However, I think we should not treat it as "at least" in general, but only for the "newer" case. In other words, I think we should add BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_NEWER (and the equivalent in toolchain-external) which selects BR2_TOOLCHAIN_HEADERS_NEWER, and make the check > 5.0 (rather than == something) in that case. It's a bigger change though.

In linux-headers.mk: ifeq ($(BR2_KERNEL_HEADERS_VERSION)$(BR2_KERNEL_HEADERS_AS_KERNEL)$(BR2_KERNEL_HEADERS_CUSTOM_TARBALL)$(BR2_KERNEL_HEADERS_CUSTOM_GIT),y) define LINUX_HEADERS_CHECK_VERSION $(call check_kernel_headers_version,\ $(STAGING_DIR),\ $(call qstrip,$(BR2_TOOLCHAIN_HEADERS_AT_LEAST))) endef LINUX_HEADERS_POST_INSTALL_STAGING_HOOKS += LINUX_HEADERS_CHECK_VERSION endif If we use BR2_KERNEL_HEADERS_AS_KERNEL, I think it's no necessary to check _AT_LEAST. Because user has specified the linux version and he want the version without more checking. Best Regards Guo Ren
