[-- Attachment #1.1: Type: text/plain, Size: 3289 bytes --]

Hello,

I am trying to build a new Buildroot package for i.MX Neural Networks
Accelerator Plugin <https://github.com/nxp-imx/nn-imx/tree/imx_1.3.0> . The
imx-nn-accelerator.mk :
#############################################################
#
# i.MX Neural Networks Accelerator Plugin
#
#############################################################

IMX_NN_ACCELERATOR_VERSION = lf-5.15.71-2.2.1
IMX_NN_ACCELERATOR_SOURCE = $(IMX_NN_ACCELERATOR_VERSION).tar.gz
IMX_NN_ACCELERATOR_SITE =
https://github.com/nxp-imx/nn-imx/archive/refs/tags
IMX_NN_ACCELERATOR_LICENSE = MIT
IMX_NN_ACCELERATOR_LICENSE_FILES = LICENSE
IMX_NN_ACCELERATOR_DEPENDENCIES = imx-gpu-viv

PKG_NAME = imx-nn-accelerator
PKG_VERSION = lf-5.15.71-2.2.1

define IMX_NN_ACCELERATOR_BUILD_CMDS
    $(MAKE) LDFLAGS="$(TARGET_LDFLAGS)" -C $(@D) \
        SDKTARGETSYSROOT=$(STAGING_DIR) \
        AQROOT=$(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)
endef

define IMX_NN_ACCELERATOR_INSTALL_TARGET_CMDS
    $(INSTALL) -D -m 0644 $(@D)/libneuralnetworks*.so*

    $(INSTALL) -d -m 0755 $(TARGET_DIR)/usr/include/OVXLIB
    $(INSTALL) -d -m 0755 $(TARGET_DIR)/usr/include/nnrt
    cp -r $(@D)/include/OVXLIB/* $(TARGET_DIR)/usr/include/OVXLIB/
    cp -r $(@D)/include/nnrt/* $(TARGET_DIR)/usr/include/nnrt/
endef

$(eval $(generic-package))

This is already integrated in Yocto nn-imx_1.3.0.bb
<https://github.com/nxp-imx/meta-imx/blob/64a864ab77de06a557afcb01e6dd4d21606e6948/meta-ml/recipes-libraries/nn-imx/nn-imx_1.3.0.bb>
and I am trying to replicate the same in Buildroot. But while building this
is giving the error:

It looks like it is failing to link against the target architecture..
(LDFLAGS variable is empty)

Can anyone please let me know what is missing in makefile and how to
resolve this?

Thanks in advance

You're using the host linker here (/usr/bin/ld), which of course will
not work to link binaries for the target. Replace:

define IMX_NN_ACCELERATOR_BUILD_CMDS
    $(MAKE) LDFLAGS="$(TARGET_LDFLAGS)" -C $(@D) \
        SDKTARGETSYSROOT=$(STAGING_DIR) \
        AQROOT=$(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)
endef

By:

define IMX_NN_ACCELERATOR_BUILD_CMDS
    $(MAKE) $(TARGET_CONFIGURE_OPTS) -C $(@D) \
        SDKTARGETSYSROOT=$(STAGING_DIR) \
        AQROOT=$(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)
endef

TARGET_CONFIGURE_OPTS contains the definitions of CC, LD, CFLAGS,
LDFLAGS, and a whole bunch of other variables.

Also, AQROOT can use $(IMX_NN_ACCELERATOR_BUILD_DIR) directly.

[-- Attachment #1.1: Type: text/plain, Size: 8260 bytes --]

Hello Thomas,

Thanks for the update.

After changing the makefile to

define IMX_NN_ACCELERATOR_BUILD_CMDS
    $(MAKE) $(TARGET_CONFIGURE_OPTS) -C $(@D) \
        SDKTARGETSYSROOT=$(STAGING_DIR) \
        AQROOT= $(@D)
indeed

I am having below errors:

If those headers are part of the imx-nn-accelerator code, it probably
means that the fact we're passing CFLAGS="..." overrides some CFLAGS
defined by the package Makefile, while it should append to the CFLAGS
passed in the environment. Sometimes it requires tweaking the Makefile
of the package, sometimes it means CFLAGS need to be passed in the
environment of make (by Buildroot) instead of as argument:

	$(TARGET_MAKE_ENV) \
		$(TARGET_CONFIGURE_OPTS) \
		...
		$(MAKE) -C $(@D)

This really requires a package-specific investigation.

Best regards,

Thomas

This would be helpful.
