Commitb9e89b340e(sudo: bump version) introduced the explicit build of mksigname and mksiglist as host tools, as they were required to run on the build machine, to generate C code then used to build the target program. This is now failing to build since the bump to sudo 1.9.15p5 in commitc87746afef(package/sudo: security bump to version 1.9.15p5) (lines manually wrapped and slightly elided for ease of reviewing): /usr/bin/cpp \ -I/home/ymorin/dev/buildroot/O/master/per-package/sudo/host/include \ -I../../include \ -I../.. \ ./sys_signame.h \ | /usr/bin/sed -e '1,/^int sudo_end_of_headers;/d' -e '/^#/d' > mksigname.h In file included from /usr/include/features.h:394, from /usr/include/sys/types.h:25, from ./sys_signame.h:4: /usr/include/features-time64.h:26:5: error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64" 26 | # error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64" | ^~~~~ /usr/bin/gcc -I../../include -I../.. -I. -I. \ -D_PATH_SUDO_CONF=\"/etc/sudo.conf\" -I/home/ymorin/dev/buildroot/O/master/per-package/sudo/host/include \ -DDEFAULT_TEXT_DOMAIN=\"sudo\" \ -O2 \ -I/home/ymorin/dev/buildroot/O/master/per-package/sudo/host/include \ ./mksigname.c -o mksigname In file included from /usr/include/features.h:394, from /usr/include/bits/libc-header-start.h:33, from /usr/include/stdlib.h:26, from ./mksigname.c:27: /usr/include/features-time64.h:26:5: error: #error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64" 26 | # error "_TIME_BITS=64 is allowed only with _FILE_OFFSET_BITS=64" | ^~~~~ make[2]: *** [Makefile:263: mksigname] Error 1 The core of the issue has not been really identified, but it turns out that neither mksiglist nor mksignames is used during the build. This has been tested with a minimal sudo with no option, and with a sudo with all options enabled (linux-pam, zlib, opensldap, and openssl), with the three types of C libraries (glibc, musl, and uClibc-ng). Digging in the sudo buildsystem did not reveal an obvious reason when those would be needed either. Drop the hook now it seems it is no longer used and is atually breaking the build. Fixes: http://autobuild.buildroot.org/results/72f/72ff18fb9b41394a29006f881ee1fbea67a66a09/ Note that there is a second issue in there: the call to the host cpp fails, but since it is on the LHS of a pipe, the error is lost, as the RHS of the pipe (the sed call) succeeds; a fix for that will be sent in a separate patch.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
