Hi,
We have released a new patch release v6.10/06. See https://root.cern.ch/content/release-61006 for downloads, https://root.cern.ch/doc/v610/release-notes.html#release-6.1006 for release notes.
Note that this patch release cannot be built yet with Xcode 9. We will be publishing a new patch release likely next week that will take care of this.
To everyone who contributed with patches, pull requests and bug reports: thank you!
Axel,
for the ROOT team
This is Kubuntu 14.04.5 LTS / x86_64 with gcc 4.8.4 (so, running KDE desktop, if that matters) here.
I tried your newest Ubuntu 14 gcc4.8 binary release and it crashes as soon as I try to create a TCanvas or a TBrowser:
[...] $ which root
/opt/ROOT/releases/root_v6.10.06/bin/root
[...] $ root -l
root [0] new TCanvas
*** Break *** illegal instruction

That happened to me some time before, because some libraries were using
different versions, I fixed it by making use of soft links. Try “$ldd
$ROOTSYS/bin/root” and see if everything is Ok there
You should have been checking:
ldd ${ROOTSYS}/bin/root.exe
@Wile_E_Coyote I just started an ubuntu:10.04 container, installed the binary release, and I don’t see the problem you are reporting. Everything works fine for me. What kind of machine (hardware) are you running it on?
This is an old HP EliteBook 8530p laptop (4GB RAM) running an up-to-date Kubuntu 14.04.5 LTS / x86_64 with gcc 4.8.4 (nothing fancy is installed / added).
Note that, the newest ROOT 6.11/02 binary release (for Ubuntu 14 gcc4.8) behaves even worse.
Can you please check if you have SSE4.2 in your machine? What does
grep -o sse4.2 /proc/cpuinfo
give you? If this is the problem, I will make sure we do not enable that by default in future releases.
This is “Intel® Core™2 Duo CPU T9600 @ 2.80GHz” here, which seems to support “sse”, “sse2”, “ssse3” and “sse4_1” (so, no “sse4.2”).
Wow, well done, @amadio & @Wile_E_Coyote ! Okay, we’ll have to discuss what we do about this: either start an error during ROOT startup that we need a newer CPU or build ROOT without requiring SSE4.2. Thank you for reporting this (and the other one), WileE!
I vote for building without “sse4.2”.
I’m not surprised
