Bare metal compilers (arm-none-eabi-) don't define __linux__. This is because the header is now in the include path for : CC arch/arm/kernel/irq.o CC kernel/sysctl.o CC crypto/api.o In file included from ../include/acpi/acpi.h:22, from ../include/linux/fw_table.h:29, from ../include/linux/acpi.h:18, from ../include/linux/irqchip.h:14, from ../arch/arm/kernel/irq.c:25: ../include/acpi/platform/acenv.h:218:2: error: #error Unknown target environment 218 | #error Unknown target environment | ^~~~~ One solution to make compilation with a bare metal compiler work again is to say the file is used with Linux from within the kernel if __KERNEL__ is defined so I did that.
