Original Pull Request: https://github.com/ollama/ollama/pull/11908

State: closed
Merged: Yes

It looks like our almalinux-8 base doesn't have this macro defined in the headers we're including.

This includes sys/auxv.h, which includes bits/hwcap.h. On our base image, that header states:

/* The following must match the kernel's <asm/hwcap.h>.  */
#define HWCAP_FP                (1 << 0)
#define HWCAP_ASIMD             (1 << 1)
...

and does NOT include HWCAP2_SVE2, however, looking at asm/hwcap.h the macro is defined as

#define HWCAP2_SVE2             (1 << 1)

Confirmed with this patch our docker build works
