Build Error with CONFIG_ACL_GPU=y in RasbperryPi3 B about tengine

[ghimiredhikura]

Possible solution: build tengine driver without -Werror option.

It seems that those build error are due to -Werror (warning error) option in tengine driver Makefile.
Therefore I rebuild tengine without -Werror option, and build was successful.

driver-$(CONFIG_CAFFE_REF)+=caffe/
driver-$(CONFIG_ACL_GPU)+=acl_graph/
driver-$(CONFIG_ACL_GPU)+=acl/

obj-y+=cpu/ plugin/  $(driver-y)


INC_DIR+=-I$(shell pwd)/include 
INC_DIR+=-I$(shell pwd)/../include 
INC_DIR+=-I$(shell pwd)/../core/include
INC_DIR+=-I$(shell pwd)/../operator/include 
INC_DIR+=-I$(shell pwd)/../executor/include 

CXXFLAGS+=

COMMON_CFLAGS+=$(CONFIG_OPT_CFLAGS)
#COMMON_CFLAGS+= -Wall -g -fPIC  $(INC_DIR) -Werror
COMMON_CFLAGS+= -Wall -g -fPIC  $(INC_DIR)

ifeq ($(CONFIG_CAFFE_REF),y)
    COMMON_CFLAGS+= -DCONFIG_CAFFE_REF=1
endif

ifeq ($(CONFIG_ARCH_ARM64),y)
    COMMON_CFLAGS+= -DCONFIG_ARCH_ARM64=1
endif

ifeq ($(CONFIG_ACL_GPU),y)
    COMMON_CFLAGS+= -DCONFIG_ACL_GPU=1
endif

ifeq ($(CONFIG_ARCH_ARM32),y)
    COMMON_CFLAGS+= -DCONFIG_ARCH_ARM32=1
endif

install:

but got cl::Error in runtime

$ ./build/tests/bin/bench_sqz -d acl_opencl

Output

pi@raspberrypi:~/Desktop/project/tengine $ ./build/tests/bin/bench_sqz -d acl_opencl
terminate called after throwing an instance of 'cl::Error'

Just a double check, do you use the Arm Compute library v18.05?

Thanks,

[ghimiredhikura]

Yes I used v18.05 version. And I used openblas library.
It will be nice, if you can check in Pi3 device.
Btw, is there any plan to support neon instructions from ACL library. I think currently it only supports opencl from ACL.

Thanks,
