Cobalt 23.lts.1+ error

[kguru...@gmail.com]

Hi, 

I've been following the following instructions to build cobalt 23
https://cobalt.foo/development/setup-linux.html

when i run the following command on my ubuntu i get the following error

Command: python cobalt/build/gn.py -c gold -p android-arm

out/android-arm_gold/args.gn already exists. Running ninja will regenerate build files automatically.
gn gen out/android-arm_gold
Build Accelerator: ccache
ERROR at //starboard/tools/BUILD.gn:18:15: Script returned non-zero exit code.
  file_list = exec_script(script, [ "-l" ], "trim string")
              ^----------
Current dir: ~/cobalt/out/android-arm_gold/
Command: python ~/cobalt/starboard/tools/app_launcher_packager.py -l

i assume the starboard is installed as part of pre requirements step in the instructions.

Anyone faced this issue ?

Thanks.

You need to set the PYTHONPATH environment variable to point to the root of the cobalt repo. So say you cloned the repo to /somedir/cobalt, PYTHONPATH would be /somedir/cobalt.

Yup. i see my PYTHONPATH has an extra character. I tried to correct it and restarted the terminal and did source on bashrc. Problem resolved.

Hi,

I follow instructions to build Cobalt 24, from this link,

https://cobalt.googlesource.com/cobalt.git/+/refs/heads/24.lts.stable/cobalt/site/docs/development/setup-linux.md

and stuck with this below error,

~/src$ python3 cobalt/cobalt/build/gn.py -c debug -p android-arm64

Traceback (most recent call last):

  File "cobalt/cobalt/build/gn.py", line 25, in <module>
    from starboard.build.platforms import PLATFORMS
ModuleNotFoundError: No module named 'starboard.build'

when i run the following command on my ubuntu i get the following error

Command: python cobalt/cobalt/build/gn.py -c gold -p android-arm64

After setting the pythonpath and also did source on bashrc. Still facing the same issue?

Based on the paths you mention, I think you are one directory up from where you want to be.

E.g. instead of running "python3 cobalt/cobalt/build/gn.py" from ~/src, you should be running "python3 cobalt/build/gn.py" from ~/src/cobalt

Additionally, then your PYTHONPATH should be set to ~/src/cobalt
