I tried to do the following:
clang++ -std=c++11 -stdlib=libc++ -Weverything -I.
out/x64.release/libv8_base.a out/x64.release/libv8_libbase.a
out/x64.release/libv8_nosnapshot.a out/x64.release/libicudata.a
out/x64.release/libicuuc.a out/x64.release/libicui18n.a hello_world.cpp -o
hello_world
Which gives me:
99 warnings generated.
Undefined symbols for architecture x86_64:
"v8::platform::CreateDefaultPlatform(int)", referenced from:
_main in hello_world-0e9dbc.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
So I guess I'm still no closer to get this to work.
