Bug ID: 120496
Summary: adaint.h:324:8: error: unknown type name 'cpu_set_t'
Product: gcc
Version: 15.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: dclarke at blastwave dot org
CC: dkm at gcc dot gnu.org
Target Milestone: ---
This is fairly consistent and repeatable.
With Alpine Linux and MUSL LibC on a Raspberry Pi5 we may configure just
fine thus :
