From c0412fedf85034d9e00e84e5ae5c415df1df6284 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Thu, 24 Apr 2014 17:39:12 +0200 Subject: build: Add missing function checks for optional daemon features. * config-daemon.ac: Check for lchown, posix_fallocate, vfork, sched_setaffinity, statvfs, nanosleep, and strsignal. As a side effect, this enables daemon features depending on the corresponding feature test macros. --- config-daemon.ac | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/config-daemon.ac b/config-daemon.ac index 1169bb6ef4..08a72a0c4c 100644 --- a/config-daemon.ac +++ b/config-daemon.ac @@ -67,9 +67,14 @@ if test "x$guix_build_daemon" = "xyes"; then AC_CHECK_FUNCS([chroot unshare]) AC_CHECK_HEADERS([sched.h sys/param.h sys/mount.h]) - dnl Check for lutimes, optionally used for changing the mtime of - dnl symlinks. - AC_CHECK_FUNCS([lutimes]) + dnl lutimes and lchown: used when canonicalizing store items. + dnl posix_fallocate: used when extracting archives. + dnl vfork: to speed up spawning of helper programs. + dnl sched_setaffinity: to improve RPC locality. + dnl statvfs: to detect disk-full conditions. + dnl strsignal: for error reporting. + AC_CHECK_FUNCS([lutimes lchown posix_fallocate vfork sched_setaffinity \ + statvfs nanosleep strsignal]) dnl Check whether the store optimiser can optimise symlinks.
