Como criar o visualizador Skia no MacOS arm64?

  • 772

Consigo criar o Skia, mas não consigo vincular o visualizador.

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
git clone https://github.com/google/skia.git
export PATH="$PWD/depot_tools:$PATH"
cd skia
python tools/git-sync-deps

bin/gn gen out/release --args="is_official_build=false skia_use_libjpeg_turbo_decode=false skia_use_libjpeg_turbo_encode=false extra_cflags_cc=[\"-frtti\"] target_cpu=\"arm64\""

ninja -C out/release skia
ninja -C out/release viewer

Erro:

    Considerando os símbolos indefinidos de codificação/decodificação, tente este gncomando:

    bin/gn gen out/release --args="is_official_build=false \
  skia_use_libjpeg_turbo_decode=true \
  skia_use_libjpeg_turbo_encode=true \
  extra_cflags_cc=[\"-frtti\"] \
  target_cpu=\"arm64\""
