• Important notice:

Upstream recommends a minimum of 32GB of RAM for building.

If you get the error "c++: fatal error: Killed signal terminated program cc1plus", upstream recommends to decrease the number of building threads. You will need to manually modify the PKGBUILD for this, and add a '--parallel <n>' option at the end of the cmake build command.

@dbermond thank you, it works!

@StratosL implemented. This cmake option is also used in the openvino package, which is the base source used for building, so it makes a good addition. Also added the clang format cmake option.

Hi there, I bumped into the bug mentioned below, as explained here: https://pastebin.com/rUkGtWQA

Could you please take a look at the proposed patch? https://pastebin.com/AxJvf8Jd

Thanks, Stratos

I also have the NCC styling error preventing compilation:

/home/lukken/.cache/yay/intel-npu-compiler/src/openvino/src/common/util/include//openvino/util/variant_visitor.hpp:14:1: "<deduction guide for VariantVisitor>(Ts...)" does not match "^(operator.+|[\w]+|SoPtr.+|Impl<.*>)$" associated with FunctionTemplate

The package is building fine for me. I cannot reproduce any build issues.

Quick fix for deduction guide build error:

The package currently fails to build due to ncc naming style checker not supporting C++17 deduction guides.

Temporary fix: Add -DENABLE_NCC_STYLE:BOOL='false' to the cmake flags in build() function. This disables the development-only style checker and allows the build to complete successfully.

Got the following error building the package

Until the dev fixes it with a explicit regex capable but i've tried so many and they all failed so I used the magic wildcard, edit "src/openvino/cmake/developer_package/ncc_naming_style/openvino.style" FunctionTemplate: '^.*$' << this will accept anything. It will build successfully after that change, it does require abit of system resources, but I modified the PKGBUILD with --parallel 8, even though I have 22 cores, still takes 1+hr to build.

Error: "<deduction guide for VariantVisitor>(Ts...)" does not match "^(operator.+|[\w]+|SoPtr.+|Impl<.*>)$" associated with FunctionTemplate'

I think "<deduction guide for VariantVisitor>" is coming from further up the build chain, maybe a script, or config file included, that isn't escaped properly.

Does anyone know how to resolve?
