iOS ARM64 only: undefined symbol: v8_Default_embedded_blob_code_

[Benoit Blanchon]

Hi,

I successfully build PDFium with V8 on most platforms, but I'm having the following linker errors when target_os=ios and target_cpu=arm64:

ld64.lld: error: undefined symbol: v8_Default_embedded_blob_code_
>>> referenced by isolate.cc:0 (../v8/src/execution/isolate.cc:0)

As far as I can tell, v8_Default_embedded_blob_data_ is defined in v8/src/builtins/arm64/builtins-arm64.cc, which seems to build fine (see log).

Any idea how I could fix this?

Best regards,

Benoit

Since your question is about building V8 on iOS, it will be best to
ask on a V8 mailing list.
