Question

我正在尝试使用WebRTC本机库在Qt Creator中构建Mac desktiop，但始终会看到错误消息：

    Undefined symbols for architecture x86_64:
  "_NSOSStatusErrorDomain", referenced from:
      rtc::DescriptionFromOSStatus(int) in libwebrtc.a(logging_mac.o)

初始参数：

Qt Creator基于Qt 5.10.0（Clang 7.0（Apple），64位）
编译器 - 针对libc ++的c ++ 11模式下的Clang（C ++ x86 64位）
MacOS - Sierra v.10.12.6
Xcode - 版本9.2（9C40b）
WebRTC - branch-heads / 63

在使用webrtc的编译选项后，我已经使用系统的clang编译并使用了libc ++。

我使用参数

构建了webRTC库

gn gen out / x64 / Debug --args ='is_debug = true target_os =“mac”is_component_build = false rtc_include_tests = false target_cpu =“x64”'
export GYP_DEFINES =“build_with_libjingle = 1 build_with_chromium = 0 libjingle_objc = 1 clang = 1 clang_xcode = 1 use_system_libcxx = 1 OS = mac”
export GYP_GENERATORS =“ninja，xcode-ninja”
export GYP_DEFINES =“$ GYP_DEFINES OS = mac target_arch = x64”
export GYP_GENERATOR_FLAGS =“$ GYP_GENERATOR_FLAGS output_dir = out / x64 / Debug”
ninja -v -C out / x64 / Debug

此外，经过大量谷歌搜索后，我在/ src / build /

中编辑了 common.gypi 文件

'xcode_settings': {
           'GCC_DYNAMIC_NO_PIC': 'NO',               # No -mdynamic-no-pic
                                                     # (Equivalent to -fPIC)
           'CLANG_CXX_LIBRARY': 'libc++',
           # MACOSX_DEPLOYMENT_TARGET maps to -mmacosx-version-min
                    }

'GCC_ENABLE_CPP_RTTI': 'YES',             # -fno-rtti

'GCC_TREAT_WARNINGS_AS_ERRORS': 'NO',     # -Werror

'CLANG_CXX_LIBRARY':           'libc++', # -stdlib=libc++

但不幸的是，结果错误是相同的!!!
