Libartnet on Windows

Written by sl1200mk2 2009/07/01. (nicole-banana.com)

This HOWTO outlines a method for compiling libartnet on Windows using MinGW to produce the libartnet-1.dll.

Install Mingw, msys & build tools

The instructions at http://www.mingw.org/wiki/MSYS are very helpful.

• Install mingw and msys

• Download these packages
  • autoconf [1]
  • automake [2]
  • libtool [3]

• Launch the msys shell

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

• Install each of them with the following command:

$ ./configure --prefix=/mingw && make && make install

• Update PKG_CONFIG_PATH

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.

This is the biggest part of the job.

Install Git

See http://code.google.com/p/msysgit/, be sure to select "unix style carriage returns" otherwise you'll get autoconf errors.

Download Libartnet

Grab the libarnet sources (via the git shell or the git UI)

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

Compile 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
