error: do not know how to extract

[pioneerbkh]

gcc (Ubuntu 5.4.0-6ubuntu1~16.04.4) 5.4.0 20160609 cmake version 3.5.2 ninja version 0.1.3 The Compile message is...

I think this is an error from missing submodules.

Can you try running: git submodule update --init, and try compiling again?

Comment back what you find!

[pioneerbkh]

It's same as before

travis-byun@HCI:~/WorkSpace_vim/rrt/rrt-master$ git submodule update --init travis-byun@HCI:~/WorkSpace_vim/rrt/rrt-master$ make mkdir -p build cd build && cmake .. -DCMAKE_INSTALL_PREFIX:PATH="" -GNinja && ninja -- Found Qt5: /usr/lib/x86_64-linux-gnu/cmake/Qt5Widgets CMake Error at /usr/share/cmake-3.5/Modules/ExternalProject.cmake:964 (message): error: do not know how to extract '/home/travis-byun/WorkSpace_vim/rrt/rrt-master/third_party/googletest/googletest' -- known types are .7z, .tar, .tar.bz2, .tar.gz, .tar.xz, .tbz2, .tgz, .txz and .zip Call Stack (most recent call first): /usr/share/cmake-3.5/Modules/ExternalProject.cmake:1909 (_ep_write_extractfile_script) /usr/share/cmake-3.5/Modules/ExternalProject.cmake:2459 (_ep_add_download_command) cmake/SetupGTest.cmake:5 (ExternalProject_Add) CMakeLists.txt:96 (include)

[jgkamat]

Hmm, that is pretty weird. Can you try running this command:

git submodule sync && git submodule update --init

Also, if that dosen't work, could you post the output of: git status and git submodule

[jgkamat]

also I noticed your path is: ~/WorkSpace_vim/rrt/rrt-master

Can you cd up to the ~/WorkSpace_vim/rrt folder and try these commands again?

[pioneerbkh]

I got something different messages

[jgkamat]

Hmm, this is pretty weird. Can you try deleting the rrt folder and recloning it with git clone https://github.com/RoboJackets/rrt.git?

after you do that, cd inside the newly created rrt folder, run git submodule update --init and make

[jgkamat]

Also, can you ensure you have the ninja-build package installed:

sudo apt install ninja-build (You are on ubuntu 16.04, correct?)

[pioneerbkh]

That's right. I followed your solution but it's still unnatural. It's same as before. I can not form any idea of what it is.

[jgkamat]

Can you run the following commands, which should set up a new rrt repo properly configured in your /tmp folder?

sudo apt install ninja-build qt5-default libeigen3-dev cd /tmp git clone https://github.com/RoboJackets/rrt.git cd rrt git submodule sync git submodule update --init make make run

and report the output of any of these steps if it fails? (the output of all these steps would help if you're still haivng issues).

[jgkamat]

perfect, I think we almost have it set up! Can you try running sudo apt install ccache?

I think we need to add that to the README, we forgot about that. Once you have that installed, could you try running make run in /tmp/rrt and see if that fixes compiles?

[pioneerbkh]

Thanks a lot.

It works.

[jgkamat]

Thanks for trying this out! let us know if you run into any other issues :smile:
