makefile编写---.a静态库的生成和调用

ranlib $(Lib_Dir)$(Lib)

clean:
rm *.o

.PHONY:clean

#$(objects) == $^
#edit:$(objects)

#$(TARGET): $(OBJS)
# $(CC) $^ -o $@ $(INCLUDE) $(LFLAGS)

main.o:main.c alg.h
$(cc) -c main.c

clean:
-rm *.o $(target)

这里的main调用库不能以系统文件形式包含

/***********************以上是ok的********************************/

bug1：

CLib = -L. inilib.a //这里没加-l

$(Target): $(Cobjects)
$(GCC) $(CLib) -o $@ $^

上面的顺序会导致错误如下

gcc -L. inilib.a -o TestIni main.o
main.o: In function `main':
main.c:(.text+0x35): undefined reference to `iniParser_init'
main.c:(.text+0x154): undefined reference to `iniParser_getString'
main.c:(.text+0x1b4): undefined reference to `iniParser_setString'
main.c:(.text+0x1c9): undefined reference to `iniParser_uinit'

solve1：

是依赖库.a 放错位置

$(Target): $(Cobjects)
$(GCC) -o $@ $^ $(CLib) 这样就可以通过

bug2：

CLib = -L. -linilib.a

$(Target): $(Cobjects)
$(GCC) -o $@ $^ $(CLib) //

root@ubuntu:/opt/54/app/ini/inifileok/iniapi# make -f Makefiles all
gcc -L. -linilib.a -o TestIni main.o
/usr/bin/ld: cannot find -linilib.a
collect2: ld returned 1 exit status
make: *** [TestIni] 错误 1

solve2：

CLib = -L. inilib.a //去掉-l 而且这里-L. 就是表示在当前目录加载路径

下面的静态库生成，调用是可以的

create：

Target = TestIni
TargetLib = inilib.a
GCC = gcc
G++ = g++

CInc = $(wildcard *.h)
CSrc = $(wildcard *.c)

Cobjects =$(CSrc:%.c=%.o)
#Cobjects =$(patsubst %.c,%.o,$(CSrc))

lib:$(TargetLib)

release:$(Target)

$(Target): $(Cobjects)
$(GCC) -o $@ $^

$(TargetLib): $(Cobjects)
ar ruv $(TargetLib) $^
# ar rcs $(TargetLib) $^
