ort-qnn: Build onnxruntime QNN Execution Provider plugin v2.4.0 by pratikpachange97 · Pull Request #2837 · qualcomm-linux/meta-qcom

pratikpachange97 · 2026-07-29T10:42:16Z

QNN EP is a standalone ABI-stable plugin execution provider that brings Qualcomm hardware acceleration to ONNX Runtime. Starting with v2.0.0, the QNN EP ships as a standalone shared library built on the Execution Provider ABI. The plugin is registered at runtime and only links against the standard ONNX Runtime shared library.
Added collection name "ai" and corresponding filename pattern and layer.conf for this recipe file as it depends on meta-ai layer.

+CFLAGS:append   = " -ffile-prefix-map=${WORKDIR}=. -ffile-prefix-map=${S}=. -ffile-prefix-map=${B}=."
+CXXFLAGS:append = " -ffile-prefix-map=${WORKDIR}=. -ffile-prefix-map=${S}=. -ffile-prefix-map=${B}=."


I think these are already set via DEBUG_PREFIX_MAP. Are OECMAKE flags being overridden by the project?

DEBUG_PREFIX_MAP is set as follows

DEBUG_PREFIX_MAP="-fcanon-prefix-map -ffile-prefix-map=/local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0/sources/onnxruntime-qnn-2.4.0=/usr/src/debug/onnxruntime-qnn/2.4.0 -ffile-prefix-map=/local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0/build=/usr/src/debug/onnxruntime-qnn/2.4.0 -ffile-prefix-map=/local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0/recipe-sysroot= -ffile-prefix-map=/local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0/recipe-sysroot-native= "

Here -ffile-prefix-map=${WORKDIR}=. is missing in the DEBUG_PREFIX_MAP

If I remove these flags I am getting following error
ERROR: onnxruntime-qnn-2.4.0-r0 do_package_qa: QA Issue: File /usr/lib/.debug/libonnxruntime_providers_qnn.so in package onnxruntime-qnn-dbg contains referenc
e to TMPDIR [buildpaths]

Following flags are required to resolve this error

CFLAGS:append = " -ffile-prefix-map=${WORKDIR}=." CXXFLAGS:append = " -ffile-prefix-map=${WORKDIR}=."

Should I update these flags as above ?

What is not being handled? Which paths are left uncovered by OE classes?

-ffile-prefix-map=/local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0=.

What is the path embedded in binary? WORKDIR in this case is /local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0 so unless the path embedded is specifically only WORKDIR, which is unlikely, it should already be covered.

Usually, it's a problem when the project is overriding these flags passed by OE. In this case, it might be overriding CMAKE_C*_FLAGS.

The project is not overriding the flags
It seems the issue is due the git://github.com/dcleblanc/SafeInt.git source fetched to ${WORKDIR}/sources/safeint

The libonnxruntime_providers_qnn.so extracted from onnxruntime-qnn-dbg-2.4.0-r0.cortexa53.rpm has DWARF directory-table entry ./sources/safeint

OE's built-in DEBUG_PREFIX_MAP only remaps ${S} and ${B}
DEBUG_PREFIX_MAP="-fcanon-prefix-map -ffile-prefix-map=/local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0/sources/onnxruntime-qnn-2.4.0=/usr/src/debug/onnxruntime-qnn/2.4.0 -ffile-prefix-map=/local/mnt/workspace/mainline/build/tmp/work/cortexa53-qcom-linux/onnxruntime-qnn/2.4.0/build=/usr/src/debug/onnxruntime-qnn/2.4.0

It has no entry for ${WORKDIR}/sources/safeint.

So I guess adding

CFLAGS:append = " -ffile-prefix-map=${WORKDIR}=." CXXFLAGS:append = " -ffile-prefix-map=${WORKDIR}=."

is helping to fix this QA failure

Thank you for checking. In that case, I think adding this would resolve this:

I checked this in my local build as well and it works for me.

This is very close to the onnxruntime recipe in meta-ai and it seems to need the same fixes. Looks good enough to me.

Even without the change, looks good to me.
