I have multiple cpp files .i have a make file a makefile for compilation, but when i make all it gives me nothing to do
CC=g++
PWD=`pwd`
ARCH=$(shell uname -s)
CFLAGS=-Wall -g -fPIC
LIBSOURCES=./libsrc/Backup/BackupLib.cpp \
./libsrc/Backup/BackupBase.cpp \
./libsrc/Backup/TransferManager.cpp
LIBOBJECTS:=$(LIBSOURCES:.cpp=.o)
INCLUDE= -I /usr/include/libxml2/ -I ./System/ -I ./SubSystem/Queue/ -I ./System/Threads/ -I ./ -I
./SubSystem/DB/ -I ./Controller/ -I ./SubSystem/Watcher/
MYDEFINE=-D__LINUX__ -D__cplusplus -D__CLEARCACHE__
LIBFLAG=-shared -Wl
LDFLAGS=-ldl -lpthread -lsqlite3 -lcrypto -lssl -lxml2 -L ./lib/ -lBackupLib
LDLIBFLAGS=-ldl -lpthread -lsqlite3 -lcrypto -lssl -lxml2
all: $(LIBSOURCES) $(LIBCOMPBKUP)
$(LIBCOMPBKUP): $(LIBOBJECTS)
$(CC) $(CFLAGS) $(LIBOBJECTS) $(INCLUDE) $(MYDEFINE) -I ./libsrc/Backup/ -o $@
.cpp.o:
$(CC) $(CFLAGS) $(INCLUDE) $(MYDEFINE) -I ./libsrc/Backup/ ./$< -c -o ./$@
The output of make all cmd is make: Nothing to be done for `all'
I see no definition of LIBCOMPBKUP
.
So, the all
target expands to:
all: ./libsrc/Backup/BackupLib.cpp ./libsrc/Backup/BackupBase.cpp ./libsrc/Backup/TransferManager.cpp
and make
rightly concludes there's nothing to do.
Your all
target should just depend solely on $(LIBCOMPBKUP)
(once you correctly define it), and things should start working from there.
You need a line like:
LIBCOMPBKUP = BackupLib.so
or similar so that your rule to build $(LIBCOMPBKUP)
has some meaning.
