features.h not found #521

Closed chavid closed 3 months ago

chavid commented 3 months ago

Hello. I'm trying again to build a docker recipe for a jupyter lab image with xeus-cling. I can't get rid of a "features.h not found" error when I run any C++17 notebook. My latest simplified recipe attempt below. Any idea welcome.

FROM quay.io/condaforge/miniforge3
RUN mamba install -y jupyterlab
RUN mamba install -y xeus-cling
ENTRYPOINT [ "jupyter", "lab", "--port=8888", "--ip=0.0.0.0", "--no-browser","--allow-root"]

Just as a data point: this (big) environment worked smoothly last time I installed it (about one month ago):

The difference could be in:

It would be preferable indeed if the simplified recipe above worked at once.

Which docker image you started from ? I have the same symptoms with either quay.io/condaforge/mambaforge or continuumio/miniconda3, whatever the version. The difference is maybe in the fact to install within a dedicated environment or not.

After dozens of failures, I got it to work starting from a fresh miniconda python311 installation. That was a fight, especially because I was also needing the classical notebooks and old-style rise activated (I dislike default code extracts font sizes with the new jupyterlab_rise).

In docker: mambaorg/micromamba:latest. Also on my machine with a mambaforge install.

Have you tried jupyterlab-deck? I find it more robust and less interfering with JupyterLab's user interface (style, ...). Just don't use subslides for now. (sorry for derailing in this thread).
