i didn't set AC_CONFIG_MACRO_DIR([m4]) neither ACLOCAL_AMFLAGS)

re-launch reconf script

$ reconf --prefix=/c/MinGW/

compile everything

$ ./configure --prefix=/c/MinGW/ && make && make install

AC_PROG_LIBTOOL macro and -no-undefined flag cause libartnet to build as DLL
