sorry,my English isnt well,so I try to descript the problem I had Describe the bug After read the Readme, I can generate throuth the first way Manual Generation with command protoc --rust_out=. --grpc_out=. --plugin=protoc-gen-grpc=which grpc_rust_plugin example.proto. bug when I try to generate proto file by protoc-grpcio.cargo build fail failed to execute command: Permission denied (os error 13). and the trace show that it panic at

        if self.always_configure || !build.join("CMakeCache.txt").exists() {
            run(cmd.env("CMAKE_PREFIX_PATH", cmake_prefix_path), "cmake");
        } else {
            println!("CMake project was already configured. Skipping configuration step.");
        }

fn run(cmd: &mut Command, program: &str) {
    println!("running: {:?}", cmd);
    let status = match cmd.status() {
        Ok(status) => status,
        Err(ref e) if e.kind() == ErrorKind::NotFound => {
            fail(&format!("failed to execute command: {}\nis `{}` not installed?",
                          e, program));
        }
        Err(e) => fail(&format!("failed to execute command: {}", e)),
    };
    if !status.success() {
        fail(&format!("command did not execute successfully, got: {}", status));
    }
}

To Reproduce Steps to reproduce the behavior:

1. clone the project protoc-grpcio
2. run the command cargo run --manifest-path example/Cargo.toml --bin server

Expected behavior build fail and panic thread 'main' panicked at ' failed to execute command: Permission denied (os error 13)

Could you please provide your example.proto file?

Could you please provide your example.proto file?

syntax = "proto3";

package example;

service Diner {
  rpc Eat(Order) returns (Check) {}
}

enum Item {
  SPAM = 0;
  EGGS = 1;
  HAM = 2;
}

message Order {
  repeated Item items = 1;
}

message Check {
  double total = 1;
}

It is the example proto of the project proto-grpcio . ice juju...

事实上让我很困惑的是,一开始用的是命令行,是能够生成对应的文件的.后来下了protoc-grpcio后,他的demo无法运行-. - .后面还试了试grpc-rust.也是可以自动生成相关文件的. 下面这是完整的报错信息

I cannot reproduce the error under this environment:

• Ubuntu 18.04
• GNU ld (GNU Binutils for Ubuntu) 2.30
• gcc version 7.3.0 (Ubuntu 7.3.0-27ubuntu1~18.04)
• libprotoc 3.1.0 (yes, I guess this is the cause, could you please try downgrading your protoc version?)
• cmake version 3.10.2

When I run the example I get:

好的,我试试换个版本的proto=. =

it dosent work yet.. now libprotoc version is 3.1.0

[LyunKi]

besides , the module build failed is ' failed to run custom build command for grpcio-sys v0.4.2 '.and when i google it , i found a problem likes mine ,and grpc-rs is mentioned. failed to run custom build command for `grpcio-sys v0.1.1

[ice1000]

The panicking code is actually:

https://github.com/pingcap/grpc-rs/blob/f1216de3605e14d47067f8e1a2a74878240b7339/grpc-sys/build.rs#L98

which is a cmake error.

[ice1000]

@Lynss Could you please provide your full log of cargo clean && cargo build? And please do enable verbose output, thanks.

[LyunKi]

it seems my fault... cause when I had to try to use the tower-grpc,the same error happened with 'permission denied'.

[ice1000]

This is a really weird environment. I'm quite curious about what on earth is causing you permission denied. Have you tried building it in another bash env? Like the Ubuntu builtin terminal, instead of CLion/IntelliJ's terminal?

[LyunKi]

Clion's teminal had been set into oh_my_zsh...
