Firmware build fails after forking and integrating sitl_gazebo fork

1

Hi All,
I’ve made a fork of px4 Firmware repository and sitl_gazebo repository. I’ve repointed the sitl_gazebo in Firmware respository to my fork. When I try to build after this change I get an error. I’d like to know how to do this correctly to avoid the error.

$make px4_sitl gazebo_xe4t

This problem usually occurs when the locale on your system is not set correctly.

What does locale output?

Hello @JulianOes
Here’s the output:
LANG=en_IN
LANGUAGE=en_IN:en
LC_CTYPE=“en_IN”
LC_NUMERIC=“en_IN”
LC_TIME=“en_IN”
LC_COLLATE=“en_IN”
LC_MONETARY=“en_IN”
LC_MESSAGES=“en_IN”
LC_PAPER=“en_IN”
LC_NAME=“en_IN”
LC_ADDRESS=“en_IN”
LC_TELEPHONE=“en_IN”
LC_MEASUREMENT=“en_IN”
LC_IDENTIFICATION=“en_IN”
LC_ALL=

Aha, the other thing could be that you don’t have the version tags. Make sure to do a git fetch and check that all tags are available if you do git tag or check git log.

Hi @JulianOes git fetch solved the issue.

Thanks,
