catkin_make error

[boeun98]

I downloaded and did catkin_make on Jetson Xavier.

but, i had an error like that.

and I can't install nmea_msgs via sudo apt-get instsall ros-melodic-nmea-msgs
It's has an error (E: Unable to locate package ros-melodic-nmea-msgs)

How can I install nmea_msgs?

What branch did you download? The ros2 branch isn't going to work with ROS Melodic, but the master branch should.

[boeun98]

I downloaded via 'git clone https://github.com/ros-drivers/nmea_msgs.git'

How can I download for ROS melodic?

Change to the branch ROS 1 branch with

git checkout master

[boeun98]

I used that command
git checkout master

but, I have an error.
fatal: not a git repository (or any of the parent directories): .git
