How Can I Remove File Paths from Go Binaries Using `-trimpath`?

Removing File Paths from TEXT Directives in Go Binaries

To eliminate path information from the executable created by go build, use -trimpath flags.

Use -trimpath Flags:

Append -gcflags=-trimpath=/Users/myuser/dev/go/src and -asmflags=-trimpath=/Users/myuser/dev/go/src to the go build command:

CGO_ENABLED=0 go build -v -a -ldflags="-w -s" \
-gcflags=-trimpath=/Users/myuser/dev/go/src \
-asmflags=-trimpath=/Users/myuser/dev/go/src \
-o ./fooapi spikes/mongoapi.go

Explanation:

Passing -trimpath removes the prefix provided from recorded source file paths. This action eliminates path information from elf binaries.

Verification:

Use go tool objdump to confirm the removal:

$ go tool objdump ./fooapi
.
.
TEXT main.init(SB) api/spikes/mongoapi.go

Caution Regarding strip:

Although strip has been reportedly fixed, some controversies remain within the Go community. Unknown and unpredictable bugs may still occur. Exercise caution when using strip.
