=== 7 Kbuild syntax for exported headers
--- 7.1 header-y
- --- 7.2 objhdr-y
+ --- 7.2 genhdr-y
--- 7.3 destination-y
--- 7.4 generic-y
Subdirectories are visited before their parent directories.
- --- 7.2 objhdr-y
+ --- 7.2 genhdr-y
- objhdr-y specifies generated files to be exported.
+ genhdr-y specifies generated files to be exported.
Generated files are special as they need to be looked
up in another directory when doing 'make O=...' builds.
Example:
#include/linux/Kbuild
- objhdr-y += version.h
+ genhdr-y += version.h
--- 7.3 destination-y
#
# header-y - list files to be installed. They are preprocessed
# to remove __KERNEL__ section of the file
-# objhdr-y - Same as header-y but for generated files
-# genhdr-y - Same as objhdr-y but in a generated/ directory
+# genhdr-y - Same as header-y but in a generated/ directory
#
# ==========================================================================
# all headers files for this dir
