Building Ion3 under Cygwin

You'll need Ion3 sources, Lua sources.

Building and installing Lua
$ make generic
$ make mingw
$ make install
$ cp src/lua51.dll /usr/local/bin/lua51.dll

Building and installing Ion3
First you need to configure system dependent parameters.
Uncomment following lines in system.mk file:

BIN_SUFFIX = .exe
...
PRELOAD_MODULES=1
...
EXTRA_LIBS += -lintl
...
DEFINES += -DCF_NO_GETLOADAVG

And comment this line:
EXTRA_LIBS += -lrt

Now we are ready to compile and install Ion3 under Cygwin
$ make && make install

Since symbolic links in Cygwin replaced with Windows shortcuts, Ion3 cannot find look.lua and will start without decorations.
To fix this you can copy look_newviolet.lua file in look.lua:

$ cd /usr/local/etc/ion3
$ cp look_newviolet.lua look.lua



Running X server with Ion3
To run X server with Ion3 as window manager I used this bash script:

X -nodecoration -keyhook -clipboard > /dev/null 2>&1 &
ion3 -display :0.0
