Hey, gcc 10.1.0 is released recently. Does anyone try to build vtk with gcc 10? I got something error like this:

```nohighlight

```

It seems that `vtk/Remote/PoissonReconstruction/Geometry.h` did not include `cstdio`. I didn’t get this error when I use gcc 9, not sure why.

The remote modules are not VTK code exactly. Upstream for it is at [https://github.com/lorensen/PoissonReconstruction](https://github.com/lorensen/PoissonReconstruction). Though since Bill is no longer with us, I think we may need a new home for this. @amaclean Do you have rights to that repo? If not, we’ll need someone to take up its cause.

I probably don’t. There has been very little activity on it since around 2011. It was forked from David Doria’s repository of the same name.

Oh, it’s a remote module. I think I could disable it.

Disabling it would be the best approach.

Not sure if the maintainer has disabled the module but we have it building in CI on Fedora, but have not done an official build yet.

Koji doesn’t allow network access, so I imagine that’s likely the cause there.
