CONFIG_HEADERS_CHECK: Run sanity checks on uapi headers when building 'all'

General informations

The Linux kernel configuration item CONFIG_HEADERS_CHECK has multiple definitions:

Run sanity checks on uapi headers when building 'all' found in lib/Kconfig.debug

The configuration item CONFIG_HEADERS_CHECK:

• prompt: Run sanity checks on uapi headers when building 'all'
• type: bool
• depends on: CONFIG_HEADERS_INSTALL
• defined in lib/Kconfig.debug
• found in Linux kernels: 5.3–5.4

Help text

This option will run basic sanity checks on uapi headers when building the 'all' target, for example, ensure that they do not attempt to include files which were not exported, etc.

If you're making modifications to header files which are relevant for userspace, say 'Y'.

Run 'make headers_check' when building vmlinux found in lib/Kconfig.debug

The configuration item CONFIG_HEADERS_CHECK:

• prompt: Run 'make headers_check' when building vmlinux
• type: bool
• depends on: ! CONFIG_UML
• defined in lib/Kconfig.debug
• found in Linux kernels: 2.6.19–2.6.39, 3.0–3.19, 4.0–4.20, 5.0–5.2

Help text

This option will extract the user-visible kernel headers whenever building the kernel, and will run basic sanity checks on them to ensure that exported files do not attempt to include files which were not exported, etc.

If you're making modifications to header files which are relevant for userspace, say 'Y', and check the headers exported to $(INSTALL_HDR_PATH) (usually 'usr/include' in your build tree), to make sure they're suitable.
