TBrowser not opening (segmentation violation)

ROOT
1

Hi,

I installed root (6.18 for mac) through

conda install root root-binaries root-dependencies root_base

and everything worked great. Now suddenly when I try to open the TBrowser in my shell I get a segmentation violation:

 *** Break *** segmentation violation

What does it mean and what could be the cause of the problem?
I do not see what I could have changed somehow.

You mean it was working before and now it doesn’t work anymore? Did you update your system? Did you update XCode? Maybe a MacOS user (@couet ) could give more details about what to check?

I build ROOT from sources on my Mac. I do not see such problem with TBrowser.
You might want to reinstall ROOT if you have updated the system or Xcode ?
You have the problem only with TBrowser ?
Also we are now at 6/.22 version … you might want to take a newer version if you update ROOT.

Yes it worked before… Don’t think I updated anything.
As far as I have checked only the TBrowser is not working properly.
I used installation through conda because my python and all the libraries are installed through the anaconda distruibution and I wanted to use pyROOT. It installs root 6.18 when I use

conda install root root-binaries root-dependencies root_base

Can I update the version afterwards?

I got an old Version (root 5.3) also installed. There everything works fine.

If nothing changed I have no idea why it started crashing suddenly.
May be do a new install ?
