Thanks a lot, your last tip (replace files in /usr) saved my day!

I recommend to stick to MacPorts. It will be the easiest way. Only for some really good reasons you should think of compiling such libraries.

Cheers,

Hi Jesko,

I am a newbie with my first Mac running across this problem.

Could you explain how to carry out option 3 step-by-step?

Just a comment if someone has problems with glib and libiconv: I had some problems building glib on OS X 10.6 and found out that it works if going back to glib version 2.22.5. Well, did had time to figure out why, but it works for me.

Comment on Minimal histograms with PyRoot and Python by Jesko Merkel

Hi Miguel,

‘-b’ is the batch mode option for root. If you want to use it with python just hand
it over to sys.argv before you load the ROOT module in a python script:

import sys
sys.argv.append(‘-b’)
import ROOT

This implies that it also work from command line like:

> python blablub.py -b

Cheers,

Jesko

Hmm. I reinstalled and “jhbuild build libiconv” didn’t work this time. Jesko’s solution 3 worked nicely.

Comment on Using PyRoot to write a TTree by David

Formatting removed my angled brackets…

# Create a struct
gROOT.ProcessLine(\
“struct MyStruct{\
vector[Double_t];
};”)

Thanks for the help.

One question.

How would you add a branch for container objects like std::vector?

I thought perhaps something along the lines of,

# Create a struct
gROOT.ProcessLine(\
“struct MyStruct{\
vector;
};”)

t.Branch(‘rootDouble’,AddressOf(s,’someVec’),’someVec/D’)

# Fill tree
for i in range(100):
s.someVec = [i, i+1, i+2]
t.Fill()

Hello.
Can you help me with one question?
If I create a canvas

c1 = ROOT.TCanvas(“c1″,”c1″,800,800)

inside my python program, I have a print out of it. Do you know how do I turn this off? What is the equivalent in pyroot of the -b option when we run root?

Thanks for your example
