Error of clang-14: error: linker command failed with exit code 1 (use -v to see invocation) in macOS

[elsagong]

I tried to run a demo of [pulsar-client-go](https://github.com/apache/pulsar-client-go) on macOS, but I always get the error of # github.com/99designs/go-keychain ld: framework not found CoreFoundation clang-14: error: linker command failed with exit code 1 (use -v to see invocation),

after I
export CGO_CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk" on console,
I got error as below
`# runtime/cgo

the code can run successfully in Linux, Does pulsar-client-go not work on MacOS?
Xcode 14.2
macOS 12.6.6

Thanks so much for any feedback.

Which demo did you run? Can you provide the details of reproduce steps?

Hi, I pasted demo as below, please check @tisonkun ```go package main import ( "fmt" "log" "time" "github.com/apache/pulsar/pulsar-client-go/pulsar" ) func main() { // Pulsar服务的URL pulsarURL := "pulsar://localhost:6650" // 创建Pulsar客户端 client, err := pulsar.NewClient(pulsar.ClientOptions{ URL: pulsarURL, }) if err != nil { log.Fatal(err) } defer client.Close() // 创建Pulsar生产者 producer, err := client.CreateProducer(pulsar.ProducerOptions{ Topic: "my-topic", }) if err != nil { log.Fatal(err) } defer producer.Close() // 发布消息 msg := &pulsar.ProducerMessage{ Payload: []byte("Hello, Pulsar!"), } _, err = producer.Send(msg) if err != nil { log.Fatal(err) } // 创建Pulsar消费者 consumer, err := client.Subscribe(pulsar.ConsumerOptions{ Topic:            "my-topic", SubscriptionName: "my-subscription", Type:             pulsar.Exclusive, }) if err != nil { log.Fatal(err) } defer consumer.Close() // 接收和处理消息 for { msg, err := consumer.Receive() if err != nil { log.Fatal(err) } fmt.Printf("Received message: %s\n", string(msg.Payload())) consumer.Ack(msg) } // 停止Pulsar消费者 consumer.Close() } ```

@tisonkun And after I export CGO_CFLAGS="-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk" on console, I got error as below
# runtime/cgo ld: library not found for -lpthread clang-14: error: linker command failed with exit code 1 (use -v to see invocation)
