Hello, I am new to GiNaC and I follow a pdf doc tutorial that documents GiNaC 1.7.6 for installation and testing. However there is a inconsistency that I found in the pdf doc on how to compile the scripts. Not working : G++ HELLO.CPP -O HELLO -LCLN -LGINAC Works : G++ HELLO.CPP -O HELLO -LGINAC -LCLN Perhaps you should update the tutorial docs? I use Windows 10 and GCC 7.4.0. Thanks. Best regards, Hanni Puspita
