Question Subject

I am unable to generate swift grpc files due to an 'libswiftCore.dylib' error.

Question Description

Hello,

I installed the latest version of plugin grpc/grpc-swift today, and was trying to generate Swift & SwiftGRPC files based on .proto file I have.

When I run protoc command just with --swift_out & --swiftgrpc_out, I get the following error.

This copy of libswiftCore.dylib requires an OS version prior to 10.14.4.
--swiftgrpc_out: protoc-gen-swiftgrpc: Plugin killed by signal 6.

I am on macOS 10.15 Catalina Beta in order to develop using Xcode 11, and I have hit a roadblock because of this. If I wanted to check out versions... I get the similar error as well.

my-mbp:~/Dev/grpc-swift> protoc-gen-swift --version
This copy of libswiftCore.dylib requires an OS version prior to 10.14.4.
zsh: abort      protoc-gen-swift --version
my-mbp:~/Dev/grpc-swift> protoc-gen-swiftgrpc --version
This copy of libswiftCore.dylib requires an OS version prior to 10.14.4.
zsh: abort      protoc-gen-swiftgrpc --version
my-mbp:~/Dev/grpc-swift

The strange thing here is that, protoc-gen-swift binary generated from this repo does not work due to above error, but protoc-gen-swift binary installed from this repo's https://github.com/apple/swift-protobuf brew install works fine in my system. The latter protoc-gen-swift's version is 1.5.0 and it can generate swift files based on my proto file without an issue.

Is the latest version of grpc/grpc-swift not yet compatible with macOS 10.15?

How did you build the protoc plugin for Swift GRPC? On which OS version did you build that plugin?

cielo commented 5 years ago

For protoc binary, I downloaded version 3.8.0 from https://github.com/protocolbuffers/protobuf/releases.

For this 'SwiftGRPC' plugin, I built it in macOS 10.15 Beta 2 Catalina by running make plugin command. While building the plugin, it did generate few warning logs..

Thanks. Could you try removing the --static-swift-stdlib flags in the Makefile, run make plugin again, then see if that helps?

cielo commented 5 years ago

After removing the --static-swift-stdlib options from plugin target, if I run make clean; make plugin, build does not generate warnings related to statically linking the swift libraries anymore.

However, it still complains about libswiftCore.dylib.

Does this plugin change anything about apple/swift-protobuf.git's ./protoc-gen-swift? Apple one seems to work fine in my setup, but unfortunately, it does not contain gRPC specific service code gen so I have to rely on this repo.

Hey @cielo I'm facing the same issue. Did you manage to solve it?

aostiles commented 5 years ago

I had this issue and got them to work using the swift 5.1 command line tool. This post was key for me. I haven't actually tried building an iOS app yet, but compiling a proto file with protoc <my_proto_file> --swift_out=. --swiftgrpc_out=Client=true,Server=false:. seems to work. I'm using libprotoc 3.9.0, built protoc-gen-swift and protoc-gen-swiftgrpc from this repo (8eac348), and am running the Catalina beta (19A526h). swift reports (swiftlang-1100.0.266.1 clang-1100.0.32.1).
