Hi all,
I have a question concerning migration from CINT to g++.
Usually I am using root to load and execute macros with my tasks
for analysing data. So, I am using cint interpreter.
But currently I am interested to make a stand-alone program and thus use g++ for compiling.
So, I wrote a makefile (see attachment) and compiled my program. But when I am trying to execute it, it fails with segmentation error on loading libraries. I figured out, that the problem is in libParBase library in CbmRuntimeDb class. It fails when trying to access variable 'contFactories' (static TList) in function 'addContFactory'.
I can't find the reason why when I load this library under ROOT session all works perfectly.
So, if anybody has any suggestion how to make it work (if is it actually possible?), I would be very grateful.
Regards,
Konstantin

Well, the problem probably is occurs due to the following:
There are some dependencies between this libraries. And when I am loading libraries not in the proper order - some of the static member are not initialized. And when on loading library constructor of this library is executed, segmentation error appears.
This is only guess - but it seems to be the true.
