Options to use the {fmt} library in ROOT

[couet]

May be your question is similar to:

gSystem->Load() Vs. R__LOAD_LIBRARY with ACLiC

I have a library libABC.so which I want to use in a script which I run like so: root -x myscript.cxx+ In my .rootlogon.C, I have gSystem->Load("libABC.so"); Everything works as expect. But now, I don’t want to modify .rootlogon.C. Instead I want to use R__LOAD_LIBRARY inside the myscript.cxx like so: #include "ABC.h" R__LOAD_LIBRARY(libABC.so) This fails to link the library. How can I get same effect as having gSystem->Load("libABC.so") in rootlogon.C?
