gclient sync ERRO and gn args out/Default ERRO

[HYRobin]

My steps as follows:

step 1: export XWALK_OS_ANDROID=1 step 2: gclient config --name src/xwalk https://github.com/ks32/crosswalk.git@origin/ks_chromium_58 step 3: echo "target_os = [ 'android' ]" >> ./.gclient step 4: gclient sync ERRO: { Traceback (most recent call last): File "src/xwalk/tools/fetch_deps.py", line 83, in sys.exit(main()) File "src/xwalk/tools/fetch_deps.py", line 78, in main deps_fetcher.DoGclientSyncForChromium() File "src/xwalk/tools/fetch_deps.py", line 53, in DoGclientSyncForChromium gclient_utils.CheckCallAndFilterAndHeader(gclient_cmd, AttributeError: 'module' object has no attribute 'CheckCallAndFilterAndHeader' Error: Command 'vpython src/xwalk/tools/fetch_deps.py -v' returned non-zero exit }

instead of gclient sync --verbose --reset --force --with_branch_heads --delete_unversioned_trees --gclientfile=.gclient-xwalk is successful.

step 5: cd src ./build/install-build-deps.sh ./build/install-build-deps-android.sh

step 6: gn args out/Default { import("//xwalk/build/android.gni") is_debug = false target_os = "android" target_cpu = "arm" }

got erro:

{ Waiting for editor on "/home/crosswalk/src/out/Default/args.gn"... Generating files... ERROR at //media/BUILD.gn:35:3: Assertion failed. assert( ^----- proprietary codecs and ffmpeg_branding set to Chromium are incompatible See //media/BUILD.gn:36:7: ffmpeg_branding != "Chromium", ^---------------------------- This is where it was set. See //BUILD.gn:297:7: which caused the file to be included. "//media:media_unittests", ^------------------------ }

please help me ,how to solve this problem. is there any step i omitted ?
