Mavros: Geographiclib target directory not found

sudo apt-get install libgeographic-dev
sudo apt-get install geographiclib-tools

And then run the script again.

A note:

I'm using 3DR Solo with the initial setup. So I guess it's PX4 based (am I right?) with APM on it.

3DR Solo flight controller is Pixhawk 2.1 (Cube). PX4 and APM are fligh stacks that may run on it.

sudo apt-get install libgeographic-dev
sudo apt-get install geographiclib-tools

Thank you for your help!
I tried it and successfully installed geographiclib-tools,
but it says it cannot find libgeographic-dev.

3DR Solo flight controller is Pixhawk 2.1 (Cube). PX4 and APM are fligh stacks that may run on it.

I am assuming that Hardware is Pixhawk 2.1 and the software is PX4 or APM.
However, for software, I have read that to upload a firmware,
I need to git clone

https://github.com/3drobotics/ardupilot-solo
https://github.com/3drobotics/PX4Firmware-solo
https://github.com/3drobotics/PX4NuttX

and eventually make all of these.

Sorry. Saw now you are with 14.04. Then issue sudo apt-get install libgeographiclib-dev.

Thank you TSC21.
sudo apt-get install libgeographiclib-dev did work.
However, it still cannot install geographic datasets.

Geographiclib target directory /usr/share/geographiclib not found

do you have any idea?
sorry for asking too many quesitons

I can't really tell. Considering you already install GeographicLib and the tools for downloading the datasets, it should work with geographiclib-datasets-download egm96_5. I can't test it myself as I'm using Ubuntu 16.04, but the above scripts should have installed the required libs and files. What's the output of locate geographiclib or locate GeographicLib?

A bit off: Solo uses Pixhawk 2, not 2.1 (that is made by hex, cube+carrier). And as i know, 3DR cube a bit different from cube made by hex, but mostly compatible.
By default Solo use APM firmware (also special version, but i think that vanilla should work too).

Try just create that directory sudo mkdir -p /usr/share/geographiclib, also check where libgeographic.so is located.

I tried sudo mkdir -p /usr/share/geographiclib and ./src/mavros/mavros/scripts/install_geographiclib_datasets.sh
It did start to download the geographiclib datasets.

Then I followed the further instructions written in README.md and tried to roslaunch.
It said it could not find anything in /usr/share/geographiclib/GeographicLib/,
so I sudo mkdir GeographicLib and mv geoids/ GeographicLib/, and it worked.

By the way,
I could successfully connect to 3DR Solo with
roslaunch mavros apm.launch fcu_url:=udp://:[email protected]
for those who want to develop with 3DR Solo!

Thank you so much for your help @TSC21 and @vooon
