tools/nolibc: always use 64-bit mode for s390 header checks32-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.netSigned-off-by: Thomas Weißschuh List of files: /linux/tools/include/nolibc/Makefile

1868c027b6527abfa9ab8172a905acc5809849ee - tools/nolibc: make the "headers" target install all supported archs

Sun, 02 Nov 2025 15:10:45 +0100

tools/nolibc: make the "headers" target install all supported archsThe efforts we go through by installing a single arch are counterproductive when the base directory already supports them all, andthe arch-specific files are really small. Let's make the "headers"target simply install headers for all supported archs and stoptrying to build a hybrid "arch.h" file on the fly, to instead keepthe generic one. Now the same nolibc headers installation will beusable with any arch-specific uapi installation.Signed-off-by: Willy Tarreau Signed-off-by: Thomas Weißschuh List of files: /linux/tools/include/nolibc/Makefile

Sun, 02 Nov 2025 14:21:28 +0100

tools/nolibc: add the more portable inttypes.hIt's often recommended to only use inttypes.h instead of stdint.h forportability reasons since the former is always present when the latteris present, but not conversely, and the former includes the latter. Dueto this some simple programs fail to build when including inttypes.h.Let's add one that simply includes nolibc.h to better support theseprograms.Signed-off-by: Willy Tarreau Signed-off-by: Thomas Weißschuh List of files: /linux/tools/include/nolibc/Makefile

Sun, 02 Nov 2025 11:46:11 +0100

tools/nolibc: provide the portable sys/select.hModern programs tend to include sys/select.h to get FD_SET() andFD_CLR() definitions as well as struct fd_set, but in our case itdidn't exist.The definitions were moved from types.h to sys/select.h, which isnow included from nolibc.h, and the sys_select() definition movedthere as well from sys.h.Signed-off-by: Willy Tarreau [Thomas: adapt to current -next branch]Signed-off-by: Thomas Weißschuh List of files: /linux/tools/include/nolibc/Makefile
