helloworld bazel build error on windows

[siddhesh]

Hello group,

I am a new member of this group. Just joined today. Looking forward to learning more about using bazel to build grpc c++ applications. I am working on a windows machine. 

I started with the helloworld tutorial explained on the grpc.io website. I've attached my files to this conversation. My folder contains the basic greeter client and server files along with the helloworld.proto file. I am struggling with getting the correct WORKSPACE and BUILD files. My current files are also in the attachment. Any help / suggestions are highly appreciated.

Here's the error message on running "bazel build :greeter_server" in the vs code powershell terminal:

----------------------------------------------------------------------------------------------------------------------------------------

Thank you in advance.

Apologies. Forgot to provide the attachment.

Hi siddhesh,

The archive you attached misses the BUILD file and without it I cannot try it. 

In the past I noticed that gRPC default hello_world example is more complex than necessary and the following example is easier to follow: https://pencilflip.medium.com/getting-started-with-grpc-and-bazel-24725fd9e5c2

Hi Konstantin, sorry about that. And thank you for taking the time to look into the issue. I've attached a new zip folder with all the necessary files. Will also try out the instructions in the link you sent. 

Regards,

Siddhesh

Siddhesh, I have updated your WORKSPACE file and now it compiles for me.

For some reason this group software does not allow me to attach the file, so I published it for you here: https://gist.github.com/konste/5ac691c8c5b094b4749a7b68b1066d91
