building Issue

[RichardBaoRepo]

I run into problems while exexuting ./install.sh
the default installed protobuf version seems to be 25.3 and the lib version was 3.6.1,
so i tried to manually build protobuf 3.6.x from source, then everything look fine

then i tried
make -j8, i kept getting this error

error: #error "C++ versions less than C++14 are not supported." 79 | #error "C++ versions less than C++14 are not supported." | ^~~~~

I tried add the following lines in root CMakeLists.txt,

Set C++ standard for host code
set(CMAKE_CXX_STANDARD 14)

Set C++14 for CUDA code
set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -std=c++14")

still got no luck making it work, any help

i am working on UBuntu 20.04 with Nvidia 4090

For installing the Repo I can help you live, I have done the installation multiple times, but You should have the video in acceptable format to run the script successfully + It would be better if you use ubuntu 22.04 due to drivers availability.
