Why Am I Getting \'Permission Denied\' Errors When Running Go Programs Through a Makefile?

Permission Denied: Investigating the Difference Between 'go run' and Makefile Invoking

Encountering permission denied errors while running a Go program through a Makefile can be perplexing. This issue stems from a bug in GNU make or its gnulib component. The root cause lies in the presence of a directory named "go" in the system's PATH that precedes the directory where the actual Go executable resides.

To determine if this is the underlying cause, inspect your system's PATH and check for any directories that contain a subdirectory named "go." For instance, if /usr/bin/go/ exists and /usr/bin is part of your PATH, you may encounter this problem.

To rectify the situation, ensure that any directories containing "go" subdirectories are removed from your PATH. If this is not feasible, you can alternatively use a shell invocation for GNU make's execution. Adding the ; character to the Makefile target will suffice:

run:
        go run . ;
