Building Pixhawk with Make on Windows

[Randy Mackay]

Jefferson,

 

     I can’t help with building for px4/pixhawk on Linux but I can help re windows.

 

     Can you follow these instructions and report back on the specific place where it fails?

I am having the same problem and I have installed the toolchain with the script file and then redid it with the instructions you posted as well as the instructions on ardupilot's website. I haven't had success in compiling the ardupilot for pixhawk in windows with make or eclipse with multiple different methods used. I looked at the instructions for setting it up in linux and it seemed simple so I tried it and nothing seems to work right. Is there something I keep missing in all of this?

(so far all the problems have been with the submodules: UAVCAN, NUTTX, Px4Firmware. haven't had a problem compiling the actual ardupilot code for APM2 in linux or windows)

also, I entered this into the terminal:
arm-none-eabi-gcc
and it did recognized it. It popped up an error because no file was specified to compile, but the command is there. Why can't make see the command?

Okay, so this morning, I uninstalled everything I had done, deleted all my repositories, and started from scratch. somehow it did compile this time. I'm not sure where the difference was. The only thing I did differently was I used the "Clone in Desktop" Button on Github instead of cloning it by CLI with the github shell.

It compiled but at the end popped up two (I'm assuming non-critical) errors. here is the end of the output from the compiler:

Success! That error is normal. What you're looking for is that the firmware .px4 file was generated.

Okay so I'll just ignore that error.  Maybe we can mention that on the list of common errors on the wiki on the page here so others don't have to wonder.

I am now trying to compile the 3.2.1 code and keep getting a python import error. Any ideas there?

It can't find the genmsg.template_tools module. It says install empy and catkin_pkg but they already are installed.

I've had this issue many times now and started from scratch a few times but it always pops up. 

[Jefferson Romney]

Well now that I have successfully built v 3.3, I am trying to build 3.2.1 and having trouble. I first got an error with the gencpp and genmsg. I found those online and installed them. Then I found them in the mk/PX4/Tools directory also. Now I get the error right at the end of the build that 

make[1]: *** No rule to make target `px4fmu-v2_APM'.  Stop.

Is this also a build environment problem?

the same problem. Does it matter?

Build using make, not "Eclipse".

[Wang Eric]

Then how to debug?

Depends on what you're wanting to test. SITL works fine for most things and you don't compile in eclipse for that either.

[Chuk Rhodes]

These changes in ardupilot/mk/px4_targets.mk will fix the errors at the end of the compile.

And I have it working in Eclipse. It took a few tries, but it seems if you follow the directions and get a successful build in "px4 console", then launch "px4 eclipse", it works fine. You do have to use the Make Target window, where it shows "px4-v2", etc. I'm also using Eclipse Mars, just modified the toolchain/msys/1.0/px4_eclipse.bat to point to the new version.
