Hello. I have been trying to upgrade my code from V8 v7.1 to 7.8. I'm using V8 version 7.8.279, which I'm picking from git branch 7.8.279 (please tell me if this is the wrong way to do it!).
I'm using v8gen.py to perform the build, and passing these arguments (via v8gen) to "gn" treat_warnings_as_errors=false is_component_build=true v8_enable_i18n_support=false v8_use_snapshot=true I invoke ninja as follows. I cite specific targets here, because one of the testing-related targets fails to build on my system. ninja -C out.gn/x64.release v8 v8_libbase v8_libplatform >From this build, I get '.lib' and '.dll' files as expected, and I dynamic link my own code to V8 using the lib files: "v8.dll.lib" "v8_libbase.dll.lib" "v8_libplatform.dll.lib". I've updated all of my code to conform with the API changes between V8 7.1 and V8 7.8. During linking, I get the following errors below. I note that this all works fine on V8 7.1, but I tried 7.6, and 7.7 with very similar results. I would appreciate any advice. Thanks a bunch!
