Gracious Rooters,
I am a very new ROOT user working my way through a tutorial ("Getting
Started With ROOT") and I am having huge difficulties in the section dealing
with the TTree Viewer, for a can't seem to open it up.
In one version of the tutorial I am instructed to type in the following
command ("h21" is my sample tree):
tv=new TTreeViewer("h21");
Upon doing so, the following error appeared and not the TTree Viewer:
Error: No symbol TTreeViewer in current scope
FILE:/tmp/fileeYDORx_cint Line:1
Error: type TTreeViewer not defined FILE:/tmp/fileeYDORx_cint LINE:1
Warning: Automatic variable tv allocated in global scope
FILE:/tmp/fileeYDORx_cint LINE:1
Error: Undeclared variable tv FILE:/tmp/fileeYDORx_cint LINE:1
*** Interpreter error recovered ***
So, I found a different version of the same tutorial which gave a different
command for opening TTree Viewer:
h21->StartViewer();
When I entered this I got a seg violation:
*** Break *** segmentation violation
Root>
I also tried opening the TTree Viewer by right clicking on the tree ("h21")
in the object browser and selecting "StartViewer" from the menu... this also
produced a segmentation violation.
Since I am just learning ROOT I really have no idea how to approach this
problem... What am I doing wrong and how can I get through this?
(By the way, I am running version 3.00/06)
Regards,
Parker
