From the px4/Firmware directory, I have run
cmake .
Then, I try to run make eagle_default followed by make eagle_default upload. However, the eagle_default target is not available. I have previously cloned the PX4/Firmware repository and have run
git submodule update --init --recursive
Why is this target not available?
What branch of px4/Firmware are you using? Can you provide the error text when you run cmake?
I am on the master branch. My remote is:
origin https://github.com/PX4/Firmware.git (fetch)
origin https://github.com/PX4/Firmware.git (push)
Output from running cmake . from Firmware directory:
-- nuttx-px4fmu-v2-default
-- Using C++03
-- Release build type: RelWithDebInfo
-- Adding UAVCAN STM32 platform driver
-- Configuring done
-- Generating done
-- Build files have been written to: blablabla/px4/Firmware
As you can see, there is no error generated.
I then attempt to run make eagle_default, for example from the Firmware directory.
I have made an extra target in my Makefile to list all of the available targets in alphabetical order. http://stackoverflow.com/questions/4219255/how-do-you-get-the-list-of-targets-in-a-makefile . Here is the output of make list. The output is pretty long. There is no eagle_default target, as well as many of the other standard make targets that are suggested through the tutorials on dev.px4.io.

It looks like you have the wrong idea to me. Those “targets” are all the modules, libraries, drivers, etc. (basically features) which get built by cmake, compiled from all the CMakeLists.txt files in firmware/src/. Those aren’t the build targets you are looking for.
What you mean by “targets” I think are actually cmake config files, and are found in firmware/cmake/configs/
There is a separate cmake file for each “target” (config). The eagle configs are located there with the rest
The proper way to build eagle_default would be to execute in the root firmware directory $make eagle_default or, if you are using posix, specifically, $make posix_eagle_default.
Look at the MakeFile, starting at line 146, and you will see where make will call the correct cmake config.
I don’t think that the targets listed are compiled. CMake should generate a Makefile after I run cmake ., which lists all of the above targets as available targets for compilation. Those targets are the targets that are defined in the generated Makefile.
CMake should be able to generate a Makefile that works on all platforms for cross-compilation, so long as the Toolchain file is well-defined. So the call to make target should not be different for POSIX or Windows. Perhaps it is in this case.
I have, from the Firmware/ directory, attempted to run make eagle_default. I attempt to run cmake . to generate a new Makefile, but this does not generate a Makefile with the correct targets as defined on dev.px4.io.
My problem was that I ran cmake . from the Firmware/ directory before attempting to run make target. This generated a new Makefile in the Firmware/ directory with available targets defined in some CMake file or another. I’m not sure how that works actually. How can I run cmake to generate an updated Makefile if I need to?
The MakeFile already exists for all the configs / targets and you can see it in the repository.
I don’t know why you would need to generate a new Makefile using cmake. It doesn’t seem like the toolchain is set up to work that way.
EDIT:
If you called $cmake . in the firmware directory, then you would have overwritten the Makefile from the github repository (the one that has the correct targets defined).
Try this
$git checkout origin/<your firmware version> Makefile $make <target>
That will get you the correct Makefile and then you can try to build the target again.
The documentation for Building the Code might help you.
Ok, thank you. How can I add programs to the build process so that I may push them to my board?
I highly recommend you read through the Developer Documentation if you plan to develop software for the PX4 flight stack.
In particular, there is this section on Writing an Application that will introduce you creating your own programs and processes.
Also I recommend you familiarize yourself with the various example projects which already exist in the source.
Once you have created your programs, you will have to determine how to add them to the target config, and how to execute them. As far as I understand, this is platform dependent. I have only developed for px4fmu+nuttx, so I can’t help you there.
Good luck!
