海思dv300cv500交叉编译webrtc

时间:2020-01-11 云中双月人气:0

　　感谢声网提供的webrtc国内源码镜像。

　　首先要安装好海思编译工具链和git。

　　先替换一下webrtc代码的仓库网址路径

　　(第一二句改一下哈，写的是我的)

　　然后选择一个文件夹作为工作目录，我们所有的东西都在这里搞。然后把depot_tools拉下来

　　代码为：

export WORKSPACE='/mnthttps://img.qb5200.com/download-x/d/webrtc'
cd $WORKSPACE
rm -rf depot_tools && git clone https://chromium.googlesource.com/chromium/toolshttps://img.qb5200.com/download-x/depot_tools.git

cd $WORKSPACEhttps://img.qb5200.com/download-x/depot_tools && git checkout gitlab
chmod +x $WORKSPACEhttps://img.qb5200.com/download-x/depot_tools/cipd
export PATH=$WORKSPACEhttps://img.qb5200.com/download-x/depot_tools:$PATH

　　然后拉取代码

　　代码为：

rm -rf $WORKSPACE/code && mkdir $WORKSPACE/code
cd $WORKSPACE/code && gclient config --name src https://chromium.googlesource.com/external/webrtc.git@gitlab

export CDS_CLANG_BUCKET_OVERRIDE=http://120.92.49.206:3232/chromiumsrc/commondatastorage/raw/master/public/chromium-browser-clang

cd $WORKSPACE/code && gclient sync --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab

　　(这个过程可能持续2个小时，因为拉取的代码有10个G)

　　然后生成解决方案（最好先把软件源换到阿里云，一共要通过apt-get下载960多个系统组件，你用ubuntu自带的源搞不定），而且最好切换到root，因为要用sudo，这个过程会持续一整天，如果不su，中途sudo的session过期可能导致你失败

　　代码为：

./build/install-build-deps.sh --no-chromeos-fonts

　　图中的gn参数为：

gn gen out/Release --args='target_os="linux" enable_iterator_debugging=false enable_profiling=false is_clang=false is_debug=false is_desktop_linux=false is_nacl_glibc=true libyuv_use_neon=true rtc_build_with_neon=true rtc_include_internal_audio_device=false rtc_include_pulse_audio=false rtc_libvpx_build_vp9=false rtc_use_gtk=false strip_absolute_paths_from_debug_symbols=true treat_warnings_as_errors=false use_aura=false use_custom_libcxx=true use_dbus=false target_sysroot="/opt/hisi-linux/x86-arm/arm-himix200-linux/target" use_gold=true use_goma=false use_lld=false use_ozone=false use_udev=false rtc_build_examples=false rtc_build_tools=false rtc_include_tests=false use_glib=false target_cpu="arm" rtc_use_x11 = false'

　　解决方案生成之后，需要把toolchain.ninja中的arm编译工具改为hisi的交叉编译链，然后直接编译

　　代码为：

ninja -C out/Release

　　编译完成之后，可以在$WORKSPACE/code/src/out/Release/obj中找到libwebrtc.a

　　其实整篇文章中，精髓在gn gen的参数，这个参数需要你自己调教出来。首先有几个你必须加入

target_os="linux"
target_sysroot="/opt/hisi-linux/x86-arm/arm-himix200-linux/target"
target_cpu="arm"
rtc_use_x11=false

　　如果不需要测试工程，下面的几个也可以加入

rtc_build_examples=false
rtc_build_tools=false
rtc_include_tests=false

　　其他的是我从google的论坛扒下来的（做了一些减法），不过我个人认为可能有些是不需要的，你应该先都不加，然后gn gen，如果报错，就去找到导致报错的模块，把它的编译选项关掉。下文我展示一下rtc_use_x11是怎么发掘的，给大家打个样

　　首先是不知道要加这个开关时，我们可以gn gen成功，但编译会报错，如下图

　　怎么排查问题，没别的办法，只有文件夹全局搜索

　　（注意，具体的调教过程可能没这么简单哈！你得稍微会一点gn）

　　（当然，linux下递归搜索可能要麻烦一些）
