Errors in compiling a macro

[Kamal_Kumar]

Hi everyone, I am new to Root. I was compiling a macro available in tutorials named Bessel.C, but it is showing some errors.

Info in TUnixSystem::ACLiC: creating shared library /home/kamal/./Bessel_C.so
In file included from /home/kamal/Bessel_C_ACLiC_dict.h:34:0,
from /home/kamal/Bessel_C_ACLiC_dict.cxx:17:
/home/kamal/./Bessel.C: In function ‘void Bessel()’:
/home/kamal/./Bessel.C:36:20: error: ‘libMathMore’ was not declared in this scope
R__LOAD_LIBRARY(libMathMore);
^
/home/kamal/./Bessel.C:36:31: error: ‘R__LOAD_LIBRARY’ was not declared in this scope
R__LOAD_LIBRARY(libMathMore);
^
g++: error: /home/kamal/Bessel_C_ACLiC_dict.o: No such file or directory
Error in : Compilation failed!

I get similar errors on TGraphErrors and Tgraph also while compiling other codes. Could you please help me out.

error: ‘libMathMore’ was not declared in this scope

It seems, that in your root version the MathMore library is missing. How did you install your root? Did you compile it with -Dmathmore:bool=ON?

Waldi,
I din’t install it using -Dmathmore:bool=ON command. I simply downloaded the source and ran
./configure --all
cmake
make -j 4
source ./bin/thisroot.sh commands.

You can just do

cmake -Dmathmore:bool=ON

hope it helps
