How to build python binding in an Anaconda environment? #2

Closed xueeinstein closed 3 years ago

xueeinstein commented 3 years ago

I am trying to use Ripser++ in an anaconda environment. All the test cases passed after built the C++ version. However, when I install the using source install_w_python_bindings.sh, it raised errors like:

.../x86_64-conda_cos6-linux-gnu/include/c++/7.3.0/type_traits(2953): error: "constexpr" is not valid here
...
...error: "is_pod_v" is not a function or static data member

Could you please take a look? To be sure that it is not a common problem, I cannot find similar issues on Stackoverflow :(.

Hi Bill,

My guess is your versions of gcc and nvcc are off. I think I use gcc version ==8.4.0 and nvcc version ==10.1. In case you just need to run ripser++, I have a gist in another issue on how to use ripser++ in Google Colab (which runs on cloud instead of on your local machine).

Thanks, Simon Zhang

Hi Simon,

Thanks for your help! My nvcc version is 10.0. I happened to find that gcc 4.8.2 works for me. While gcc 7.3.0 seems not compatible with nvcc 10.0.
