Linker error unresolved external symbol simdjson::internal::error_code_info about simdjson HOT 2 CLOSED

It is OK when include the simdjson.h and simdjson.cpp into my project directly.

That's often simple. There is nothing wrong with it.

You can reproduct it by goto https://github.com/hongxinGuo/FireBird, download the branch vcpkg_simdjson_LNK2001_error.

We are supported by vcpkg. You can check the demonstration at https://github.com/simdjson/simdjson-vcpkg

You can test it out for yourself: CMake will generate a Visual Studio project which you can build.

The most likely explanation of your trouble is that you have a misconfiguration as part of your Visual Studio solution or with vcpkg. If you think that there is a problem with vcpkg and you have followed their instructions, then you should raise an issue with vcpkg.

If you think that there is a bug in simdjson, please provide an example of your issue using CMake, as this is the build system we directly support.

I am not a Visual Studio expert, but let us consider the build settings from your main branch:

Here are the new settings...

So, at a glance, you have removed entirely simdjson from your Visual Studio configuration.

That means that you must rely on Visual Studio integration with vcpkg. This requires some work. You have not provided details. If you have not done some, please review the appropriate documentation :
