From dc816e5d84cbc28baf776799839a632d6002236f Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Sun, 18 Jun 2017 09:56:03 +0900 Subject: selftest/intel_pstate/aperf: Use LDLIBS instead of LDFLAGS Build of aperf fails as below: ``` gcc -Wall -D_GNU_SOURCE -lm aperf.c -o /tools/testing/selftests/intel_pstate/aperf /tmp/ccKf3GF6.o: In function `main': aperf.c:(.text+0x278): undefined reference to `sqrt' collect2: error: ld returned 1 exit status ``` The faulure occurs because -lm was defined as LDFLAGS and implicit rule of make places LDFLAGS before source file. This commit fixes the problem by using LDLIBS instead of LDFLAGS.
