Building The Code Problem

1

Hi, I am new to px4 and I am trying to follow the dev guide and build the firmware.

I managed to clone the upstream repository, however I am getting an error when executing the make command:
make px4fmu-v2_default

The error I receive:
$ make px4fmu-v2_default
/bin/sh: cmake: command not found
rm: cannot remove directory `/usr/home/Julian/src/Firmware/build_px4fmu-v2_default’: Permission denied
make: *** [px4fmu-v2_default] Error 1

I tried to run the PX4 as admin since it seems to be a problem with permission, but I still got the same error. I would appreciate any help, thank you

You should install cmake and configure environment variable.
After that you can execute “cmake --version” in DOS cmd or git bash.
If there is a cmake note,you can try to rebuild your code.

why you have “Permission denied”, permission problem ,first install cmake

I installed cmake but I am not sure how to configure environment variable. I apologise but I am still new to this.

Were you able to fix this issue? I’m getting the same error.

I have installed cmake (I thought it came with the px4 toolkit, but I guess not?).
I am running the PX4 Console as an administrator.
I tried running “make clean” but also get an error: make[1]: *** No rule to make target ‘clean’. Stop.
I have disabled .NET Framework 3.5 (includes .NET 2.0 and 3.0) per recommendation on another thread
I am using Windows 10.

I’ve got the same problem on Windows 7. I can confirm that the px4 console can find cmake.

8

it works if you build in bash
