Descrizione

What version of Go are you using (`go version`)?

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (`go env`)?

What did you do?

I tried to build a MacOS bundle using dynamically linked libraries. As per convention these are stored in MyApp.app/Contents/Frameworks which requires LC_RPATH to point there.

I added the following flag:

#cgo LDFLAGS: -Wl,-rpath,@executable_path/../Frameworks

What did you expect to see?

go build builds binary with LC_RPATH set to @executable_path/../Frameworks

What did you see instead?

I got an invalid flag error upon running go build.

I also tried replacing @executable_path for $ORIGIN as I would in Linux but then I got an image not found error when running the resulting binary (I assume this isn't supported on MacOS).

Guida contributor

Direzione di ricerca: Indaga perché lo strumento go rifiuta `@executable path` in LDFLAGS. Esamina la convalida di LDFLAGS nel codice sorgente dello strumento go, in particolare attorno a CGO e all'analisi dei flag. Considera come `@executable path` viene gestito su macOS e se esiste una whitelist o una convalida che lo vieta.
