Hello Ramesh, There might be a bit of confusion going on here. You are building V8 using `is_component_build = true` but would like to use `v8_libplatform.lib` as a static library. Note that V8 can be built either in component or in non-component mode but not in both modes.
IIUC the error comes from a component that tries to use libplatform built in component mode. It seems that you forgot to add v8_libplatform.lib to the linker input.
