First, make sure you have necessary prereqs for building:
brew install automake libtool protobuf golang cmake
Take a nap while that completes. Then, build the protos:
cd firebase-ios-sdk # the root of this repo, not Firestore/Protos
mkdir -p build
cd build
cmake ..
make -j generate_protos
Verify diffs, make sure tests still pass, and create a PR.
- Modify version in nanopb.cmake.
- Build.
- Note build failure.
- Plug expected hash into nanopb.cmake.
Get the protoc and the gRPC plugin. See
here. The
easiest way I found was to add
pod '!ProtoCompiler-gRPCPlugin' to a Podfile and do pod update.
After running the protoc, shell commands run to fix up the generated code:
- Flatten import paths for CocoaPods library build.
- Remove unneeded extensionRegistry functions.
- Remove non-buildable code from Annotations.pbobjc.*.
