Could not build v8 on windows with VS2019

Hi for a few days I’ve been trying to build v8 on windows with MSVC 14.29.30133 and WinSDK 10.0.19041.0

My build commands:

python3 tools/dev/v8gen.py x64.release.sample
ninja -C out.gn/x64.release.sample v8_monolith

it produces this error

FAILED: obj/v8_base_without_compiler/api.obj

ninja: build stopped: subcommand failed.

I tried added -Winvalid-offsetof to cflags and also to toolchain.ninja, but with no luck.

Can sombody please help me ?

No. If you go with the MSVC, it should be 100+MB. Please refer to this dockerfile for the complete steps.

So the only question remains if the v8_monolith library should be around 1GB @caoccao Thanks fror the help
