This describes how to get OLA compiled for windows, it's a work in progress so it's unlikely to work as is. This tutorial uses gcc as the compiler, other compilers have not been tested.

During Google Summer of Code 2014, this port will be worked on as one of the selected projects.

Install Mingw, msys & build tools

Together MinGW & msys provide a unix-style shell environment & compiler suite for windows. Read the instructions at the MinGW site for more info. MinGW now provides an installer to get most of the system up and running quickly. Download the installer and make sure you select "C++ Compiler". "MSYS Basic System" & "MinGW Developer Toolkit" when prompted.

Once the installer has completed, open the msys shell (under Programs > MinGW) and install some additional packages:

$ mingw-get.exe install msys-coreutils mingw32-base mingw32-pthreads-w32 msys-wget

Note that some of these might already have been installed.

Install Git

Git is used to checkout (and commit) the ola sources. See http://code.google.com/p/msysgit/, be sure to select "checkout as is, commit unix style" during the install otherwise you'll get autoconf errors.

Add the following line to your .bashrc file so that git can be used within msys:

PATH="$PATH:/c/Program Files/Git/bin"
alias git=git.exe

If you are on 64bit windows you may need to use:

PATH="$PATH:/c/Program Files (x86)/Git/bin"
alias git=git.exe

Install pkg-config

Download pkg-config-lite from http://sourceforge.net/projects/pkgconfiglite/files/ (the latest binary should work) and extract it to your MinGW directory.

You also need to add

 export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
 CPPFLAGS="-I/usr/local/include"
 LDFLAGS="-L/usr/local/lib"

to your .bashrc file.

[ -f ~/.bashrc ] && . ~/.bashrc

If you haven't configured your MSYS fstab yet, do that as well. See http://www.mingw.org/wiki/Getting_Started for instructions.

Build OLA

• Do a git checkout of OLA

 $ git.exe clone https://github.com/OpenLightingProject/ola.git

• Prepare autotools files

 $ autoreconf -i -f

• Run ./configure

 $ ./configure --enable-python-libs --disable-e131 --disable-karate --disable-milinst --disable-renard --disable-spi --disable-stageprofi --disable-usbpro --disable-usbdmx --disable-uart

• Build

 $ make

• Optional: Run the tests

 $ make check

• Install

 $ make install

Current State / TODO

See the GSOC project page.

Misc Notes

You may run into issues with the latest mingw and protobufs. During runtime it can't find libstdc++-6.dll. Attempt to follow this and see if any of the solutions fixes your problem. We'd love to hear the outcome on irc or the forums. http://stackoverflow.com/questions/6404636/libstdc-6-dll-not-found

Sean Sill: I ended up removing libstdc++.dll.a from the C:/MinGW/libs folder.
