Hello,
I had some problems with root, i.e. when using the TBrowser I get a segmentation violation.
The output I get is this:
[code]Error in TGVScrollBar::TGVScrollBar: arrow_*.xpm not found
*** Break *** segmentation violation
[/code]
After having searched the forum I found some suggestions how to solve this problem, but none worked.
I tried installing root with the $ROOTSYS variable, as well as with the “prefix” option.
Both did result in the same segmentation violation.
Using TBrowser t; or TBrowser() or any other way to use a TBrowser ended with a segmentation violation.
Currently i have installed root with the $ROOTSYS option. The root version is the current cvs head from monday the 26 (before I had the official 5.14/00 version with the same problem) .
The system I am running here is a debian etch with a gcc version 4.1.2.
I checked that the icons are at the place where they should be $ROOTSYS/icons/ .
Also in $ROOTSYS/etc/system.rootrc is setup correctly:
Then I compiled with build=debug option and got from gdb this:
Program received signal SIGSEGV, Segmentation fault.

at gui/src/TGScrollBar.cxx:778
778 fSlider->MoveResize(0, fY0, fgScrollBarWidth, fSliderSize);
I didn’t understand what is wrong with this: fSlider->MoveResize(0, fY0, fgScrollBarWidth, fSliderSize);
Backtracing with gdb gave that output:

I hope someone can help me now, because I am stuck.
All help is highly appreciated.
Thanks,
