This is now causing an autoremoval for armnn in Debian Testing:
"armnn 20.08-9 is marked for autoremoval from testing on 2021-10-25"
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=983969
Debian Testing/Bookworm will use GCC-11, Bullseye was GCC-10 https://packages.debian.org/sid/gcc-11
Hi @ggardet,
Does https://review.mlplatform.org/c/ml/armnn/+/6283 fix all of the above errors or do you still see this one? https://github.com/ARM-software/armnn/issues/548#issuecomment-881268218
I still get that one in Ubuntu Impish.
Regards, Francis.
@FrancisMurtagh-arm Here is the changelog:
- Add '-Wno-error=stringop-overread' to workaround build error
with GCC11 with openCL enabled
- Add '-Wno-error=uninitialized -Wno-error=array-bounds' to
workaround build issues with GCC11 - https://github.com/ARM-software/armnn/issues/548
Hi @ggardet,
Would you be able to attempt a build with the patch https://review.mlplatform.org/c/ml/armnn/+/6283 and without the -Wno-error flags just to see are all errors from 1 commit?
It could help us removing them warnings, as we're seeing conflicting results here, it doesn't occur in cross compile for example.
Regards, Francis.
Current version is 21.08, not 21.05 anymore. Would that be ok for you?
EDIT: also, I have multiple -Wno-error* flags accumulated. If you want to see all warnings/errors, you should use GCC11.
Hi @ggardet,
21.08 would be fine yes, I'm using Ubuntu Impish which is using GCC-11 too.
Thanks, Francis.
I added https://review.mlplatform.org/c/ml/armnn/+/6283 on top of 21.08 and removed all -Wno-error* flags.
Now, the errors I get are only when openCL is enabled.

Workaround: -Wno-error=stringop-overread
Hi @ggardet,
Thanks for confirming, that's the same result I am seeing in Ubuntu Impish.
Cheers, Francis.
Hi @ggardet,
This patch fixes the -Wno-error=stringop-overread based on the bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99578
https://review.mlplatform.org/c/ml/armnn/+/6504
Also I'm not sure -Wno-error=deprecated-declarations is required as I built successfully on Ubuntu Impish without it, it appears to be something to "note" rather than treat as a warning :thinking:
Thanks, Francis.
Indeed, -Wno-error=deprecated-declarations is not required as it is just a note. But the include path needs to be updated to be future proof.
Hi @ggardet,
I pushed a patch for the pragma: https://review.mlplatform.org/c/ml/armnn/+/6516
However would it be possible we are using teo different cl2.hpp files in our packaging?
I found references to the pragm here: https://github.com/KhronosGroup/OpenCL-CLHPP/blob/master/include/CL/cl2.hpp
Whereas the ACL cl2.hpp header doesn't look to have it. https://github.com/ARM-software/ComputeLibrary/blob/master/include/CL/cl2.hpp
Would the khronos header have been installed in your system includes from some other package?
Thanks, Francis.

You switch from CL/CL2.hpp to CL/opencl.h. I think it should be CL/opencl.hpp.

I indeed use opencl-headers/opencl-cpp-headers from the distribution, with -DOPENCL_INCLUDE=%{_includedir}.
Hi @ggardet,
Yes so the difference in name was what made me look into it a bit more. We build-depend on ComputeLibrary packaging whose include/CL folder looks like this:
https://github.com/ARM-software/ComputeLibrary/tree/master/include/CL
opencl.h
I had assumed openSuse had a similar package but the contents of the .rpm seem to be more like sampledata and for x86 https://software.opensuse.org/package/ComputeLibrary
I've asked ACL to see do they know more about the significance of the differing names.
Francis.
Clearly, ACL should not package those header files and should depend on opencl-headers package instead.
Latest packages for Arm can be found here: https://build.opensuse.org/package/binaries/openSUSE:Factory:ARM/ComputeLibrary/standard
*.h vs *.hpp are C vs C++ headers
Thanks, I realise they're c vs c++ more so the reason why ACL provides one over the other.
I see that debian also have those headers so we better look into it on our side: https://packages.debian.org/bullseye/all/opencl-clhpp-headers/filelist
Francis.
