unable to install Linorobot - YDLidar SDK missing folder

[Rossobimbo]

HI Grassjelly,

when running "install_linorobot_2.bash" i get the following error

install_linorobot2.bash: line 62: cd: YDLidar-SDK/build: No such file or directory

i've also modified line 18 from ROSDISTRO="$(rosversion -d)" to ROSDISTRO="$(echo $ROS_DISTRO)" as otherwise it wouldn't recognize the distro version.

I've checked on YDLidar github, and the "build" folder is not longer there.

Any suggestion?

you found a bug! fixed it with this https://github.com/linorobot/linorobot2/commit/7a64f529dcd30f95e8c4c32dc32b665067fc85a3

thanks for fixing that, although now i get the following: CMake Error: The source directory "/" does not appear to contain CMakeLists.txt

Hi there,

i copied the cmakelists.txt from the YDlidar github into the / folder of the robot PC. Unfortunately i'm still getting the following error: The C compiler identification is GNU 9.3.0 -- The CXX compiler identification is unknown -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Detecting C compile features -- Detecting C compile features - done CMake Error at //CMakeLists.txt:2 (project): No CMAKE_CXX_COMPILER could be found.

Tell CMake where to find the compiler by setting either the environment variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path to the compiler, or to the compiler name if it is in the PATH.

Any ideas?!? Thanks

for anybody else which might have the same problem, i solved it by running: sudo apt install build-essential

My current configuration is Ubuntu Server 20.04.3 LTS on a Raspberry Pi 4
