Subject: [PATCH 1/2] x86/boot: Use '-std=gnu11' to fix build with GCC 15
|
||
MIME-Version: 1.0
|
||
Content-Type: text/plain; charset=UTF-8
|
||
Content-Transfer-Encoding: 8bit
|
||
|
||
GCC 15 changed the default C standard version to C23, which should not
|
||
have impacted the kernel because it requests the gnu11 standard via
|
||
'-std=' in the main Makefile. However, the x86 compressed boot Makefile
|
||
uses its own set of KBUILD_CFLAGS without a '-std=' value (i.e., using
|
||
the default), resulting in errors from the kernel's definitions of bool,
|
||
true, and false in stddef.h, which are reserved keywords under C23.
|
||
|
||
./include/linux/stddef.h:11:9: error: expected identifier before ‘false’
|
||
11 | false = 0,
|
||
./include/linux/types.h:35:33: error: two or more data types in declaration specifiers
|
||
35 | typedef _Bool bool;
|
||
|
||
Set '-std=gnu11' in the x86 compressed boot Makefile to resolve the
|
||
error and consistently use the same C standard version for the entire
|
||
kernel.
