1. Why do I need it?
|
|
--------------------
|
|
It allows to use the "Big Hammer", that is, to build whole OpenPilot system
|
|
with a single command "make all" using the top level Makefile originally
|
|
written for Linux and Mac only.
|
|
|
|
Also any routine task automation could use the same set of scripts and commands
|
|
on all platforms (Linux, Mac and Windows) if scripts are written in the shell
|
|
language. It is particularly important for cross-paltform projects like the
|
|
OpenPilot.
|
|
|
|
|
|
2. How to install?
|
|
------------------
|
|
Fortunately, it requires only few small text files since all others components
|
|
should already be installed on your system as parts of msysGit, QtSDK and
|
|
CodeSourcery G++ packages required to build the OpenPilot.
|
|
|
|
It is expected that you have the following tools installed into the listed
|
|
locations (but any other locations are fine as well):
|
|
|
|
- Python in C:\Python27
|
|
- QtSDK in C:\QtSDK (depending on SDK version)
|
|
- CodeSourcery G++ in %ProgramFiles%\CodeSourcery\Sourcery G++ Lite
|
|
- msysGit in %ProgramFiles%\Git
|
|
- Unicode NSIS in %ProgramFiles%\NSIS\Unicode
|
|
- OpenOCD in C:\OpenOCD\0.4.0\bin (optional)
|
|
|
|
The SDL library and headers should be installed into Qt directories to build
|
|
the GCS. Check the wiki or ground/openpilotgcs/copydata.pro for details.
|
|
|
|
Also it is assumed that you have the C:\Program Files\Git\cmd\ directory in
|
|
the PATH. Usually this is the case for msysGit installation if you have chosen
|
|
the 2nd option: put only git and gitk in the PATH (it is recommended option).
|
|
|
|
Now you need to copy few files to your msysGit installation folders.
|
|
Assuming that you installed the msysGit into C:\Program Files\Git\,
|
|
you have to copy:
|
|
|
|
make\winx86\bin\* -> C:\Program Files\Git\bin\
|
|
make\winx86\cmd\* -> C:\Program Files\Git\cmd\
|
|
|
|
If you have msysGit installed into another directory, you need to update paths
|
|
accordingly. Also if you have tools installed into different directories and
|
|
they are not in the PATH, then you may want to update paths in the sh.cmd
|
|
script too (it is self-documented).
|
|
|
|
Note for Windows 64-bit users: 64-bit systems use %ProgramFiles(x86)% folder
|
|
as default for program files instead of %ProgramFiles%. You have to check where
|
|
your tools are installed and update paths above accordingly.
|
|
|
|
|
|
3. How to use it?
|
|
-----------------
|
|
|
|
3.1. Interactive mode
|
|
---------------------
|
|
|
|
1) Type:
|
|
|
|
C:\> sh
|
|
|
|
and the bash prompt should appear:
|
|
|
|
user@pc /
|
|
$
|
|
|
|
2) Enter your OpenPilot directory:
|
|
|
|
user@pc /
|
|
$ cd D:/Work/OpenPilot/git
|
|
|
|
user@pc /d/Work/OpenPilot/git (master)
|
|
$
|
|
|
|
Note the current git branch in parentheses (master), if it exists. The path
|
|
format is also printed according to MSYS notation. And you have to use forward
|
|
slashes in paths, not backslashes.
|
|
|
|
3) Enter make command with required options and target list:
|
|
|
|
user@pc /d/Work/OpenPilot/git (master)
|
|
$ make all
|
|
|
|
The building should be started, and you will have full system including ground
|
|
software and flight firmware built in the end.
|
|
|
|
4) To build parts of the system you can use, for example, such commands:
|
|
|
|
user@pc /d/Work/OpenPilot/git (master)
|
|
$ make -j2 GCS_BUILD_CONF=release gcs coptercontrol
|
|
|
|
or to completely remove the build directory:
|
|
|
|
user@pc /d/Work/OpenPilot/git (master)
|
|
$ make all_clean
|
|
|
|
|
|
3.2. Batch mode
|
|
---------------
|
|
|
|
1) Create a shell script file containing all required commands, for instance:
|
|
|
|
#!/bin/sh
|
|
# This is the cc_make_release.sh file used to build CC release software
|
|
cd D:/Work/OpenPilot/git
|
|
make -j2 GCS_BUILD_CONF=release gcs coptercontrol
|
|
echo RC=$?
|
|
|
|
2) Run it typing:
|
|
|
|
C:\> sh cc_make_release.sh
|
|
|
|
3) Of course, a lot of other shell commands can be used in scripts.
|
|
|
|
|
|
4. Advanced usage
|
|
-----------------
|
|
|
|
It is possible to go further and integrate shell scripting into Windows system
|
|
like any other executables. This allows:
|
|
|
|
- double click on any .sh file in the Explorer window to execute it;
|
|
- type name of .sh file with any arguments on the command line to run script;
|
|
- omit .sh extension typing names since it is now recognized automatically;
|
|
- call .sh scripts even from .bat and .cmd files as Windows command;
|
|
- execute scripts which are in any directory in the PATH;
|
|
- return and check exit code from .sh scripts to .bat or .cmd batch files.
|
|
|
|
In short, you may have quite powerful and cross-platform bash scripting on
|
|
Windows.
|
|
|
|
In order to integrate bash scripting into Windows system you need to:
|
|
|
|
- double click on the included shell_script.reg file to register .sh
|
|
extension in the system. Thus, any click on .sh script will execute it
|
|
automatically assuming that the sh.cmd is in the PATH;
|
|
- register .sh extension as an executable file type, so you can omit the
|
|
.sh typing commands. To do so open "My Computer" properties dialog, choose
|
|
the "Advanced" tab, "Environment variables", in the "System variables"
|
|
find the variable called "PATHEXT". It contains the list of "executable"
|
|
file extensions separated by semicolon. You want to add a ";.SH" to the
|
|
end of its value. Then click OK to apply.
|
|
|
|
Now any .sh script can be run just by typing its name, optionally with
|
|
parameters.
|
|
|
|
As an example, you can create a shell script named make.sh in the cmd/
|
|
subdirectory of Git installation with the following content:
|
|
|
|
exec /bin/make $*
|
|
|
|
and then build the OpenPilot software typing
|
|
|
|
make all
|
|
|
|
directly from Windows command line or from a batch file.
|
|
|
|
You also may want to rename or remove "C:\Program Files\Git\etc\motd" file
|
|
to get rid of git bash welcome message on every script invocation.
|
|
|
|
|
|
5. Limitations of use
|
|
---------------------
|
|
|
|
Currently there may be some problems running scripts which contain spaces in
|
|
file names or located in directories which contain spaces in full paths.
|
|
It results in strange "file not found" or other errors.
|
|
|
|
It is recommended to avoid using such names with spaces.
|
|
|

distribution and MinGW make included into the QtSDK package.
