Getting Error while installing rtabmap_ros

[AyanHBK123]

I am following your guide from:
http://eleccelerator.com/wiki/index.php?title=Raspbian_Buster_ROS_RealSense
and I am now installing rtabmap_ros but I am getting these error,

when I run the command
catkin_make -j1
I get this error

CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkin_workspace.cmake:100 (message):
This workspace contains non-catkin packages in it, and catkin cannot build
a non-homogeneous workspace without isolation. Try the
'catkin_make_isolated' command instead.
Call Stack (most recent call first):
CMakeLists.txt:69 (catkin_workspace)

make: *** [Makefile:1526: cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" failed

after getting this error I run the command
catkin_make_isolated
as mentioned in the error
but this leads to this error

anyway to solve this problem ??

[frank26080115]

I can only guess, but maybe try running

sudo apt-get install libeigen3-dev

If the eigen_conversions part is failing to build, maybe eigen3 or something eigen3 depends on isn't installed, so running apt-get on libeigen3-dev should install what is missing

Hope that works

[AyanHBK123]

Its latest version is already installed.

[frank26080115]

hmmm maybe figure out how to install the expected version of KDL?

https://orocos.org/wiki/Installation_Manual.html

[AyanHBK123]

well that worked for me using the link but I am getting this error:

so this is a new error I am getting now:

I did some searching, maybe this will help

https://answers.ros.org/question/231666/catkin_make_isolated-does-not-create-envsh/

check if test_tf2 is indeed a catkin package, if it is not, apply the fix as suggested in the link I just posted

[AyanHBK123]

Thank you very much I have successfully installed rtabmap_ros, now I am on my last that is PCL 1.7.
You have given how to solve the issue but an official guide install it is not given i have searched the web and now doing it from this link:
https://answers.ros.org/question/229788/how-to-building-pcl-laser_scan_matcher-on-raspberry-pi-2/

but this is for pi 2 ,
any suggestion regrading this ??

I following this guide but I keep getting this error:

i get this error when i do it with make command:

I am using Pi 4 8 GB ram but 32 GB SD card.
I have already swap the ram to 2048 size and expanded file system .

[frank26080115]

Try -j1 for single threaded build, also maybe keep adding swap until you have enough
