Pylada-light installation error

[nhjkjh0608]

Hi I am trying to install pylada-light

When I entered pip3 install git+https://github.com/pylada/pylada-light --user,
an error appeared below.

May I ask you solution for this error??

My python version: 3.6.6
cmake version: 3.16.2

I also tried with python2.7 and an error still appeared

[mdavezac]

Could you check the compiler supports C++11?

[ftherrien]

I have been having the same issue when installing pylada on clusters that have somewhat old versions of the compilers. I think @mdavezac is right, forcing the c++11 standard solves the issue for me:

CXXFLAGS="-std=c++11" pip3 install git+https://github.com/pylada/pylada-light --user

@mdavezac should we add this to the c++ flags in setup.py? (I don't know much about cmake so I am not sure where exactly)

[mdavezac]

I'm not too keen on adding hard-coded flags. They might make other setup fail.
I think the issue might actually be the version of CMake. There's a branch where I'm trying to clean this up, but it's not quite ready yet.
