This is the whole project directory tree, want to will be generated under the fun. O file under the obj/fun, main. O under the obj/main



Compilation problems is currently in the fun is only one directory. C file, compile is ok, but there are multiple. C, will only generate a compilation. O file, feeling is there is something wrong with the fun of makefile

The total Makefile

 
# define GCC 
CC: GCC=
CFLAGS=- g - O - Wall - pthread 
SUBDIRS:=the main SRC obj 
INCDIR: -i=$(shell PWD)/SRC/fun/inc 
PRJDIR:=$(shell PWD) 
BIN_DIR:=bin 
BIN:=my_app 
OBJS_DIR: obj=
RM: RM=
Export CC OBJS_DIR BIN_DIR BIN INCDIR PRJDIR LIB 
All: check_bin compile_src 
Check_bin: 
Echo $(PWD) 
The mkdir -p $(BIN_DIR) $(LIB) 
Compile_src: 
@ the set - e; For I in $(SUBDIRS); Do $(MAKE) - C $$I; The done 
PHONY: clean cleanall 
Clean: 
$(RM) - rf $(OBJS_DIR)/*. O $(OBJS_DIR)//*. * * o 
Cleanall: 
$(RM) - rf $(OBJS_DIR)/*. O $(OBJS_DIR)//*. * * o $(BIN_DIR)/$(BIN) 

Under the SRC Makefile

 
SUBDIRS:=fun 
All: compile_src 
Compile_src: 
@ the set - e; For I in $(SUBDIRS); Do $(MAKE) - C $$I; The done 

Under the fun of Makefile

 
SRC=$(wildcard * */*. C) 
OBJS:=$(addprefix $(PRJDIR)/$(OBJS_DIR)/fun/, $(patsubst %. C, % o, $(notdir $(SRC)))) 

$(OBJS) : $(SRC) 
@ mkdir -p $(PRJDIR)/$(OBJS_DIR)/fun 
$(CC) $(INCDIR) - c $& lt; -o $@ 

Feel $(OBJS) : $(SRC) this compilation is wrong, changed to
$(PRJDIR)/$(OBJS_DIR)/fun/%. O: SRC/%. C
Still is not correct, to ask how to write here

CodePudding user response:

Must add in the makefile under the fun of target depends on
Compile_src: $(OBJS)

CodePudding user response:

%. O: c
%.$(CC) $(INCDIR) - c $& lt; -o $(PRJDIR)/$(OBJS_DIR)/fun/$@

Fun Makefile, to try this, command before the CC thus add & lt; TAB>
