It works well here because all the exported headersare located in sub-directories, like <linux/*.h>, <asm/*.h>.Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> List of files: /linux-6.15/usr/include/.gitignore Sat, 24 Apr 2021 19:47:19 +0000 Masahiro Yamada <masahiroy@kernel.org> http://172.16.0.5:8080/history/linux-6.15/usr/include/.gitignore#d198b34f .gitignore: add SPDX License IdentifierAdd SPDX License Identifier to all .gitignore files.Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> List of files: /linux-6.15/usr/include/.gitignore Tue, 03 Mar 2020 13:35:59 +0000 Masahiro Yamada <masahiroy@kernel.org> http://172.16.0.5:8080/history/linux-6.15/usr/include/.gitignore#d6fc9fcb kbuild: compile-test exported headers to ensure they are self-containedMultiple people have suggested compile-testing UAPI headers to ensurethey can be really included from user-space. "make headers_check" isobviously not enough to catch bugs, and we often leak unresolvedreferences to user-space.Use the new header-test-y syntax to implement it. Please note exportedheaders are compile-tested with a completely different set of compilerflags. The header search path is set to $(objtree)/usr/include sinceexported headers should not include unexported ones.We use -std=gnu89 for the kernel space since the kernel code highlydepends on GNU extensions. On the other hand, UAPI headers should bewritten in more standardized C, so they are compiled with -std=c90.This will emit errors if C++ style comments, the keyword 'inline', etc.are used. Please use C style comments (/* ... */), '__inline__', etc.in UAPI headers.There is additional compiler requirement to enable this test becausemany of UAPI headers include <stdlib.h>, <sys/ioctl.h>, <sys/time.h>,etc. directly or indirectly. You cannot use kernel.org pre-builttoolchains [1] since they lack <stdlib.h>.I reused CONFIG_CC_CAN_LINK to check the system header availability.The intention is slightly different, but a compiler that can linkuserspace programs provide system headers.For now, a lot of headers need to be excluded because they cannotbe compiled standalone, but this is a good start point.[1] https://mirrors.edge.kernel.org/pub/tools/crosstool/index.htmlSigned-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>Reviewed-by: Sam Ravnborg <sam@ravnborg.org> List of files: /linux-6.15/usr/include/.gitignore Mon, 01 Jul 2019 00:58:40 +0000 Masahiro Yamada <yamada.masahiro@socionext.com>
