tools/nolibc: add byteorder conversions

2026-04-07T07:27:25Z

Add some standard functions to convert between different byte orders. Conveniently the UAPI headers provide all the necessary functionality. Signed-off-by: Thomas Weißschuh Acked-by: Willy Tarreau Link: https://patch.msgid.link/20260405-nolibc-bswap-v1-1-f7699ca9cee0@weissschuh.net

tools/nolibc: explicitly list architecture headers

2026-04-02T15:11:53Z

Relying on $(wildcard) is brittle and non-deterministic. similar to all the other headers. Switch the list of architecture headers to an explicit list, Link: https://patch.msgid.link/20260401-nolibc-cleanup-v1-4-bcf4c9f5c1be@weissschuh.net Signed-off-by: Thomas Weißschuh

tools/nolibc: drop superfluous definition of Q

2026-04-02T15:11:48Z

Q is already defined by tools/scripts/Makefile.include which is included at the top of tools/include/nolibc/Makefile. Signed-off-by: Thomas Weißschuh Link: https://patch.msgid.link/20260401-nolibc-cleanup-v1-3-bcf4c9f5c1be@weissschuh.net

tools/nolibc: drop superfluous invocation of mkdir

2026-04-02T15:11:42Z

The call to 'mkdir -p $(OUTPUT)sysroot/include' will also create the sysroot directory. Drop the unnecessary explicit invocation of mkdir. Signed-off-by: Thomas Weißschuh Link: https://patch.msgid.link/20260401-nolibc-cleanup-v1-2-bcf4c9f5c1be@weissschuh.net

tools/nolibc: drop superfluous invocation of 'make headers'

2026-04-02T15:11:37Z

The headers_install target of the toplevel Makefile will already make sure that the headers are up-to-date. Drop the superfluous explicit invocation. Signed-off-by: Thomas Weißschuh Link: https://patch.msgid.link/20260401-nolibc-cleanup-v1-1-bcf4c9f5c1be@weissschuh.net

tools/nolibc: add err.h

2026-03-22T09:40:37Z

Add a few convenient helpers to print error and warning messages. Signed-off-by: Thomas Weißschuh Acked-by: Willy Tarreau Link: https://patch.msgid.link/20260318-nolibc-err-h-v4-2-08247a694bd9@weissschuh.net

tools/nolibc: always use 64-bit mode for s390 header checks

2026-01-04T09:28:56Z

32-bit s390 support was recently removed from nolibc. If the compiler defaults to 32-bit during the header checks, they fail. Make sure to always use 64-bit mode for s390 heafer checks. Fixes: 169ebcbb9082 ("tools: Remove s390 compat support") Acked-by: Willy Tarreau Acked-by: Heiko Carstens Link: https://patch.msgid.link/20251203-nolibc-headers-check-s390-v1-1-5d35e52a83ba@weissschuh.net Signed-off-by: Thomas Weißschuh

tools/nolibc: add ptrace support

2026-01-04T09:28:44Z

Add ptrace support, as it will be useful in UML. Signed-off-by: Benjamin Berg [Thomas: drop va_args usage and linux/uio.h inclusion] Signed-off-by: Thomas Weißschuh

tools/nolibc: make the "headers" target install all supported archs

2025-11-02T14:38:13Z

The efforts we go through by installing a single arch are counter productive when the base directory already supports them all, and the arch-specific files are really small. Let's make the "headers" target simply install headers for all supported archs and stop trying to build a hybrid "arch.h" file on the fly, to instead keep the generic one. Now the same nolibc headers installation will be usable with any arch-specific uapi installation. Signed-off-by: Willy Tarreau Signed-off-by: Thomas Weißschuh

tools/nolibc: add the more portable inttypes.h

2025-11-02T13:28:20Z

It's often recommended to only use inttypes.h instead of stdint.h for portability reasons since the former is always present when the latter is present, but not conversely, and the former includes the latter. Due to this some simple programs fail to build when including inttypes.h. Let's add one that simply includes nolibc.h to better support these programs.
