Compilation fails with latest version of master

[Lubomír Bureš]

Hi,

When compiling the latest version of master, I am getting an error (see below). When using the tagged version (v19.0), things work well. Any idea?

Thanks,

Lubomir

Hello Lubomir,

This is an issue with the gslib not pulling properly. I would remove and replace the gslib folder in Nek500/3rd_party/. I would try that.

Thanks! What helped was to navigate to the `gslib` directory and run the `install` script there, since it has a `wget` in it.

Upgrading to a newer GCC fixed this for me, but the suggestions above did not work.
