I have this working macro, btagging.c, attached here, which reads branches in a TChain successfully, and I would like to compile it to run faster on larger samples.
btagging.c (14.6 KB)
I created the simplest possible Makefile (attached)
Makefile.txt (133 Bytes)
and adjusted a few syntax details (added cmath include, change exit statements to return, add namespace statement at the top, and move to int main() appellation, see attached file btag_comp.c).
btag_comp.c (11.3 KB)
It compiles fine but seg faults when starting to read the branches. I tried many options in a slightly chaotic order, but none prevailed. Can anybody point me to the main transitions needed to have this executable running? Looking at a good old MakeCode output, what I am doing here doesn’t look so different. Also, note that this tree contains more branches than the ones listed in the code, but I only setup those that I need later on.
Many thanks in advance,
