我试图在官方网站上使用 the instruction编译WebRTC。当我输入命令ninja -C out/Debug时，我得到了一个巨大的错误清单。我猜想，提供整个列表是没有意义的，但是此字符串有几次出现：../../third_party/llvm-build/Release+Asserts/bin/clang++: 1:../../third_party/llvm-build/Release+Asserts/bin/clang++:Syntax error: "(" unexpected
我机器上的Clang版本：$ clang --versionUbuntu clang version 3.4-1ubuntu3 (tags/RELEASE_34/final) (based on LLVM 3.4)Target: i386-pc-linux-gnuThread model: posix
我不知道该怎么做。有人可以帮我吗？
UPD。整个错误清单：$ ninja -C out/Debugninja: Entering directory `out/Debug'[3/2955] CXX obj/webrtc/modules/remote_bitrate_estimator/remote_bitrate_estimator.remote_bitrate_estimator_abs_send_time.oFAILED:

最佳答案
请检查this article我描述了如何直接构建WebRTC。
下载脚本并运行
https://cs.chromium.org/chromium/src/build/install-build-deps.sh
./build/install-build-deps.sh --no-chromeos-fonts
$ git clone --depth 1 https://chromium.googlesource.com/chromium/tools/depot_tools.git$ export PATH=`pwd`/depot_tools:"$PATH"
定义建筑参数
$ export GYP_DEFINES="target_arch=x64 host_arch=x64 build_with_chromium=0 use_openssl=0 use_gtk=0 use_x11=0 include_examples=0 include_tests=1 fastbuild=1 remove_webcore_debug_symbols=1 include_pulse_audio=0 include_internal_video_render=0 clang=1 "
下载源代码
$ mkdir webrtc-checkout
$ cd webrtc-checkout
$ gclient config https://chromium.googlesource.com/external/webrtc.git@branch-heads/50 --name=src
$ gclient sync --force --with_branch_heads
$ gclient sync --force --with_branch_heads --nohooks
$ cd src
$ git checkout branch-heads/50
生成构建脚本
$ rm -rf ./out/
$ gclient runhooks
编译
$ ninja -C ./out/Release
现在生成完整的库和标题
