fengtairui@fengtairui-virtual-machine:~/bestidiocs2024/ch03/sm3/sm3gmssl$ gcc -o testsm3 testsm3.c
/usr/bin/ld: /tmp/cc7SFvCK.o: in function `main':
testsm3.c:(.text+0x37): undefined reference to `sm3_init'
/usr/bin/ld: testsm3.c:(.text+0x62): undefined reference to `sm3_update'
/usr/bin/ld: testsm3.c:(.text+0x78): undefined reference to `sm3_finish'
collect2: error: ld returned 1 exit status
AI问答
这个错误信息表明你在编译 `testsm3.c` 文件时，链接器（ld）找不到 `sm3_init`、`sm3_update` 和 `sm3_finish` 这三个函数的定义。这通常是因为你没有正确地链接到包含这些函数定义的库。
SM3 是一种密码散列函数，通常需要一个库来实现这些功能。如果你已经有了一个实现了 SM3 算法的库，你需要确保在编译时链接到这个库。如果库是静态库（.a 文件），你可以使用 `-l` 选项来链接它。如果库是动态库（.so 文件），你可能还需要指定库的路径。
例如，如果你的库文件名为 `libcrypto.a` 或 `libcrypto.so`，并且它包含了 `sm3_init`、`sm3_update` 和 `sm3_finish` 这些函数，你可以这样编译你的程序：
```bash
gcc -o testsm3 testsm3.c -lcrypto
```
或者，如果库不在标准的库路径中，你可能需要使用 `-L` 选项来指定库文件的路径：
```bash
gcc -o testsm3 testsm3.c -L/path/to/library -lcrypto
```
如果 `sm3` 函数是某个特定库的一部分，那么你需要确保你有这个库，并且知道它的名称。如果这个库不是标准的，你可能需要下载或者构建它，然后按照上述方法链接。
如果你没有这个库，你需要找到提供 SM3 实现的库，或者自己实现这些函数。如果你使用的是某个特定的开发环境或框架，可能已经有现成的库可以使用。
