Thanks Philip,
I want to compile objects in order of the writting: y.o z.o x.o . The order of compiling x.o are different in below three cases. I don't understand the difference. x : y.o z.o x.o # compiles x.o last $(CC) $^ -o $@ # with recipe x : y.o z.o # compiles x.o last x : y.o z.o x.o # compiles x.o first My purpose is to keep my Makefile simple. With the patsubst function in Makefile, I just put Makefile with my source files and need to do nothing. It just compiles. But this is gone if the order of compiling matters. x : $(patsubst %.c,%.o,$(wildcard *.c)) Thanks --- # My Minimal Makefile for C, C++ # build shared library with -fPIC, -shared CFLAGS = -Wall -Wextra -g # -O3 -fPIC # CXXFLAGS for .cpp LDFLAGS = # -L../hello # -shared LDLIBS = # -lhello CPPFLAGS = -MMD -MP # -I../hello #CC = $(CXX) # link with CXX for .cpp # target name is basename of one of the source files main : $(patsubst %.c,%.o,$(wildcard *.c)) # .cpp -include *.d clean : ; -rm -fr *.o *.d .PHONY : clean
