ARM device compilation

[pereira90-ai]

Hi, Jiarong.

I hope you are doing well.

During the installation I got this issue:
C++: error: unrecogniaed command line option: '-msse2'

I think this issue is caused because of the difference between device architecture. (I'm using Jetson Orin whose arch is arm64)
I found those optimization options are not supported on ARM64 device.

And then what should I do? Just eliminating them or should I add new options?

Thanks for your consideration.
Best,

I removed the two options "-msse2" and "-msse3" in CMakeLists.txt, then this error you have encounted was disappeared:
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -std=c++14 -O3 -lboost_system -pthread -Wenum-compare -DWITH_GTK_2_X=ON")
This sentence is in CMakeLists.txt line 6.

Hi @shallwing
Thanks for your help.
After removing those options I encountered new issue related to 'cpuid.h'

And currently ROS uses opencv 4.5.4 but I think 4.5.3 is supported.
How can I downgrade this opencv version into 4.5.3?
Thanks.

The author has declaimed in this URL that now we can only run the project in x86... what a pity!
