問題

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問答

這個錯誤信息表明你在編譯 `testsm3.c` 文件時，鏈接器（ld）找不到 `sm3_init`、`sm3_update` 和 `sm3_finish` 這三個函數的定義。這通常是因為你沒有正確地鏈接到包含這些函數定義的庫。

SM3 是一種密碼散列函數，通常需要一個庫來實現這些功能。如果你已經有了一個實現了 SM3 算法的庫，你需要確保在編譯時鏈接到這個庫。如果庫是靜態庫（.a 文件），你可以使用 `-l` 選項來鏈接它。如果庫是動態庫（.so 文件），你可能還需要指定庫的路徑。

例如，如果你的庫文件名為 `libcrypto.a` 或 `libcrypto.so`，并且它包含了 `sm3_init`、`sm3_update` 和 `sm3_finish` 這些函數，你可以這樣編譯你的程序：

```bash
gcc -o testsm3 testsm3.c -lcrypto
```

或者，如果庫不在標準的庫路徑中，你可能需要使用 `-L` 選項來指定庫文件的路徑：

```bash
gcc -o testsm3 testsm3.c -L/path/to/library -lcrypto
```

如果 `sm3` 函數是某個特定庫的一部分，那么你需要確保你有這個庫，并且知道它的名稱。如果這個庫不是標準的，你可能需要下載或者構建它，然后按照上述方法鏈接。

如果你沒有這個庫，你需要找到提供 SM3 實現的庫，或者自己實現這些函數。如果你使用的是某個特定的開發環境或框架，可能已經有現成的庫可以使用。
