Bug Description

The nih-dbus-tool executable is compiled for host architecture when cross-compiling, thus cannot be run when required during the later compilation stages, causing the upstart build to fail.

No idea how to fix this with Automake.

summary: - nih-dbus-tool is compiled for host and can't be run when cross-compiling

You should add to the configure script something like

if test "x$cross_compiling" = xyes; then

change invocations to use $(NIH_DBUS_TOOL) and make sure you have the tool preinstalled on your build machine

I've gone with a variant of what Paolo suggested. If you're cross-compiling, it'll look for nih-dbus-tool in the $PATH. In any case, overriding is permitted by setting NIH_DBUS_TOOL as you would CC, etc.

If it's not in the PATH, and you've not set it, you get something like:

configure: WARNING: nih-dbus-tool not found, but you are cross-compiling. Using built copy, which is probably not what you want. Set NIH_DBUS_TOOL maybe?

This bug was fixed in the package upstart - 0.6.3-8

upstart (0.6.3-8) karmic; urgency=low

  * Rather than calling "telinit u" after upgrade, which will lose state,
    have the umountroot initscript take care of it for us by setting a
    flag. LP: #441796.
  * Don't lose the original default runlevel if /etc/inittab exists without
    an initdefault line. LP: #405847.
  * Fix "unhandled error" in shutdown when unable to change runlevel,
    e.g. due to previous Ubiquity bug. LP: #426332.
  * Merge change from trunk that makes it possible to build Upstart using
    a previously built copy of nih-dbus-tool, especially useful when
    cross-compiling. LP: #426740.
  * Merge change from libnih to store our assertion messages in the
    glibc __abort_msg symbol so apport can pick them up. LP: #429411.
  * Merge change from libnih to fix compilation issue with eglibc due
    to changed alphasort() prototype.

Fixed in libnih 1.0.0, note that this fix will still need to be merged into software using libnih or the software updated to dynamically link to libnih instead.

Trunk uses the external libnih, and can use the installed nih-dbus-tool

milestone: 0.7.0 → 0.6.5

0.6.5 2010-02-04 "Our last, best hope for victory"

 * Since libnih has been separated out into its own project, Upstart
   no longer includes its source and now uses the installed version by

 * The external nih-dbus-tool means that cross-compilation is trivial,
   the path to it may be overriden with NIH_DBUS_TOOL=... as an
   argument to configure. (Bug: #426740)

 * Developers may still build against a local libnih source tree by
   passing --with-local-libnih=/path/to/libnih to configure.

 * There is a new initctl "reload" command, with matching
   /sbin/reload symlink. This sends the SIGHUP signal to the running
   main process of the named job instance.

 * Event operator matches in jobs now support "!=" in addition to the
   usual "=", e.g.:

  start on net-device-added INTERFACE!=eth*

   (Bug: #513035)

 * Moved D-Bus system bus reconnection trigger from SIGHUP to SIGUSR1,
   since SIGHUP is already used for a forced configuration reload and
   causes Upstart to "forget" state.

 * Fixed bug where the default runlevel would be lost when an
   /etc/inittab file exists without an initdefault line. (Bug: #405847)

 * Fixed "Unhandled error" message from shutdown. (Bug: #426332)

 * Fixed "Unhandled error" assertion crash from Upstart child
   processes when failing to spawn a job. (Bug: #451917)

 * No longer holds /dev/console open, so the SAK SysRq key will not
   kill Upstart. (Bug: #486005)

 * Restored sync() call before reboot().

 * Added missing OPTIONS section to init(8) manpage. (Bug: #449883)
