Hello,
For future reference what it takes to reproduce this locally is:
export MACOSX_DEPLOYMENT_TARGET=14.0
That showed a bunch of spurious warnings though:
/Users/sunrise/workspaces/qemu/include/qemu/cutils.h:144:12: warning:
'strchrnul' is only available on macOS 15.4 or newer
[-Wunguarded-availability-new]
144 | return strchrnul(s, c);
| ^~~~~~~~~
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/_string.h:198:9:
note: 'strchrnul' has been marked as being introduced in macOS 15.4 here, but
the deployment target is macOS 14.0.0
198 | strchrnul(const char *__s, int __c);
| ^
/Users/sunrise/workspaces/qemu/include/qemu/cutils.h:144:12: note: enclose
'strchrnul' in a __builtin_available check to silence this warning
144 | return strchrnul(s, c);
Sent over a new rev with guarding squashed in as needed (for the vGIC code,
availability skipped because it’s… whether the GIC is available or not is
checked in target/arm/hvf/hvf.c, and for target/arm/hvf/hvf.c, checking across
the board except for EL2/vGIC register availability which are handled via a
separate mechanism)
Sorry for this :/ should have anticipated it better
