#10890

[Jimex]

#10890

Could you elaborate further? Should I consider adding any CMake parameters to the Android build to prevent this error?

Thank you.

[slaren]

I suspect that this is due to using /dev/null on Windows host, but regardless this should not be a fatal error. Can you test #10961?

[Jimex]

I tested the latest build, but unfortunately, the issue persists. Below is the CMake error log, where the fatal error appears to be: "error: unknown argument: '-mfp16-format=ieee'".

These messages are not indicative of a failed build, compiler tests are expected to fail occasionally.

[Jimex]

The compiler output still the same actually.

The compiler output still the same actually.

You need to clear the cmake cache

I tried cleaning the project and deleting all temporary build files, but it still didn’t work.

It only worked after replacing the ggml/src/ggml-cpu/CMakeLists.txt file with the version from b4357.

[Jimex]

The last build no more problems, thank you.
