The definition of ALIGN used in perf takes 2 parameters: ALIGN(x,a). This leads to redefinition conflicts. Redefinition error on Android: In file included from util/include/linux/list.h:1:0, from util/callchain.h:5, from util/hist.h:6, from util/session.h:4, from util/build-id.h:4, from util/annotate.c:11: util/include/linux/kernel.h:11:0: error: "ALIGN" redefined [-Werror] bionic/libc/include/sys/param.h:38:0: note: this is the location of the previous definition Conflics with system defined ALIGN in Android: util/event.c: In function 'perf_event__synthesize_comm': util/event.c:115:32: error: macro "ALIGN" passed 2 arguments, but takes just 1 util/event.c:115:9: error: 'ALIGN' undeclared (first use in this function) util/event.c:115:9: note: each undeclared identifier is reported only once for each function it appears in In order to avoid this redefinition, ALIGN is renamed to PERF_ALIGN.
