From d7e05ceaa93417f6f0077444eb111f64df823d25 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 16 Oct 2017 15:53:08 -0300 Subject: [PATCH] perf tools: Do not check ABI headers in a detached tarball build When we use one of: [acme@jouet linux]$ make help | grep perf perf-tar-src-pkg - Build perf-4.14.0-rc3.tar source tarball perf-targz-src-pkg - Build perf-4.14.0-rc3.tar.gz source tarball perf-tarbz2-src-pkg - Build perf-4.14.0-rc3.tar.bz2 source tarball perf-tarxz-src-pkg - Build perf-4.14.0-rc3.tar.xz source tarball [acme@jouet linux]$ I.e. when we create a detached tarball to build perf outside outside the enveloping kernel sources (from a kernel tarball or a checked out linux.git directory) we by definition can't check for differences among the tools/{include,arch}, etc files we originally copied from the kernel, so bail out in that case, to avoid warnings when doing the detached builds.
