Hi @Parvez

I understand that you are facing the issue while building firmware in px4 autopilot. The cause of the build failed error is most likely a permission issue. Launch MATLAB with "Run in Administrator" and try building the hardware setup.

Thanks,

Hello Ayush,

Thanks for your reply. I have tried it by running Matlab as Administrator but it is showing same error.

I am attaching error screenshots. If you have any idea related to its solution please reply.

Hi @ramzan

It seems like you are using PX4 Firmware of the Cygwin toolchain. Could you perform the following steps and tell me the output:

1. Launch the Cygwin console: Double click on "run-console.bat" in "C:/PX4".
2. In the Cygwin console type the command "cd /cygdrive/c/PX4/mypx4/Firmware" and enter.
3. Run the command "make px4_fmu-v3_default"

Hello @Ayush,

Thanks for your reply, as per your suggestion i have tried the commands in run_console.bat. it asking me to install packging by command 'pip3 install --user packaging'. I have tried this command but getting some error, i am attaching screenshots for your reference.

Hi @ramzan

As the command 3 did not work through Cygwin console, it indicates issue is with the PX4 Firmware on your machine. It seems like installation of PX4 Firmware of the Cygwin toolchain is corrupted. The best way to resolve this issue is to uninstall Cygwin Toolchain and clone PX4 Firmware again. Below are the steps:

1. Uninstall PX4 Cygwin Toolchain from Programs & Features in Windows
2. Clone and install Cygwin Toolchain again and clone PX4 firmware as mentioned here
3. Try building Firmware as mentioned above

Thanks,

Ayush
