[ROOT] Eclipse

Hello ROOTers,

Does anyone know a good tutorial for ROOT development on Eclipse (a  
standard IDE) ?

I have been developing my ROOT libraries using Emacs and usual  
terminals, but now I am planning to use Eclipse. I have some previous  
experience of Eclipse with PyDEV plugin. However, there is little  
information about ROOT/Eclipse combination on the web.

Thanks in advance.

Have you looked at CEDET?

I know you were asking about eclipse, but since you mentioned Emacs, I 
couldn't resist. ;)

[ROOT] Building ROOT from source on Fedora 11

Hi ROOT users,

I tried building 5.24 and ran into this problem. So I tried the latest
trunk from svn for 5.25, but no luck. :(

It builds just fine without any errors (but a few warnings) with the
following options:

> Enabled support for asimage, astiff, builtin_afterimage,
> builtin_ftgl, builtin_freetype, builtin_pcre, builtin_zlib, cint5,
> cintex, exceptions, fftw3, genvector, gsl_shared, mathmore, memstat,
> minuit2, opengl, python, reflex, roofit, shadowpw, shared, soversion,
> ssl, tmva, unuran, xft, xml, xrootd.

When I open a TBrowser and browse a ROOT file with histograms everything
is fine. But after I save one of those histograms say as an image or a
ROOT macro and then try to close the TBrowser, ROOT segfaults. The
TBrowser window freezes, and the whole terminal becomes non-responsive.
The only way to kill every thing is to do `kill -9 <PID_for_root
PID_for_root.exe>'.

I have attached the error ROOT spits out on segfaulting as a text file.

My system specifications:
2.6.30.8-64.fc11.x86_64
ROOT 5.25/03
g++ (GCC) 4.4.1 20090725 (Red Hat 4.4.1-2)

Thank you for any insights into solving this.

I cannot reproduce this problem.
Could you compile ROOT in debug mode, then run the valgrind 
memory-checker on root.exe?

Re: [ROOT] Building ROOT from source on Fedora 11

Hi Rene,

Sorry for the delay, I am on the west coast of Canada. :\

I have attached a file with all the particulars about the build 
environment and the options I used to build ROOT. It also includes the 
backtrace from the segfault. I have also attached the log file generated 
by valgrind. I used the following command to attach valgrind to root.

>$ valgrind -v --log-file=valgrind-root.log root -l MonitorESD_91890_1.root

As reported earlier, after the segfault I had to kill ROOT with
$ kill -9 <PID_for_root PID_for_root.exe>

I also noticed that the segfault occurs only when I change something on 
the canvas using the histogram editor and try to close the TBrowser 
after saving it.

I hope this will help you track things down. Hopefully its not some 
stupid mistake on my part :-p

PS: If this makes any difference, the ROOT file was generated by ATHENA 
15.4.0.1 (ROOT version 5.22). It is full of TH1Fs, TH2Fs and TProfiles.

[ROOT] TTree Draw/Scan/Project

Hello,

i would have naive question

Let's consider 2 TTree

TTree *tree1;
TTree *tree2;

tree1 contains variable1
tree2 contains variable2

How to do (in the easiest way) something like :

tree1.Draw("variable1:variable2","easy condition on variable2")

if i do this last command, variable2 is not known whereas i don't do :
tree2.Draw("variable2")

i mean how to access from a tree a variable that is in another tree

thank you

Hi Marc,

Use tree1->AddFriend(tree2);

Cheers,
Philippe.

Re: [ROOT] Eclipse

Hello Jan,

Thank you for your replays. >> Jan and Suayu

> - Run configure manually.

This is a nice tip because I did not know how to run the configure  
script in Eclipse. In addition, I had some qustions. For example, I  
could not set environment variables, such as ROOTSYS and PATH, on my  
Mac, but now I figured out how to do it.

Mac's GUI application does not read my .zshrc when I launch it by  
double clicking. However, if I call /Applications/eclipse/eclipse from  
a terminal window, ROOTSYS was set properly in Eclipse.

I could not find the answers for these elementary questions on the web  
last week. But now I am enjoying developing on Eclipse with Subversive.
