Updated from 4.6 to 4.7 and now KNIME is hanging on startup

image
I get this text and the KNIME splash popup which disappears after a while, but no extensions load and the nothing seems to happen for a over 30 mins. Is this part of the installation process or is it just hanging?

After installing a fresh version of 4.7.0 I’m still getting a hang on running with this log output:

In the mean time I reinstalled 4.6.4 and it runs fine. A shame I wanted to try the new features, but 4.7.0 is simply not running for me atm.

Having the same problem. Startup splash freeze.

Complete delete and reinstall.
Now OK.

Hi @Chimed

on which Linux distribution are you? Is it eventually Red Hat 7?

Best, Martyna

Hi @Martyna,

Yes, it’s a Centos 7 distribution.

Thanks,
Chimed

Hi @Chimed

unfortunately, they don’t ship the library that KNIME needs.
What you could try is to install the library that’s missing:

/lib64/libstdc++.so.6: version `GLIBCXX_3.4.20’ not found

Sorry for the trouble!

Best,
Martyna

Hi Martyna,

Thanks that put me on the right track and the problem was solved by loading a GCCcore/8.2.0 module. I’m now able to open 4.7.0 at last.

Thank you,
Chimed
