android - 为 Android 编译 PDFium 的正确选项是什么？

Question

我正在尝试为 Android 构建 PDFium。我正在使用 Debian stretch。

我执行了以下命令:

> mkdir build
> cd build
> mkdir build/source
> cd source
> gclient config --unmanaged https://pdfium.googlesource.com/pdfium.git
> echo "target_os = [ 'android' ]" >> .gclient
> gclient sync
> cd pdfium
> build/install-build-deps-android.sh

安装依赖项后，我执行了此操作:

> gn args wx/arm64/release

我把这些作为参数

# Build arguments go here.
# See "gn args <out_dir> --list" for available build arguments.
target_os = "android"
target_cpu = "arm64"  # See "Figuring out target_cpu" below
use_goma = false  # Googlers only. Make sure goma is installed and running first. 
is_debug = false  # Enable debugging features.  
# Set true to enable experimental Skia backend. 
pdf_use_skia = false 
# # Set true to enable experimental Skia backend (paths only). 
pdf_use_skia_paths = false  
pdf_enable_xfa = false  # Set false to remove XFA support (implies JS support). 
pdf_enable_v8 = false  # Set false to remove Javascript support. 
pdf_is_standalone = true  # Set for a non-embedded build.  
is_component_build = true # Disable component build (Though it should work) # 
clang_use_chrome_plugins = false  # Currently must be false.
use_cxx11_on_android=false

当我退出编辑器时，出现以下错误:

ERROR Unresolved dependencies.
//:pdfium_embeddertests__exec(//build/toolchain/android:android_clang_arm64)
  needs //build/android:cpplib_stripped(//build/toolchain/android:android_clang_arm64)
//:pdfium_unittests__exec(//build/toolchain/android:android_clang_arm64)
  needs //build/android:cpplib_stripped(//build/toolchain/android:android_clang_arm64)

你能帮帮我吗？你对我在这里犯的错误有什么想法吗？这是错误的配置吗？缺少依赖项？

非常感谢您能给我的任何帮助。

我会回答我自己的问题，以防其他人遇到同样的问题。这是 Pdfium 构建脚本中的一个问题。

这现在已在 Pdfium/master 中修复(感谢 Pdfium 团队!)

如果你有旧版本，你只需要删除这些行

if (is_component_build || is_asan) {
  data_deps += [ "//build/android:cpplib_stripped" ]
}
