C++ 17 Kernel doesn't work with Jupyter Console #415

Waerden001 · 2021-08-23T05:20:00Z

Install xeus-cling in a clean conda enviroment xcpp11 and xcpp14 works fine with jupyter console, however xcpp17 doesn't work.
To reproduce the issue

conda create -n cling
conda install jupyter 
conda install -c conda-forge xeus-cling

Then run jupyter console with xeus-cling kernels

jupyter console --kernel xcpp11

and

jupyter console --kernel xcpp14

work as expected. However

jupyter console --kernel xcpp17

gives error information

Traceback (most recent call last):

I wonder if there's any way to fix this?

Me too! C++17 fails on Mac Catalina after clean install of JupyterLab and Xeus-cling, when opening a notebook that was developed under xeus-cling C++17 and worked perfectly before. The error messages are different from above:

I installed xeus-cling as described by @Waerden001 above under Ubuntu Linux 20.4. I am facing the same issues except that

jupyter console --kernel xcpp17

just hangs forever. No error messages.

FrCln · 2021-10-20T08:06:43Z

I encountered the same problem on Manjaro Linux. Solved by installing older version of xeus-cling:

conda install xeus-cling==0.9.0 -c conda-forge

This version works with C++17 fine.

dimitry-ishenko · 2021-10-22T02:20:51Z

In my case the console does start, but fails as follows:

NB: I've built a Debian package for xeus-cling, which is accessible here.

mert-kurttutan · 2021-11-17T00:11:14Z

The same type of problem occurs here. First, I installed jupyter before installing xeus in my conda environment. Then, I installed xeus in this environment. It is all fine except for c++ 17 Kernel. It just keeps restarting until the fifth time, then it fails. My OS is pop-os 20.04.

idati · 2021-11-24T17:52:39Z

same issue with wsl ubuntu + jupyter notebook
(on windows installation its fine)

pedrior · 2022-08-05T20:59:32Z

As mentioned above, installing older version of xeus-cling (to 0.9) seems to solve the problem.

dimitry-ishenko · 2022-08-07T14:58:39Z

@petyrj that's not really a solution, but rather a workaround.

rubdos · 2022-08-25T12:36:34Z

Anyone coming around where this happened the last ~1 month: pin the stdcxx library.

conda install xeus-cling \
    libstdcxx-devel_linux-64==9.4.0 \
    libgcc-devel_linux-64==9.4.0 \
    -c conda-forge

Symptom was:

Warning in cling::IncrementalParser::CheckABICompatibility():
  Possible C++ standard library mismatch, compiled with __GLIBCXX__ '20210601'
  Extraction of runtime standard library version was: '20220527'

and the automatically installed version from conda was 9.5.0. C++11 seemed to work, but C++14 and C++17 were broken.

mariop64 · 2022-09-22T01:55:18Z

Whew, glad to see I am not the only person dealing with this issue! Has there been any resolution or update?

dimitry-ishenko · 2022-09-23T14:24:22Z

@mariop64 it seems to be working for me now:

Although, I am not using Conda, but installed .deb packages from this PPA:

https://launchpad.net/~ppa-verse/+archive/ubuntu/xeus-cling
