Hi,
i have a problem compiling my project including root libraries.
This is my makefile:

main.x: main.o lib1.o lib2.o
	g++ -o main.x main.o lib1.o lib2.o `root-config --cflags` `root-config --glibs`
main.o: main.C lib.h
	g++ -c main.C `root-config --cflags` `root-config --glibs`
lib2.o: lib2.C lib.h
	g++ -c lib2.C
lib1.o: lib1.C lib.h
	g++ -c lib1.C

When I compile i see a list of error like these:
clang: warning: -lCore: ‘linker’ input unused [-Wunused-command-line-argument]
clang: warning: -lImt: ‘linker’ input unused [-Wunused-command-line-argument]
clang: warning: -lRIO: ‘linker’ input unused [-Wunused-command-line-argument]
The projects works but I don’t understand why I see these warnings.

Can you please provide the output of running make?

Try with (first “rm -f main.x main.o lib1.o lib2.o”):

main.x: main.o lib1.o lib2.o
	`root-config --cxx --cflags` -o main.x main.o lib1.o lib2.o `root-config --glibs`
main.o: main.C lib.h
	`root-config --cxx --cflags` -c main.C
lib2.o: lib2.C lib.h
	`root-config --cxx --cflags` -c lib2.C
lib1.o: lib1.C lib.h
	`root-config --cxx --cflags` -c lib1.C
