最新v8Gyp编译已废弃，只支持GN编译。官网编译文档：

args.gn

is_debug = falsetarget_cpu = "arm"v8_target_cpu = "arm"target_os = "android"is_component_build = falsev8_static_library = truev8_enable_i18n_support = falsev8_use_snapshot = false

编译成功后out.gn/xxx/obj/下存在libv8_base.a等静态库。
使用时发现缺少libv8_libplatform.a

连接libv8_libplatform.a

GN的配置我们不用去管，更改现有工程就行。
打开obj/v8_hello_world.ninja,关键连接代码

obj/v8_libbase/bits.o obj/v8_libbase/cpu.o obj/v8_libbase/stack_trace.o obj/v8_libbase/division-by-constant.o obj/v8_libbase/file-utils.o obj/v8_libbase/functional.o obj/v8_libbase/ieee754.o obj/v8_libbase/logging.o obj/v8_libbase/once.o obj/v8_libbase/condition-variable.o obj/v8_libbase/mutex.o obj/v8_libbase/semaphore.o obj/v8_libbase/time.o obj/v8_libbase/sys-info.o obj/v8_libbase/random-number-generator.o obj/v8_libbase/platform-posix.o obj/v8_libbase/stack_trace_android.o obj/v8_libbase/platform-linux.o obj/v8_libplatform/default-platform.o obj/v8_libplatform/task-queue.o obj/v8_libplatform/trace-buffer.o obj/v8_libplatform/trace-config.o obj/v8_libplatform/trace-object.o obj/v8_libplatform/trace-writer.o obj/v8_libplatform/tracing-controller.o obj/v8_libplatform/worker-thread.o

这里的.o文件就是对应libv8_libplatform.a

编辑obj/v8_libsampler.ninja
alink obj/v8_libsampler/sampler.o 后添加上面.o文件。
删除libv8_libsampler.a重新运行ninja -C out.gn/arm.release
生成新的libv8_libsampler.a重命名为libv8_libplatform.a

libv8_base.a
libv8_libplatform.a
libv8_nosnapshot.a

libv8_snapshot.a为Android arm 静态库
