Subject: ACPICA compilation error on x86_64_defconfig (W=1 build)
Date: Mon, 7 Apr 2025 21:47:47 +0300 [thread overview]
Message-ID: <Z_Qd0x6bLSQjJ7Rw@smile.fi.intel.com> (raw)
v6.15-rc1 (but seems older should also be problematic) fails to compile by
Clang 19 with `make W=1`.
CC drivers/acpi/acpica/nsaccess.o
drivers/acpi/acpica/nsaccess.c:295:6: error: variable 'num_carats' set but not used [-Werror,-Wunused-but-set-variable]
295 | u32 num_carats;
| ^
1 error generated.
I looked briefly in the code and I have no idea how to fix this, as probably
__maybe_unused not an option for ACPICA. Hence this report.
Note, the in-tree defconfig is in use:
git checkout v6.15-rc1
make x86_64_defconfig
make W=1
should trigger it.
