Issue Description

I'm trying to install LibUVC on a raspberry pi 4, but when I try
./libuvc_installation.sh
I get to 66% of the process and get the error

[ 60%] Linking CXX shared library librealsense2-gl.so
[ 60%] Built target realsense2-gl
make: *** [Makefile:130: all] Error 2
pi@raspberrypi:~ $

I would love some help!
I have tried
sudo apt-get update && sudo apt-get upgrade && sudo apt-dist-upgrade -y

Are you using the script from libuvc_installation.md?

https://github.com/IntelRealSense/librealsense/blob/master/doc/libuvc_installation.md

@dorodnic I am using all the instructions there, do you have any other advice?
thanks.

I'm waiting to get my Rpi4 to try the installation on. First steps of the script set-up swap file, without which installation fails due to lack of memory. If this is not the reason, I suspect something to do with OpenGL and graphics drivers. For Ubuntu 18 we ask to run:
sudo apt-get install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev
Probably something similar needs to be done on the Pi.

I got it working.
Just add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -latomic") to the CMakeLists.txt file and compile.

[GOBish]

@AnupamYedida I really appreciate your help!
Could you walk through the steps for me a little more clearly? I apologize, I don't have a ton of experience with this. How do I get to the cmakelists.txt file?

[AnupamYedida]

It's in the librealsense-master directory. (Provided you ran the script)

[GOBish]

Hmm, I still get the same error at 60%.
[ 60%] Linking CXX shared library librealsense2-gl.so
[ 60%] Built target realsense2-gl
make: *** [Makefile:130: all] Error 2

@AnupamYedida are you using Raspbian Buster?

[GOBish]

I tried it again, making all the changes to cmake files as described here (by @SirDifferential):

#4375 (comment)

and still could not complete the compile, got this error at 58%

make[2]: *** [examples/software-device/CMakeFiles/rs-software-device.dir/build.make:63: examples/software-de/github.com//issues/4375#issuecomment-509968417vice/CMakeFiles/rs-software-device.dir/rs-software-device.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:511: examples/software-device/CMakeFiles/rs-software-device.dir/all] Error 2
make: *** [Makefile:130: all] Error 2

[AnupamYedida]

It's the CMakeLists.txt file in the folder librealsense

[GOBish]

Thanks @AnupamYedida -- I did that in #4950 (comment) and was still unsuccesful.
Where in the CMakeLists.txt file did you put that line of code?
Also, I just ran sudo apt-get install libatomic-ops-dev
and I am re-compiling to see if that addresses my issue.

[AnupamYedida]

I kept it in the top. It fixed the issue for me. I'm running it on 4.19 kernel, Raspberry Pi4, Debian Buster

[GOBish]

@AnupamYedida I don't know, I can't get it to work no matter what I try.

This is what worked for me. Your mileage may vary. 4.19 kernel, Raspberry Pi4, Debian Buster with Neural Computer Stick 2

First run:
sudo apt-get install libglfw3-dev libgl1-mesa-dev libglu1-mesa-dev

Per the LibUVC installation instructions
wget https://github.com/IntelRealSense/librealsense/raw/master/scripts/libuvc_installation.sh
chmod +x ./libuvc_installation.sh
./libuvc_installation.sh

It will error at:
[ 60%] Linking CXX shared library librealsense2-gl.so
[ 60%] Built target realsense2-gl

find the location of your librealsense_build directory:
pwd ~/librealsense_build

in my case it was /home/pi/librealsense_build

nano libuvc_installation.sh
or edit with whatever editor you like

In libuvc_installation.sh
change this:
sudo rm -rf ./librealsense_build
mkdir librealsense_build && cd librealsense_build

to this:
#sudo rm -rf ./librealsense_build
cd /home/pi/librealsense_build

*replace /home/pi/librealsense_build with your librealsense_build location

Find the CMakesLists.txt file in the librealsense-master directory
Add set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -latomic") to the top of the CMakeLists.txt file.

Run: sudo ./libuvc_installation.sh

@w3bm0nk3y I appreciate the help - but I still get the error at 60% in the compile even following the steps you outlined.
