Why Does Makefile Throw a Permission Denied Error for Go Commands?

Permission Denied Error in Makefile When Running Go

You may encounter "permission denied" errors while running Go commands through a Makefile, even when you can execute them directly. This discrepancy arises due to an issue in GNU make.

Cause:

The error occurs when you have a directory on your PATH that contains a subdirectory named "go." For instance, if you have "/usr/bin/go/" on your PATH, it could interfere with the execution.

Solution:

To address this issue, check your PATH variable and remove any directories containing subdirectories named "go." If that's not feasible, add a semicolon (";") after the "go run" command in your Makefile to force GNU make to use a shell.

Example:

run:
    go run . ;

Additional Insights:

• Running "make with -d/--trace" shows that GNU make doesn't recognize "run" as a target due to a non-existent directory or file by that name.
• In the case of "run2," the echo command forces GNU make to interpret it as a target, allowing the "go run" command to execute successfully.
