TObject.h: No such file or directory

Asked by Keping Xie

When I run the mg5_amc with aMCfast, I always met a compilation error with "TObject.h: No such file or directory".
My setting is:
generate p p > w+ [QCD]
with fix_order = on,
And change iappl=1,
lhapdf
id=11000,
download "analysis_amcfast_root_pp_V.f" from aMCfast website https://amcfast.hepforge.org/examples.html
and set the "FO_analyse_card.dat" with
FO_ANALYSIS_FORMAT = root
FO_ANALYSE = analysis_amcfast_root_pp_V.o

The error report is
WARNING: A compilation Error occurs when trying to compile /home/keping/MG5_aMC/amcfast_test_1/SubProcesses/P0_dxu_wp.
The compilation fails with the following output message:
    g++ -O -I/home/keping/local/fastjet/include -c -I. -I../../FixedOrderAnalysis/ ../../FixedOrderAnalysis//rbook_be8.cc

Dear Keping,

You have to have ROOT installed and give the path in the FO_Analyse_card. Just like already explained in that card (at the bottom).

# When linking with root, the following settings are a working
# example on lxplus (CERN) as of July 2014. When using this, comment
# out the lines above and replace <PATH_TO_ROOT> with the physical
# path to root,
# e.g. /afs/cern.ch/sw/lcg/app/releases/ROOT/5.34.11/x86_64-slc6-gcc46-dbg/root/
FO_ANALYSIS_FORMAT = root
FO_EXTRALIBS = Core Cint Hist Matrix MathCore RIO dl Thread
FO_EXTRAPATHS = <PATH_TO_ROOT>/lib
FO_INCLUDEPATHS = <PATH_TO_ROOT>/include
FO_ANALYSE = analysis_root_template.o

Best regards,
Rikkert
