Hi all,
I use SDK 8.4 and TDA4 platform.
I create a new a application (app_pthread_create) under vision_apps/apps/basic_demos directory.
My concerto.mak
ifeq ($(TARGET_CPU), $(filter $(TARGET_CPU), x86_64 A72)) include $(PRELUDE) CPPSOURCES := pthread_create.cpp TARGET := vx_app_pthread_create TARGETTYPE := exe ifeq ($(TARGET_CPU),x86_64) CSOURCES += main_x86.c include $(VISION_APPS_PATH)/apps/concerto_x86_64_inc.mak STATIC_LIBS += $(IMAGING_LIBS) endif ifeq ($(TARGET_CPU),A72) ifeq ($(TARGET_OS), $(filter $(TARGET_OS), LINUX QNX)) include $(VISION_APPS_PATH)/apps/concerto_a72_inc.mak STATIC_LIBS += $(IMAGING_LIBS) endif endif ifeq ($(TARGET_CPU),A72) ifeq ($(TARGET_OS),SYSBIOS) TARGETTYPE := library include $(VISION_APPS_PATH)/apps/concerto_a72_inc.mak endif endif IDIRS += $(IMAGING_IDIRS) #LIBS += -lpthread LDFLAGS += -lpthread include $(FINALE) endif
My source code pthread_create.cpp
I got following error message.

How can I fix the problem?
Could you give me suggestion?
