我有以下两个项目:

`/home/jagbirs/Downloads/sample/SampleExtLib1` containing:

ext_lib1.c
ext_lib1.h
Makefile


/home/jagbirs/Downloads/sample/SampleMakeTest包含:

main.c
Makefile


我正在学习如何链接外部库。我在ext_lib1.h中有一个函数

在main.c中使用,但在make后出现以下错误:

gcc -o main main.c -L/home/jagbirs/Downloads/sample/SampleExtLib1 -lext_lib1
main.c:10:22: fatal error: ext_lib1.h: No such file or directory
compilation terminated.
make: *** [all] Error 1


这两个makefile如下:
SampleMakeTest / Makefile:

LIB = main
SRC := main.c
CFLAGS := -I../SampleExtLib1

all: $(SRC)
    gcc -o $(LIB) $(SRC) -L/home/jagbirs/Downloads/sample/SampleExtLib1 -lext_lib1

clean:
    rm -f *.o


SampleExtLib1 / Makefile:

all: ext_lib1.o
    ar r libext_lib1.a ext_lib1.o

clean:
    rm -f *.o *.a


可以请我帮忙弄清楚为什么链接不正确吗?
谢谢

最佳答案

尝试添加-I以包含库的.h文件:

gcc -o $(LIB) $(SRC) -I/home/jagbirs/Downloads/sample/SampleExtLib1 -L/home/jagbirs/Downloads/sample/SampleExtLib1 -lext_lib1
