TDLib编译错误

今天编译TDLib，出现了以下错误：

td/tdutils/td/utils/crypto.cpp:899:25: error: too few arguments to function ‘int EVP_MAC_init(EVP_MAC_CTX*, const unsigned char*, size_t, const OSSL_PARAM*)’
  899 |   res = EVP_MAC_init(ctx);
      |                         ^

 1179 | int EVP_MAC_init(EVP_MAC_CTX *ctx, const unsigned char *key, size_t keylen,
      |     ^~~~~~~~~~~~

应该是我安装的OpenSSL版本太新导致的（编译安装）。

搜索得到EVP_MAC_init的文档，里面提到：

int EVP_MAC_init(EVP_MAC_CTX *ctx, const unsigned char *key, size_t keylen,
                  const OSSL_PARAM params[]);

If key is NULL, the key must be set via params either as part of this call or separately using EVP_MAC_CTX_set_params().

于是做如下修改：

diff --git a/tdutils/td/utils/crypto.cpp b/tdutils/td/utils/crypto.cpp
index 7b033ad0..a342b75c 100644

   res = EVP_MAC_update(ctx, message.ubegin(), message.size());

编译成功（也不知道对不对）。
