From bf71940fc16953bed84caa59b7b076ead70d42f6 Mon Sep 17 00:00:00 2001 From: David Engraf Date: Mon, 3 Feb 2025 08:36:10 +0100 Subject: [PATCH] objtool: Hide unnecessary compiler error message The check for using old libelf prints an error message when libelf.h is not available but does not abort. This may confuse so hide the compiler error message.
