Hi,

I am sorry to read ROOT did not work out of the box for you.

Could you please check if BAT correctly includes the necessary header file? ROOT: math/mathcore/inc/Math/Util.h Source File

Cheers,
Danilo

Thanks for your reply. I have already added options like -I/..../root/install/include in the compilation options, but I’m not sure if this means the util header file has been successfully included. I also tried adding root-config --glibs --cflags directly to the compilation options, but it didn’t solve the problem."

Solved. I add #include <Math/Util.h> in the BCIntegrate.cxx and redo the cmake and make.
