Hello,

This folder is generated on compilation time from the mavlink submodule

magicrub commented 6 years ago

can you show your compile output? This gets generated at compile time so it's probably failing in there somewhere but somehow still trying to continue and failing elsewhere

Actually it seems something is going wrong. I am using a VM machine with Ubuntu Kinetic.

I followed these steps: git clone https://github.com/ArduPilot/ardupilot.git Run the install-prereqs-ubuntu.sh script by running this command ./ardupilot/Tools/scripts/install-prereqs-ubuntu.sh

Then I installed the following packages

cd

sudo add-apt-repository ppa:george-edison55/cmake-3.x -y
sudo apt-get update
sudo apt-get install cmake

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-4.9

sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo apt-get update
sudo apt-get install gcc-arm-none-eabi=4.9.3.2015q3-1trusty1

sudo apt-get update
sudo apt-get upgrade

I had an issue with sudo apt-get install gcc-arm-none-eabi=4.9.3.2015q3-1trusty1

so I run the following instead sudo apt-get install gcc-arm-none-eabi without version and it seems to work.

Then I run ./waf list_boards then: ./waf configure --board px4-v2

Here I had an issue, I got the following error

riotu@ubuntu:~/ardupilot$ ./waf configure --board px4-v2

so, I tried another board navio2 ./waf configure --board navio2 I got a different error

(complete log in /home/riotu/ardupilot/build/config.log)

I am not sure what would be the error.

I run the configure without any board as riotu@ubuntu:~/ardupilot$ ./waf configure

and there were no errors

Then I compiled as:

Build commands will be stored in build/sitl/compile_commands.json
'copter' finished successfully (2.004s)

and it showed a success

but in the folder libraries/GCS_Mavlink, there are no folders created after compilation as it would be expected.

I do not know if I missed any step or there is something wrong to make it work Any help will be appreciated.

Thanks

We try to don't do support on the issue list, there is nothing wrong here. You will find the mavlink folder in build/sitl/libraries/GCS_MAVLink/include . I closing now, please open a topic on if you need more help : http://discuss.ardupilot.org/ Other points : gcc-arm-none-eabi isn't the same as our toolchain. on px4-v2 error, try git submodule update --init --recursive on navio2, you don't have arm-linux-gnueabihf compiler
