I'm trying to build V8 for embedding its dll files on my win32 C++ application. The build was successful with build command right below. However, when I try to link v8 and its dependency dll files with my test c++ project(Visual Studio 2019, Windows 10), link error occurs all the time.

* working

call gn gen --ide=vs2019 out.gn/x86.release --args="is_clang=true is_debug=false use_glib=false is_component_build=true v8_use_external_startup_data=true v8_static_library=false v8_enable_i18n_support=false target_cpu=\"x86\""

call ninja.exe -C out.gn/x86.release v8.dll.lib

So I changed one of build options(is_clang=true to false) to link successfully, and now build process failed with this error

"FAILED: obj/build/config/sanitizers/options_sources.lib

* not working

call gn gen --ide=vs2019 out.gn/x86.release --args="is_clang=false is_debug=false use_glib=false is_component_build=true v8_use_external_startup_data=true v8_static_library=false v8_enable_i18n_support=false target_cpu=\"x86\""

call ninja.exe -C out.gn/x86.release v8.dll.lib

Any idea to solve this issue?

By installing a python package it has been solved. python -m pip install pywin32

I just make visual studio solution file by 'call gn gen --ide=vs2019 out.gn/x86.release --args="is_clang=false is_debug=false use_glib=false is_component_build=true v8_use_external_startup_data=true v8_static_library=false v8_enable_i18n_support=false target_cpu=\"x86\""'

On visual studio I try to build whole solution, but too many link error occurs. I don't know why it happens.
