Segmentation Fault vectors

[gherbert]

Hello,

I’m fairly new to Root and c++ but I’m trying to write a macro that produces a root file containing histograms.
However currently I’m getting a segmentation fault and I don’t really know why.
If anyone could help that would be great.
I have one idea: I’m appending data to vectors, but think that they may be getting too large. But I’m really new to this so I’m not exactly certain.
Many thanks,
Geoff Herbert.

All sorted now.
Thank you for your help.

PS. Many errors in the code. Dont bother trying to fix it. I’ve managed to get it working.

Hi,

generally it’s worth getting .x final1.C+ to work (note the trailing “+” which invokes your compiler).

Cheers, Axel.
