[c/c++] linux c生成静态库&共享库

静态库

libdemo.h

1 // libdemo.h
2 #ifndef _LIBDEMO_H
3 #define _LIBDEMO_H
4
5 void demo_call(char *msg);
6
7 #endif

libdemo.c

1 // libdemo.c
2 #include "libdemo.h"
3 #include <stdio.h>
4
5 void demo_call(char *msg)
6 {
7     printf("%s\n",msg);
8 }

编译库文件

# 编辑成目标文件
gcc -c libdemo.c -o libdemo.o
# 创建存档文件
ar rcs libdemo.a libdemo.o

测试文件testdemo.c

1 #include "libdemo.h"
2
3 int main()
4 {
5     demo_call("hello");
6     return 0;
7 }

gcc testdemo.c -o testdemo -static -L. -ldemo
./testdemo

共享库

gcc -fPIC -g -c libdemo.c -o libdemo.o
gcc -g -shared -WL,-soname,libdemo.so -o libdemo.so.1.0.0 libdemo.o -lc
ln -s libdemo.so.1.0.0 libdemo.so
gcc testdemo.c -o -L. -ldemo
# 为了能让./testdemo执行需要将.so 加入到库里
export LD_LIBRARY_PATH=$(pwd)
./testdemo
