@Vladimir, thanks but I do not prefer to install Homebrew or MacPorts as most of the time they affects due to broken packages and also much bulky. So I install whatever needed for my work from the source itself. In this case I have installed cln successfully but failed in installing Ginac.


@Isuru, after configure, in the Makefile I can see the following:

CPPFLAGS =  /Users/gkdgoutam/Softwares/HEP_Softwares/Install/Cln134/include:


CXXFLAGS = -g -O2
