The error no such package ‘google/protobuf’ occurs in bazel test genc/

[muramat21]

I could not do bazel test for genc and got an error.

I did the following steps as https://github.com/google/genc/blob/master/SETUP.md

git clone https://github.com/google/genc
cd genc
docker build -t genc .
docker run -it -v $PWD:/genc genc:latest /bin/bash -c "cd genc; /bin/bash"

Inside the running docker container instance, at the root of the repo, run:

bazel test genc/...

The error is:

ERROR: /genc/genc/python/base/BUILD:72:11: no such package 'google/protobuf': BUILD file not found in any of the following directories. Add a BUILD file to a directory to mark it as a package.

Protobuf, an external dependency library of genc, seems to be missing.

/genc/google/protobuf directory is still not created after running the bazel test

But there is /root/.cache/bazel/_bazel_root/715d91338ce19255fccde512098e4d79/external/com_google_protobuf

How can I make it work?

My environment is OS : Ubuntu 22.04.5 LTS Docker : 26.1.3

Is there an update on this issue? I am also getting the same.

I have solved the issue.
The reason of the error is that google3 is a library used within google, so the dependency cannot be resolved.
Install protobuf with pip and comment out the following in genc/python/base/BUILD

genc/genc/python/base/BUILD

Lines 81 to 82 in 518aa71

	"//google/protobuf:any_py_pb2",
	"//net/proto2/python/public",

Then change genc/python/base/to_from_value_proto.py as follows .

genc/genc/python/base/to_from_value_proto.py

Lines 16 to 17 in 518aa71

	from google3.google.protobuf import any_pb2
	from google3.net.proto2.python.public import message

from google.protobuf import any_pb2
from google.protobuf import message

It should work.
