Open Pulsar2011 opened 2 years ago

Hi, I started the docker following your instruction. I clicked either on C++ 11, 14 or 17 to start C++ session. I started with few simple line of code :

include

std::cout<<"test"<<std::endl;

And when I click the arrow ... nothing happen. The notebook hang waiting for the kernel to start. Bellow are the message from Jupiter log:

What did I do wrong ?

I don't think you have done anything wrong.

I have seen this issue before and it is when the upstream has done an upgrade.

I will run some tests and see what I can find.

I have spent some time on this and it is an upstream issue.

The kernels are not being installed now. I need to find a version that works.
