Hi,
As of now C API is not officially supported on arm. But there are plans to make it fully work on all supported platforms in KFR 6 that will be released soon.

Hi, As of now C API is not officially supported on arm. But there are plans to make it fully work on all supported platforms in KFR 6 that will be released soon.

Thank you for clarification.
I was misled by this phrase in the changelog:
"Allow C API to be built on non-x86 systems".

I'm really looking forward to this opportunity.

[XzuluX]

@dancazarin Is there already a specific schedule for when KFR 6 will be released? I would also like to use the C API on aarch64.

[dancazarin]

KFR 6 prerelease is planned for release in late December/early January. There is a possibility that this feature will be backported to KFR 5.x, then it will be released in coming days.

[XzuluX]

Thank you for the quick response, that sounds promising, and it would be nice if the C API could be compiled on ARM soon.

[dancazarin]

@XzuluX @dubrsl KFR6 preview has been pushed to a separate branch v6. See more #196 (comment)

[XzuluX]

@dancazarin Great, thank's for for the notification!

[dancazarin]

Note: on linux/macOS KFR C API requires passing -DCMAKE_POSITION_INDEPENDENT_CODE=ON to cmake.

[dancazarin]

KFR6 features are now available in main branch. ARM64 support for C API is added too. See documentation for more details.
