From 7ccdcaace80810175bd20b2ece856b42edd43991 Mon Sep 17 00:00:00 2001 From: Jisheng Zhang Date: Thu, 25 Mar 2021 12:06:01 +0800 Subject: [PATCH] tee: optee: fix build error caused by recent optee tracepoints feature If build kernel without "O=dir", below error will be seen: In file included from drivers/tee/optee/optee_trace.h:67, from drivers/tee/optee/call.c:18: ./include/trace/define_trace.h:95:42: fatal error: ./optee_trace.h: No such file or directory 95 | #include TRACE_INCLUDE(TRACE_INCLUDE_FILE) | ^ compilation terminated. Fix it by adding below line to Makefile: CFLAGS_call.o := -I$(src) Tested with and without "O=dir", both can build successfully.
