[libvirt] [PATCH] Fix --with-init-script configure option
by Matthew Booth 27 Oct '09

27 Oct '09

This was a systematic typo based on mixed use of init-script and init-scripts. --- configure.in | 14 +++++++------- daemon/Makefile.am | 4 ++-- 2 files changed, 9 insertions(+), 9 deletions(-) diff --git a/configure.in b/configure.in index 2f9db72..42ed29b 100644 --- a/configure.in +++ b/configure.in @@ -243,17 +243,17 @@ dnl init script flavor dnl AC_MSG_CHECKING([for init script flavor]) AC_ARG_WITH([init-script], - [AC_HELP_STRING([--with-init-scripts=[redhat|auto|none]], - [Style of init scripts to install (defaults to auto)])]) -if test "x$with_init_scripts" = "x" -o "x$with_init_scripts" = "xauto"; then + [AC_HELP_STRING([--with-init-script=[redhat|auto|none]], + [Style of init script to install (defaults to auto)])]) +if test "x$with_init_script" = "x" -o "x$with_init_script" = "xauto"; then if test -f /etc/redhat-release ; then - with_init_scripts=redhat + with_init_script=redhat else - with_init_scripts=none + with_init_script=none fi fi -AM_CONDITIONAL([LIBVIRT_INIT_SCRIPTS_RED_HAT], test x$with_init_scripts = xredhat) -AC_MSG_RESULT($with_init_scripts) +AM_CONDITIONAL([LIBVIRT_INIT_SCRIPT_RED_HAT], test x$with_init_script = xredhat) +AC_MSG_RESULT($with_init_script) dnl RHEL-5 has a peculiar version of Xen, which requires some special casing AC_ARG_WITH([rhel5-api], diff --git a/daemon/Makefile.am b/daemon/Makefile.am index 84aab04..ab3f238 100644 --- a/daemon/Makefile.am +++ b/daemon/Makefile.am @@ -188,7 +188,7 @@ install-logrotate: libvirtd.logrotate mkdir -p $(DESTDIR)$(sysconfdir)/logrotate.d/ $(INSTALL_DATA) $< $(DESTDIR)$(sysconfdir)/logrotate.d/libvirtd -if LIBVIRT_INIT_SCRIPTS_RED_HAT +if LIBVIRT_INIT_SCRIPT_RED_HAT install-init: libvirtd.init mkdir -p $(DESTDIR)$(sysconfdir)/rc.d/init.d $(INSTALL_SCRIPT) libvirtd.init \ @@ -222,7 +222,7 @@ install-init: uninstall-init: libvirtd.init: -endif # DBUS_INIT_SCRIPTS_RED_HAT +endif # LIBVIRT_INIT_SCRIPT_RED_HAT # This must be added last, since functions it provides/replaces # are used by nearly every other library. -- 1.6.2.5
