tools: cache the configure results of eleven more autotools tools

2026-09-22T18:29:59Z

Configure stage without a cache against a warm cache: mtools 3.34 s -> 0.28 s gengetopt 4.39 s -> 2.13 s fakeroot 10.97 s -> 8.73 s xz 4.32 s -> 2.17 s libressl 3.07 s -> 1.46 s flex 12.32 s -> 10.98 s expat 2.74 s -> 1.52 s bc 1.34 s -> 0.38 s dosfstools 3.13 s -> 2.54 s libtool 2.86 s -> 2.29 s mtd-utils 4.06 s -> 3.56 s flex, fakeroot, dosfstools and mtd-utils run autoreconf in the same stage, and the cache does not reach that part. Each of the eleven configures the same way with a warm cache as it does without one: the check configures three times, without a cache, with a cold cache and with a warm cache, and every generated file of the first and the last run is identical. A static scan of each configure script found no cache check that changes CFLAGS, CPPFLAGS, LDFLAGS or LIBS without restoring it. patchelf, mklibs and automake pass the same check but gain less than half a second, so they stay out. make world after make tools/clean now takes 121 s against 177 s with cold caches.

tools/flex: respect STAGING_DIR_HOST

2024-09-24T18:48:43Z

flex currently leaks the path of m4 as found on the build host. While it is possible to override this using the M4 environment variable (which we always did for autotools based builds) when using CMake or Ninja the M4 variable is not set. One easy fix is to make flex take STAGING_DIR_HOST into account and expect m4 there if that variable is set in the environment. Signed-off-by: Daniel Golle

tools/flex: fix PKG_CPE_ID

2024-04-27T10:08:11Z

cpe:/a:westes:flex is the correct CPE ID for flex: https://nvd.nist.gov/products/cpe/search/results?keyword=cpe:2.3:a:westes:flex Fixes: c61a2395140d92cdd37d3d6ee43a765427e8e318 (add PKG_CPE_ID ids to package and tools) Signed-off-by: Fabrice Fontaine

tools/flex: override SUBDIRS variable with Makefile

2023-05-04T04:07:28Z

Instead of editing the SUBDIRS variable with a patch, it can be overriden at the end of the command line when invoking Make. Skip the build for po files as well, which is causing a conflict depending on the version of gettext detected, and macros present. Signed-off-by: Michael Pratt

tools: add Host/Uninstall where possible

2022-10-19T22:33:22Z

This cleans staging_dir when calling tool/x/clean. Signed-off-by: Rosen Penev

flex: Add a lex symlink

2018-11-25T18:23:03Z

Some packages like libpfring assume the presense of lex, which on some other systems is a symlink to flex but not all. Symlink flex to fix compilation. Arch Linux and Fedora do this as far as I know. Signed-off-by: Rosen Penev
