TCanvas constructor segmentation fault

ROOT
1

Hi,

I’m running ROOT 5.28/00a on an iMac (2.8 GHz intel Core 2 Duo, 3GB RAM) running OSX 10.6.6 and I’m consistently getting a segmentation fault in the TCanvas constructor. After configuring with --build=debug and recompiling I obtain the more detailed stack trace which I have attached.

I also tried to use the svn trunk version with the same result. I have a feeling this might be to do with X11, for which I use XQuartz instead of the default OSX X11 implementation. Could this be the problem?

Any help much appreciated.

Cheers,

Hugh

Hi,

yes this is the problem. Try running with the standard MacOS X X11 and it should work.

Unfortunately this did not solve the problem. Is the _Xreply() function part of ROOT or X11?

Any other ideas?

Cheers,

Do you have Fink or MacPorts X11 client libs around? That might be a problem too.

Cheers, Fons.

Indeed it was a MacPorts installation. In fact there are no problems using XQuartz instead of the default X11.app.

Many thanks for your help.

Hi,

I think i am experiencing some similar problems with the TCanvas constructor with a similar config :
Mac OS X 10.6.7
2.6 GHz Intel Core i7, 4 GB
ROOT 5.28/00
XQuartz 2.3.6

Unfortunately, I do not managed to understand where you get the solution of your problem.
You are talking about MacPorts installation… installation of Root via MacPorts ? Which libs are you talking about ? XQuartz ?

Could you detailed the whole thing a little bit more?

Thanks in advanced.
