Subject: [PATCH] perf build: Fix static build of dlfilters
Date: Mon, 13 Jul 2026 11:23:01 +0100	[thread overview]
Message-ID: <20260713-perf_fix_static_build-v1-1-460be1f9e4d6@arm.com> (raw)

Commit e1065ed188cf ("perf build: Add LDFLAGS to dlfilters .so link")
passes LDFLAGS when linking dlfilter shared objects. That breaks static
builds because LDFLAGS can contain -static, leading to an invalid link
command.

dlfilters are always built as shared objects, even for a static perf
binary. Filter out -static for the dlfilter .so link while preserving
the rest of LDFLAGS.

Fixes: e1065ed188cf ("perf build: Add LDFLAGS to dlfilters .so link")
