Setting up the waf Build Environment on Windows using Cygwin¶
These setup instructions describe how to setup Cygwin on so that waf (the build system) can run natively on windows and build for all supported boards.
open a web browser to www.cygwin.com/install.html and select “Run setup-x86_64.exe”
accept the all the prompts (including default file locations) until you reach the Select Packages dialog.
Select the required packages from the thousands of available packages. Refer to the list below and enter each package “Name” into the Search field as shown below. When you have found the package click on the Skip button to change it to a version number and then move onto the next package:
Package Name Category / Name / Description autoconf Devel | autoconf: Wrapper scripts for autoconf commands automake Devel | automake: Wrapper scripts for automake and aclocal ccache Devel | ccache: A C compiler cache for improving recompilation gcc-g++ Devel | gcc-g++ GNU Compiler Collection (C++) git Devel | git: Distributed version control system libtool Devel | libtool: Generic library support script make Devel | make: The GNU version of the ‘make’ utility gawk Interpreters | gawk: GNU awk, a pattern scanning and processing language libexpat-devel Libs | libexpat-devel: Expat XML parser library (development files) libxml2-devel Libs | libxml2-devel: Gnome XML library (development) libxslt-devel Libs | libxslt-devel: XML template library (development files) python2-devel Python | python2-devel: Python2 language interpreter (python3 does not work yet) python2-future Python | python2-future: Clean single-source support for Python 3 and 2 python2-libxml2 Python | python2-libxml2: Gnome XML Library (Python bindings python2-pip Python | python2-pip: Python package installation tool procps-ng System | procps-ng: System and process monitoring utilities (required for pkill) gdb Devel | gdb: The GNU Debugger ddd Devel | ddd: DDD, the data display debugger zip Archive | zip: Info-ZIP compression utility
Or you can run
setup-x86_64.exe -P autoconf,automake,ccache,gcc-g++,git,libtool,make,gawk,libexpat-devel,libxml2-devel,libxslt-devel,python2-devel,python2-future,python2-libxml2,python2-pip,procps-ng,gdb,ddd,zip
When all the packages are selected, click through the rest of the prompts and accept all other default options (including the additional dependencies).
Select Finish to start downloading and installing the packages.
Sometimes the installation can stall because of anti-virus protection software is running. If this occurs, shutdown all other programs on your PC including the anti-virus protection and try again.
Install the GCC compiler¶
The MAVProxy GCS is required when running SITL. If you’re not planning to run SITL, you can skip this step.
- To install MAVProxy on Windows follow the MAVProxy’s install instructions for Windows
Set up directories/paths and extra packages in Cygwin¶
- open and then close the “Cygwin64 Terminal” application from the desktop or start menu icon. This creates initialisation files for the user in the Cygwin home directory.
- open the “Cygwin64 Terminal” application from the desktop or start menu icon. Enter the following command to install additional Python packages:
pip2 install empy pip2 install pyserial pip2 install pymavlink
Build with Waf¶
You should now be able to start the “Cygwin64 Terminal” application from your Windows Start menu and build with waf as described in BUILD.md.
The build may fail if the file path to some files is too long. If the build fails, please try cloning ArduPilot into a directory very high in the directory structure (i.e. ~/ardupilot).
If during build process you get error of missing packet xyz, re-check that you have installed all cygwin packets listed above
