mwp on cygwin

mwp on Cygwin

From 2015-12-30, it is possible to build and run pretty much all of the mwptools suite in cygwin. It is the best performing Windows option and is the most feature complete.

• Runs from a desktop short cut
• Audio works (sort of)
• Easy device names translation

Installation

• Install the required packages. The file cygwin-example-packages.txt.gz is taken from a cygwin installation that is capable of building and running mwp. Note that while this seems like a large list, many of the items are automagically installed as dependencies of other items. See also Automation Hints below.

• At run time, you need to have started the a X server. MobaXterm is recommended for its stability and performance (and OpenGL hardware suport). VcXsrv works as well. Mobaxterm -hideterm is useful as a Start Menu / Startup option.

• Serial devices must be prefixed /dev/ and are zero indexed, e.g. COM3: => /dev/ttyS2

Once the dependencies are installed, mwp is built from the cygwin shell:

• Clone the repository git clone https://github.com/stronnag/mwptools
• cd mwptools
• one off : meson setup build --buildtype=release --strip --prefix /usr
• ninja -C build install

Automation hints

The dependencies may be installed follows:

• Install the base cygwin package using the graphical installer from cygwin.

• Install a few (additional) packages git, wget and gzip, using the graphical installer.

• Open the cygwin terminal

• Fetch and make executable the apt-cyg script

  wget https://rawgit.com/transcode-open/apt-cyg/master/apt-cyg
  install apt-cyg /bin
  

• Clone the mwp repsoitory

  git clone --depth 1 https://github.com/stronnag/mwptools
  

• Install most of the dependencies in one hit:

  apt-cyg install $(zcat mwptools/docs/cygwin-example-packages.txt.gz)
  

• Reportedly (#120), libgstinterfaces1.0-devel is also required.

• Install ninja and meson (now done by the above package list)

• Build mwp

  cd mwptools
  # one off
  meson setup build --buildtype=release --strip --prefix /usr
  # each build
  ninja -C build install
  

Runtime

For blackbox replay, you need the Windows versions of

• flightlog2kml / fl2ltm
• blackbox_decode

These need to be installed in a place where they can be found by their caller (mwp must be able to find fl2ltm, fl2ltm must be able to find blackbox_decode).

For terrain analysis, Windows versions of:

• mwp-plot-elevations
• gnuplot

It's convenient to set the following in .bash_profile

# This *may* work, otherwise it may be necessary to set DISPLAY to the IP address of the Windows host (export DISPLAY=a.b.c.d:0, where a.b.c.d = IP of Windows host)
export DISPLAY=:0
export NO_AT_BRIDGE=1
# for VcXsvr, MobaXterm does not need it. ***In fact, it will crash mwp with it set****
export LIBGL_ALWAYS_INDIRECT=Y

The X server (MobaXterm, VcXsrv) must be running, it may be convenient to start this automatically from the Windows Startup directory.

A Windows batch file is provided that may be used as a desktop shortcut docs/mwp-cywin.bat; it may need customising.

A Windows icon is provided (src/common/mwp_icon.ico)

In theory, no support is offered for running under cygwin.
