when compiling project with Ubuntu 16.04, CUDA 9.0 and NVIDIA drivers 396.54, I encounter problems:

thanks a lot.

having the same issue. Initially thought it was a conflict between Eigen and cuda version. Tried with Eigen 3.2 and 3.3 with Cuda8, still did not work.

Any idea?

[mp3guy]

Use the version of Eigen included in the third-party folder.

[threedlife]

thanks mate @mp3guy. I actually did tried with the Eigen included in the third party folder (seems to be v3.3.90) checked out by git submodule update --init But it reported same errors.

I am using ubuntu 16.04, CUDA 8.0, btw. Any further thoughts?

[mp3guy]

Only Ubuntu 18.04 with CUDA 10 is supported since ac9220f.

[aditya2592]

@threedlife Were you able to get it running with Cuda 8 and 16.04?

I also met this before, so I tried to reimplement to make it easy to compile and use.
Here is the codes. Hope it helps.

@duanyongli @threedlife @aditya2592 It is a simple error caused by the low version of c++ during compiling. Please add -std=c++11 at CmakeList.txt.
Change
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS} "-Xcompiler;-fPIC;--expt-relaxed-constexpr")
to
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS} "-Xcompiler;-fPIC;--expt-relaxed-constexpr;-std=c++11")

Hope it helps.
