使用 openssl 而不是 boringssl 时使用 webrtc 构建错误

Question

我正在尝试使用 openssl 而不是 boringssl 构建 webrtc 的稳定分支 57。这是我的命令：

gn gen out/Default --args="is_component_build=false rtc_build_ssl=false rtc_ssl_root=""C:\DevThirdParty\openssl-1.0.2k"""
ninja -C out/Default

但是，构建中途失败并出现以下错误：

[12/1633] CXX obj/webrtc/base/rtc_base/opensslstreamadapter.obj

这是来自 dtls1.h 的代码片段：

struct dtls1_retransmit_state {
    EVP_CIPHER_CTX *enc_write_ctx; /* cryptographic state */
    EVP_MD_CTX *write_hash;     /* used for mac generation */
#  ifndef OPENSSL_NO_COMP
    COMP_CTX *compress;         /* compression */   <=== LINE 139
#  else
    char *compress;
#  endif
    SSL_SESSION *session;                            <== LINE 143
    unsigned short epoch;
};

我还缺少其他步骤吗？问候。

原来问题出在 WebRtc 的 opensslstreamadapter.cc 文件中。包括列为：

#include <openssl/dtls1.h>
#include <openssl/ssl.h>

颠倒顺序编译成功
