当我想通过将Webrtc链接为静态库来构建对等连接示例时遇到了一些问题。
我的构建环境和目标都是ubuntu 18.04，我使用Github仓库https://github.com/vsimon/webrtcbuilds来构建 Webrtc作为静态库。
然后有很多关于absl libray的链接错误，在进行了一些调查之后，我添加了一些build args来消除其中的大部分，如下所示：
is_debug=false
is_component_build=false
is_clang=false
rtc_include_tests=false
rtc_use_h264=true
rtc_enable_protobuf=false
use_rtti=true
use_custom_libcxx=false
treat_warnings_as_errors=false
use_ozone=true
但是它仍然存在一些我无法解决的链接错误：

我希望任何人都能给我一些修复建议，非常感谢！
