使用 PjSip {PJSUA} 编译 Opus 库时出错
Error while Compiling Opus Library with PjSip {PJSUA}
我正在尝试编译和构建 PjProject {PJSUA}，其中包含 音频和视频支持。但是每次都陷入错误Unresolved_External_Symbols.
我正在使用 Visual Studio 2022 为 Windows-32-BIT 构建此项目，工具链设置最新版本 v143。
我想初始化各种编解码器{OPUS、OPENH264、FFMPEG、OPENSSL、SDL 等}。我只问 OPUS LIBRARY.
步骤如下：
已获取最新版 PjProject 的源码并于 Visual Studio 2022 年加载项目。
在编译和构建 LibOpus 后提及 Opus Include 目录和 Opus Library 目录。
将 PJSUA 作为源项目并将配置设置为 Debug-Static-Win32 并开始构建项目。
注意
- SDL 头文件和 lib 文件等其他附加依赖项已包含在内。
- 已经使用config_site.h定义编解码器使用{#define PJMEDIA_HAS_OPUS_CODEC 1}
我在错误日志中收到的错误如下：

我能否找到一种更简单的方法，以便我可以通过保存它来消除所有这些错误，并编译和构建我的 PJSUA，其中包含 OPUS CODEC。
经过长时间的尝试，我得到如下解决方案：
- 在config_site.h中我们需要提及并激活我们的编解码器以进行编译#define PJMEDIA_HAS_OPUS_CODEC
#define PJMEDIA_HAS_OPUS_CODEC 必须在整个程序和剩余函数行中处于活动状态，即 #define PJMEDIA_HAS_OPUS_CODEC 1 必须从程序中明确删除，以便于编译，这将忽略在构建过程中调用的不同函数。
I would still refer that while building on windows use Microsoft Visual Studio latest Version along with the latest toolset to compile and built different programs for a Single Linker.
