TBrowser crashing in ubuntu

ROOT
1

Hi, this may be a stupid question, but I can’t run a TBrowser from the command line or script in root 5.08 and 5.10, compiled on ubuntu/debian breezy (g++ 4.02).

When I run:

on the command line, the browser appears but does not respond to clicking. Also the command line continues to throw out segmentation faults, and doesn’t respond to control+c. The only way to get rid of it is to close the terminal altogether.

This used to work with root 4.08.

one the segfaults:

What I can do to make this work?

Hi,

first of all could you try with the cvs head version. Next when you rebuilt can you use ./configure --enable-debug and trace the segv in gdb. Let us know.

Cheers, Fons.

Oops, must be ./configure --build=debug

I installed the CVS head. It still segmentation faults, but I can operate the window, in the sense that I can open the roll down menus and use the one called “close ROOT”. Which it does.

it then spills out an error:

Error in <TGHScrollBar>: arrow_*.xpm not found Error in <TGVScrollBar>: arrow_*.xpm not found

The files seem to be there:

locate arrow |grep root

gives:
/home/andrzej/cern/root/icons/arrow.xpm
/home/andrzej/cern/root/icons/arrow_down.xpm
/home/andrzej/cern/root/icons/arrow_left.xpm
/home/andrzej/cern/root/icons/arrow_right.xpm
/home/andrzej/cern/root/icons/arrow_right2.xpm
/home/andrzej/cern/root/icons/arrow_up.xpm
/home/andrzej/cern/root/tutorials/arrow.C

and just in case:

env |grep ROOT gives
CVSROOT=:pserver:cvs@root.cern.ch:/user/cvs
ROOTSYS=/home/andrzej/cern/root

I’ll start with the build_debug option now.
Thanks for the quick response.

I recompiled the newest cvs with the debug option. I’m not sure if I did the right thing with gdb, but I managed to get the first segmentation error message (test.C , has one line of code: void test() { TBrowser bb;} ):

I tried running it from the root/icons directory and setting the PATH variable, in case the problem is the path to the icons, but it still doesn’t work.

Andrzej.

I also tried with the debian packages (make debian). Same effect.
Does anyone have any idea what the problem is?
Thanks,
Andrzej

I struggled with Root and Ubuntu for some time. The more and more I wanted to do analysis and coding (i.e. real computing), Ubuntu had more and more problems. In the end, I decided to scrap Ubuntu and move to Scientific Linux – this is my best suggestion. If you are determined to use Ubuntu then I do have a suggestion to build root.

I compiled a working version by obtaining the source using apt. You just need to get the repository for it. Once you get the source from apt then build it. For some reason the source from Root pages always gave me problems.

Good luck

Could you clarify what is the difference between the source from apt
and the source from the ROOT pages?

Rene

10

This is what I do understand at all. Rather than investigate why I could compile and run root properly using the source obtained from apt repository, I just opted to switch to a different Linux dist. I believe the problem lies in using Ubuntu, not in Root. The reason for this can only be undercovered by the experts.
Check with the person who maintains the Root repository for debian. If I can remember who this is, I’ll post here.

Hi Andrzej,

First off. let me say that that I do not see any of these problems. I use a rather recent check-out, and the packages I build.

The packages (and sources) are available from

[quote] deb mirror.phy.bnl.gov/debian-root unstable root
deb-src mirror.phy.bnl.gov/debian-root unstable root
[/quote]
(see also http://mirror.phy.bnl.gov/debian-root for more information).

There are some differences between Ubuntu unstable and Debian unstable - these could be crucial - in particular differences in X. Debian unstable now uses X.org 7.0, and the default C++ compiler is GCC 4.0.2.

Now, since Ubuntu generally uses pretty new libraries for all stuff, it could be a bug in some of those libraries. It could also mean, that ROOT is not compatible with one of the newer libraries. It’s really hard to tell. That is, it doesn’t necessarily have to do with Ubuntu.

To really track down the problem, I think you need to figure out where and why you get the warnings

[quote]Error in : arrow_.xpm not found
Error in : arrow_.xpm not found
[/quote]

It could be that the icon path is not set properly, or something like that, either in the code, or in your .rootrc file.

There’s definitely a problem in gui/src/TGScrollBar.cxx. It reads

[code] fHeadPic = fClient->GetPicture(“arrow_left.xpm”);
fTailPic = fClient->GetPicture(“arrow_right.xpm”);

if (!fHeadPic || !fTailPic)
Error(“TGHScrollBar”, “arrow_*.xpm not found”);

fHead = new TGScrollBarElement(this, fHeadPic, fgScrollBarWidth, fgScrollBarWidth,
kRaisedFrame);
fTail = new TGScrollBarElement(this, fTailPic, fgScrollBarWidth, fgScrollBarWidth,
[/code]

The error should probably be more serious.

Do note, that make debian creates DEB packages that you need to install. Please note, that you need to unset ROOTSYS and remove the corresponding bin and lib directory from your PATH and LD_LIBRARY_PATH environment variables.

Regarding the differences between the upstream sources and the sources used by Debian: Currently the differences are very few. I’ve sent a patch to Fons some time ago with those fixes. They had mainly to do with some of the packaging scripts i.e., no real code changes. I’ve attached the files to this post.

Yours,

Christian

I tried to install the debian sources fom the repositories and build them :
apt-get -b
to build I had to install a lot of other packages, and since really new ones were required, I upgraded to dapper (current unstable ubuntu release).

I was unable to build the packages because an error was thrown at me, if I remember right:
Can’t stat /debian/tmp/usr/include/MySqlResult.h

This happens (I think) at the end of the build. The file exists in the source directory, but since I don’t know much about building packages in debian I don’t really know where to look to fix this problem.

The good news is that just to check I recompiled root in the standard way, and it seems that the upgrade to dapper made it work. I can open a TBrowser. Yes!

Thanks for all the help, also if I can provide any troubleshooting information let me know.
cheers,
Andrzej

Perhaps you want to do apt-get build-dep root first, to pull in all the build dependencies.

Are you sure that’s the error you got? `/debian/tmp’ is most likely not a place you can write to, and the there’s no such header in ROOT. There’s a header called TMySQLResult.h. If that’s the one it’s complaining about, then are you sure you got the libmysqlclient15-dev package installed?

It would be nice if you could post a log file of the build. If you used debuild, then you’d get the file root_5.11.03-3.i386.build that contains a log. Otherwise, you can do

apt-get -b root 2> /dev/stdout | tee build.log

I know there’s been an issue with awk on Ubuntu. You need to get the GNU one.

Good. Did you get the plugin libMySQL.so? If not, the error above might be due to a missing libmysqlclient15-dev installation.

A build log would go a long way :slight_smile:

Yours,

Christian

I’ll try that one next time, but for instance ruby1.8 was not available in breezy so I had to upgrade

my mistake, it was debian/tmp … (without the first slash). I checked this directory and the file is not there.

Ok. I have mysql installed, because I’m also using a different program that links to libmysqlclient and that works. Also I tried installing the Root mysql plugin, but the error was the same. The command to generate the build log that I used was:

root@nbandrei:/home/andrzej/cern/root-deb# apt-get -b source root root-common root-doc root-framework root-plugin-asimage root-plugin-fftw3 ttf-root-installer libroot-dev libroot5.11 2> /dev/stdout | tee build.log

I’m attaching the build log.

I get a similar problem on my Ubuntu 6.06 amd64 with gcc 4.0.3 and root 5.12.00
downloaded as a source from CERN website and compiled the usual (not the debian) way:

and so on…
The segmentation fault isn’t weird, cause the first browser crashed and didn’t clean up.
But why doesn’t it see the icons? They’re were they should be (/usr/local/share/root/icons).
Oh, two more details:

  1. the Browser doesn’t show up even for a second (in case someone was interested)
  2. When I draw a TF1 I get:
root [4] TF1 f1("func1","sin(x)/x",0,10)
root [5] f1.Draw()
Error in <TGHScrollBar>: arrow_*.xpm not found
Error in <TGVScrollBar>: arrow_*.xpm not found
<TCanvas>: created default TCanvas with name c1

And the canvas shows up allright.

Maybe it’s a problem with some config file or something?

17

When you compile ROOT with a particular prefix, the assumption is, that the icons will be in /share/root/icons. However, if you set the environment variable ROOTSYS=, then the assumption is that the icons will live in /icons (as in the source directory - sigh).

If you prefer ROOT should look for icons in different places, pass configure the appropriate options.

Hence, the solution for you should be to unset the environment variable ROOTSYS, and simply add /usr/local/bin to your PATH environment variable.

Note, if you pass configure the option –enable-rpath then you don’t need to set LD_LIBRARY_PATH either.

Yours,

Christian

I’m a bit confused, cause after gEnv->Print() I get:

19

OK, if that’s not the problem, then I’m a bit at a loss here. Perhaps you could run ROOT in GDB, and break in the line where it’s trying to get the pixmaps and investigate what’s going on. Perhaps you need to build ROOT with `–build=debug’ passed to configure.

20

i know this is an old thread but i had this problem on kubuntu. simply doing this solves the problem:
tar zxvf root.tar.gz
cd root
./configure --prefix=/usr/local
make
sudo make install

In my .bashrc, I add:
export LD_LIBRARY_PATH=/usr/local/lib/root:$LD_LIBRARY_PATH

and the problem is solved.
