Can not build PX4 firmware on ubuntu

1

Hi,

I have followed the steps as mentioned here: https://dev.px4.io/en/setup/dev_env_linux_ubuntu.html

I get this output:
root@px4test-ubuntu:/home/oaasadmin/src/Firmware# arm-none-eabi-gcc --version

I got the source and trying to build px4 firmware using the cmd: make px4fmu-v2_default

failed with the following error:

As you can see, arm-gcc is available in the system but getting gcc not found. Can you please help me here?

Are you sure you have gcc installed? Running “gcc -v” at the command line should tell you if you do and what version you have (mine is v5.4, it works).

Thank you for quick response. bin path seems to be not set properly. After setting the path, I can verify gcc version.

And then, I ran the same cmd: make px4fmu-v2_default

it is failing at this point

do you think any other bin paths are missing from $path variable?
