Linux下，使用C/C++编写"静态链接库"的一个简单例子

throat

/* test_lib.h */
/* 2005/06/28,a.m. wenxy */
#ifndef _TEST_LIB_H
#define _TEST_LIB_H
int test_fun(int nCount);
#endif
/* end file */
// --------------------------------------------------------------------------------------
/* test_lib.c */
/* 2005/06/28,a.m. wenxy */
#include
#include
int test_fun(int nCount)
{
nCount ++;
printf("Oh, export from the static lib: test_lib.a\n");
return nCount;
}
/* end file */
// --------------------------------------------------------------------------------------
# makefile
# 产生静态函数库*.a
# ar rcs my_library.a file1.o file2.o
CC = gcc
BIN = test_lib.a
OBJ = test_lib.o
# -----------------------------
# 产生*.a静态库
# .PHONY : static_lib
$(BIN) : $(OBJ)
ar -r $(BIN) $(OBJ)
# -----------------------------
# 生成目标文件
test_lib.o : test_lib.c test_lib.h
$(CC) -c test_lib.c
.PHONY : clean
clean :
-rm $(OBJ) $(BIN)
# end makefile
// -----------------------------------------------------------------------------------------------
/* main.c */
/* 2005/06/28,a.m. wenxy */
#include
#include
#include
#include
/* static lib */
#include "test_lib.h"
/* 静态库里的函数 */
/* extern int test_fun(int nCount); */
int main(int argc, char *argv[])
{
int nTemp = 0;
nTemp = test_fun(nTemp);
printf("%d\n", nTemp);

printf("Run ...... [PID = %d]\n", (int) getpid());


return 0;
}
/* end file */
// ---------------------------------------------------------------------------------------------
# make file for application
# 2005/06/28,a.m. wenxy
CC = gcc
BIN = main
OBJ = main.o
$(BIN) : $(OBJ)
$(CC) -o $(BIN) $(OBJ) test_lib.a

main.o : main.c test_lib.h
$(CC) -c main.c test_lib.a
.PHONY : clean
clean :
-rm $(OBJ) $(BIN)
# end makefile
