grpc-java build failure

[joseph....@gmail.com]

While attempting to build/install grpc-java I ran into the following failure:

It appears that something in Google Protobuf is missing. What needs to be done to resolve this? Why is it "missing"?

[chengyu...@google.com]

Please follow instructions here to build the codegen plugin before building grpc-java

[joseph....@gmail.com]

I have reviewed the instructions and immediately note that this is intended to be done on a *nix platform. I am running in Windows 10. How would I go about building this on that platform?

[chengyu...@google.com]

This should also work for Windows. There are sections (for Visual C++ and MinGW) about special notes for Windows users in that compiling guide.

[Eric Anderson]

Most users have no need to compile/build grpc-java directly. The document linked to earlier states at the beginning: "Building is only necessary if you are making changes to gRPC-Java or testing/using a non-released version (e.g. master HEAD) of gRPC-Java library."

We have pre-built binaries for the java code and protoc on Maven Central. We have made sure there are protoc plugins for Maven and Gradle to make using grpc easy.

So to start, you either:

1. Follow the README to add gRPC to a project you've already made

2. Follow the tutorials which have pre-built project, complete with Maven and Gradle configuration

In neither case do you need to compile protoc or grpc-java itself. It's important when using the tutorials to download a release and not master. The tutorials instruct you to clone at a particular release, but it sounds like you downloaded it manually. Downloading a .zip from the release page would work fine; download the zip, extract it, change directory to grpc-java-1.20.0/examples, and then continue with the tutorial.

If you want/need to build grpc itself, the COMPILING.md referenced earlier does describe how. Look for mentions of MinGW and Visual C++, depending on which way you want to build on Windows 10. I think we are using VS 2015 for our official release.

Oh, also. Commonly you don't need to compile protoc even when building grpc itself. See the mention of skipCodegen=true in COMPILING.md.
