 ====== ROOT Issues ===== ====== ROOT Issues =====
 +===== Using MathMore lib =====
 +==== Problem ====
 +  * Using a function from the MathMore fails with the following error:
 +<​code>​
 +root [0] ROOT::​Math::​hyperg(3.,​2.,​4.,​-.23) ​
 +IncrementalExecutor::​executeFunction:​ symbol '​_ZN4ROOT4Math6hypergEdddd'​ unresolved while linking [cling interface function]!
 +You are probably missing the definition of ROOT::​Math::​hyperg(double,​ double, double, double)
 +Maybe you need to load the corresponding shared library?
 +</​code>​
 +
 +==== Solution ====
 +  * Be sure that you have executed '​setupATLAS'​ and '​lsetup ROOT'
 +
 +  * Load the MathMore library prior to executing your script / macro
 +
 +<​code>​
 +[root@sydui4 ~]# root -l
 +*** DISPLAY not set, setting it to hubble.physics.usyd.edu.au:​0.0
 +root [0]  gSystem->​Load("​$ROOTSYS/​lib/​libMathMore.so"​) ​
 +(int) 0
 +root [1] ROOT::​Math::​hyperg(3.,​2.,​4.,​-.23) ​
