linux c打印自己的程序

test.c

#include <stdio.h>
#include <stdlib.h>

extern char * _binary_test_c_start;
int main()
{
  printf("%s", (char *)&_binary_test_c_start);

  printf("hahah\n");
}

 

Makefile

SRC = test.c
TAR = test
ALL:test.c
        objcopy -I binary -O elf32-i386 -B i386 test.c test.bin
        gcc -o test test.c test.bin

 

objcopy很方便的可以把文本文件做成可以连接器可以连接的对象，进而链进可执行程序里面。

[root@kenthy c_par]# ./test
#include
#include

extern char* _binary_test_c_start;

int main()
{
  printf("%s", (char *)&_binary_test_c_start);
  printf("hahah\n");
  return 0;
}
hahah

有点小意思!!!都还没用过objcopy呢^_^
