Video Sdk Electron demo x64 links error with abseil on windows

Video SDK

Hi, I tried the Zoom Video SDK electron demo these days following the official guidance.

After configuring everything mentioned in the guidance, I just ran npm run electron:serve, it is all ok on Mac, but fails on Windows .

I got these link errors

It sounds like that the protobuf lib missed some symbols’ implementation. I found nothing in bindings.gyp showing linkage with abseil. Was it linked by protobuf.lib?

I would be extremely grateful if someone could give a clue.

Well, I figured out the problem eventually. The protobuf-lite.lib was statically linked with the abseil-cpp with the ABSL_OPTION_INLINE_NAMESPACE_NAME settings to lts_20230802. Symbols in protobuf-lite.lib were under namespace lts_20230802. However, this namespace was not mentioned in the guidance, and the default namespace was used. So when linkage the default namespace symbols were required. To fix it, just change the namespace in Sample/lib/node_add_on/protobuf_src/absl/base/options.h as below.

-#define ABSL_OPTION_USE_INLINE_NAMESPACE 0
-#define ABSL_OPTION_INLINE_NAMESPACE_NAME head
+#define ABSL_OPTION_USE_INLINE_NAMESPACE 1
+#define ABSL_OPTION_INLINE_NAMESPACE_NAME lts_20230802

Or you can compile another protobuf-lite.lib with the default namespace.
