Compilation error on Eigen3

Hi,

Thanks for the code! Sadly it fails to build with an Eigen static assertion error:

did you have solved it?

You should find libnvToolsExt.so and copy/link it to your library path. In my case, the shared library path is /usr/local/cuda-9.0/targets/aarch64-linux/lib/libnvToolsExt.so

Hi @yunchih , @Halcao . I had a similar error with eigen , here is the error log:

I tried with all the solutions in this issue it did not work any help how to solve this error. thank you in advance.

Did you follow this?

Did you follow this?

thank you for your reply. I found that Pangolin version was the problem I installed 0.5 version instead and it solved the problem.
