You may want to do

git update-index --add --chmod=+x io/travis/build-wheels.sh
git commit -m 'Make build-wheels.sh executable'
git push

weird, the scipt appears to be python3 only

[SylvainCorlay]

Now we just need to install scikit-build in the docker.

[SylvainCorlay]

Maybe a requirement-dev.txt listing skibuild would work. I don't know the minimal version of Python that supports it but all the python3 versions that we support have it.

[JohanMabille]

It's already in it, I don't understand why it does not install skbuild when I install cmake first.

[SylvainCorlay]

It does not seem that the nlohmann_json package provides a nlohmann_json target unfortunately, but a nlohmann::json one instead.

[JohanMabille]

I think it does provide a nlohmann_json target, see its CMakeLists.txt. The find_package is not wrapped in the xtl, so the issue might come from here.

[SylvainCorlay]

Ah, ok, I thought that it was an alias problem.

[SylvainCorlay]

Is our vendored openssl installed at all with scikit-build?

[SylvainCorlay]

Note: trying to build locally. I am seeing

make[4]: Leaving directory '/home/sylvain/dev/jupyter-xeus/xeus-python-wheel/_skbuild/linux-x86_64-3.7/cmake-build/libuuid-download/libuuid-src'
 /bin/mkdir -p '/usr/share/bash-completion/completions'
 /usr/bin/install -c -m 644 bash-completion/uuidgen '/usr/share/bash-completion/completions'
/usr/bin/install: cannot remove '/usr/share/bash-completion/completions/uuidgen': Permission denied

[JohanMabille]

That is weird, I've never seen that locally. And the OpenSSL libraries are correctly installed (locally).

[SylvainCorlay]

so we are missing a setup.py dependency to jedi?

[JohanMabille]

and pygments. I'm adding them.
