[skywalking-go]When I was using the Skywalk-go agent, I had a problem with not being able to build the project

[pinkfloyd-eminem]

U-VF4VY9W5-1944:skywalking-go-test whlongxi$ sudo go build -toolexec="./go-agent" -a
Password:
go: error obtaining buildID for go tool compile: fork/exec ./go-agent: permission denied

I referred to https://skywalking.apache.org/docs/skywalking-go/v0.2.0/en/setup/gobuild/。

how to solve this problem？

[wu-sheng]

This seems a basic Linux issue. Do you add sudo or grant execute to the file?

[pinkfloyd-eminem]

yes，I started with the absolute path of the agent, and then copied the agent into the project and used the relative path, which didn't work

[pinkfloyd-eminem]

Neither the absolute path nor the relative path.Is there any official image? The image contains the example of skywalk-go accessing demo

Is there any official image?

Here is an example using the skywalking-go docker image.

Also, have you checked your private access control on MacOS? they maybe need you to trust the download execute the file.

But I also tried in another Alibaba Cloud ecs environment and encountered the same problem.

[mrproliu]

I have tried it in the cloud and it works well. I'm not sure what's happened to you.
Have you tried to execute the agent program directly? Such as /path/to/skywalking-go-agent-0.2.0-linux-amd64 --help?
If you are unable to work properly, please make sure that the downloaded binary file is correct, the platform is correct, or if there are relevant permissions.

Thank you. I have successfully connected to Skywalk-go agent. Thank you for your help. My steps are as follows:
1.cd skywalking-go/
2.go build
3.sudo go build -toolexec "/path/to/skywalking-go/bin/skywalking-go-agent--darwin-amd64 -config /path/to/my_agent_config.yaml" -a （The path of the executable file is an absolute path）

It's another way to build the agent from the source, you could follow this documentation if needed.
