Hello Vaishnavikumara,

It looks very likely that this is a duplicate of issue 380. The fix reported there is to add:

set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic")

...to CMakelists.txt.

best regards,

@scotthea-amazon I tried the fix you gave here. It still did not work. I am using rpi4 with debian 10.

@Chiggy-Playz me too

@Chiggy-Playz me too

you can solve the issue by going to the avs-sdk.../CMakeTextList.txt and then paste
set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic")

done for the atomic base error.

How do you get to this line? thanks

Same problem, I have added this line set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic") at the end of the file /librealsense/CMakeList.txt, but after installing the binaries, the issue persists:
undefined reference to '__atomic_fetch_add_8'
undefined reference to '__atomic_store_8'
undefined reference to '__atomic_load_8'

[coriolan-v]

I finally got it working by intsallint gcc 5 and trying again!
sudo apt-get install gcc-5 g++-5

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-5 60 --slave /usr/bin/g++ g++ /usr/bin/g++-5

sudo update-alternatives --set gcc "/usr/bin/gcc-5"

[Chiggy-Playz]

@coriolan-cs you edited the wrong file. you had to edit the file in source/avs-sdk-device/CMakeTextList.txt and then add the file in the end @angus390 follow the same

[coriolan-v]

Oh sorry about the confusion, I had this problem when building for Intel Realsense, not Alexa (I google the problem and arrived here)
Although I replaced source/avs-sdk-device/ by /librealsense/

[djcors]

i got a same error.

I try with
set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic")

at end of ~/avs-device-sdk/CMakeLists.txt

But not works for me

[Chiggy-Playz]

@djcors try putting it on the 9th line. That is just after the endif()

[kclchan]

This issue is fixed in v1.15 of the SDK.

[buddywhitman]

I have the latest SDK version but still faced the same issue.

[lombardian]

Yeeeehaaaa! It works. For newbies like me, you have to:

cd avs-device-sdk

then:

nano CMakeLists.txt

go to the bottom and add in the file:

set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic")

[cwchawt200]

sudo update-alternatives --set gcc "/usr/bin/gcc-5"

https://solarianprogrammer.com/2017/12/08/raspberry-pi-raspbian-install-gcc-compile-cpp-17-programs/

for Raspian 10 or above

[dusmit]

maybe you need use target_link_libraries(target atomic)
