[v8-users] v8 Android link error()
I build v8 static libraries for android successfully(using V8 6.5), and
then embed it in andoid app(using the hello-world.cc demo from official
wiki. Android studio 3.1,Cmake),but error like the follow takes place
while building the APK
Build command failed.
Error while executing process

../../src/isolate.cc:0: error: undefined reference to 'vtable for
v8::internal::SetupIsolateDelegate'
/usr/local/v8/v8/third_party/android_ndk/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/../../../../arm-linux-androideabi/bin/ld:
the vtable symbol may be undefined because the class is missing its key
function
clang++: error: linker command failed with exit code 1 (use -v to see
invocation)
ninja: build stopped: subcommand failed.
the key point is " 'vtable for v8::internal::SetupIsolateDelegate'",is
the libv8_base.a not correct?
Any help is appreciated!
