wasm-ld: error: /sdk/libprotobuf.a(common.o): undefined symbol

[GOVYANSONG]

While searching for solution, I stumbled upon another sample project: https://github.com/salrashid123/envoy_wasm. this one offers better clarity around envoy wasm bazel build. I was able to build and run the sample wasm without any issue. I will attempt to build the wasm in my original post and update status.

I was able to adapt my original sample project to utilize envoy wasm bazel build. bazel BUILD file attached herein for reference:

load("@bazel_skylib//lib:selects.bzl", "selects")
load(
"//bazel:envoy_build_system.bzl",
"envoy_package",
)
load("//bazel/wasm:wasm.bzl", "envoy_wasm_cc_binary")
load("@io_bazel_rules_go//proto:def.bzl", "go_proto_library")
