Add missing header stdbool.h to avoid errors like this one, which can happen if the including file doesn't include stdbool.h: include/linux/err.h:33:15: error: type defaults to ‘int’ in declaration of ‘bool’ [-Werror=implicit-int] 33 | static inline bool __must_check IS_ERR(__force const void *ptr) | ^~~~ include/linux/err.h:33:15: error: variable ‘bool’ declared ‘inline’ [-Werror] include/linux/err.h:33:1: error: ‘warn_unused_result’ attribute only applies to function types [-Werror=attributes] 33 | static inline bool __must_check IS_ERR(__force const void *ptr) | ^~~~~~ include/linux/err.h:33:33: error: expected ‘,’ or ‘;’ before ‘IS_ERR’ 33 | static inline bool __must_check IS_ERR(__force const void *ptr) | ^~~~~~ include/linux/err.h:38:15: error: type defaults to ‘int’ in declaration of ‘bool’ [-Werror=implicit-int] 38 | static inline bool __must_check IS_ERR_OR_NULL(__force const void *ptr) | ^~~~ include/linux/err.h:38:15: error: variable ‘bool’ declared ‘inline’ [-Werror] include/linux/err.h:38:1: error: ‘warn_unused_result’ attribute only applies to function types [-Werror=attributes] 38 | static inline bool __must_check IS_ERR_OR_NULL(__force const void *ptr) | ^~~~~~ include/linux/err.h:38:15: error: redundant redeclaration of ‘bool’ [-Werror=redundant-decls] 38 | static inline bool __must_check IS_ERR_OR_NULL(__force const void *ptr) | ^~~~ include/linux/err.h:33:15: note: previous declaration of ‘bool’ was here 33 | static inline bool __must_check IS_ERR(__force const void *ptr) | ^~~~ include/linux/err.h:38:33: error: expected ‘,’ or ‘;’ before ‘IS_ERR_OR_NULL’ 38 | static inline bool __must_check IS_ERR_OR_NULL(__force const void *ptr) | ^~~~~~~~~~~~~~ include/linux/err.h: In function ‘PTR_ERR_OR_ZERO’: include/linux/err.h:58:6: error: implicit declaration of function ‘IS_ERR’ [-Werror=implicit-function-declaration] 58 | if (IS_ERR(ptr)) | ^~~~~~ include/linux/err.h:58:6: error: nested extern declaration of ‘IS_ERR’ [-Werror=nested-externs] Signed-off-by: Alexandru Elisei <alexandru.elisei@xxxxxxx> --- include/linux/err.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/include/linux/err.h b/include/linux/err.h index a729120644d5..1256c7abfefa 100644 --- a/include/linux/err.h +++ b/include/linux/err.h @@ -1,6 +1,8 @@ #ifndef _LINUX_ERR_H #define _LINUX_ERR_H +#include <stdbool.h> + #include <linux/compiler.h> #include <linux/types.h> -- 2.31.1 _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
