This ensures that ./configure will work fine if xen development packages are not around, rather than fail. When passing ./configure --with-xen, the lack of xen development packages become fatal. --- configure.in | 60 ++++++++++++++++++++++++++++++++------------------------- 1 files changed, 34 insertions(+), 26 deletions(-) diff --git a/configure.in b/configure.in index 447d57e..8cbbfe5 100644 --- a/configure.in +++ b/configure.in @@ -205,7 +205,7 @@ fi dnl Allow to build without Xen, QEMU/KVM, test or remote driver AC_ARG_WITH([xen], - AC_HELP_STRING([--with-xen], [add XEN support @<:@default=yes@:>@]),[],[with_xen=yes]) + AC_HELP_STRING([--with-xen], [add XEN support @<:@default=check@:>@]),[],[with_xen=check]) AC_ARG_WITH([xen-inotify], AC_HELP_STRING([--with-xen-inotify], [add XEN inotify support @<:@default=check@:>@]),[],[with_xen_inotify=check]) AC_ARG_WITH([qemu], @@ -334,6 +334,8 @@ if test "$with_libvirtd" = "yes" ; then fi AM_CONDITIONAL([WITH_LIBVIRTD], [test "$with_libvirtd" = "yes"]) +old_LIBS="$LIBS" +old_CFLAGS="$CFLAGS" XEN_LIBS="" XEN_CFLAGS="" dnl search for the Xen store library @@ -343,52 +345,58 @@ if test "$with_xen" != "no" ; then XEN_LIBS="-L$with_xen/lib64 -L$with_xen/lib" fi fail=0 - old_LIBS="$LIBS" - old_CFLAGS="$CFLAGS" CFLAGS="$CFLAGS $XEN_CFLAGS" LIBS="$LIBS $XEN_LIBS" AC_CHECK_LIB([xenstore], [xs_read], [ with_xen=yes XEN_LIBS="$XEN_LIBS -lxenstore" ],[ - if test "$with_xen" = "check" ; then - with_xen=no - else - with_xen=no + if test "$with_xen" = "yes"; then fail=1 fi + with_xen=no ]) +fi - test $fail = 1 && - AC_MSG_ERROR([You must install the Xen development package to compile Xen driver with -lxenstore]) - +if test "$with_xen" != "no" ; then AC_CHECK_HEADERS([xen/xen.h xen/version.h xen/dom0_ops.h],,[ - AC_MSG_ERROR([Cannot find standard Xen headers.

Always use AC_HELP_STRING for the help text for options at ./configure, so that the output is properly aligned. Use proper quadrigraphs for outputting the brackets. Always use autoconf-style [default=$foo] output to state the default, both where it was stated before and where it wasn't. This time, include Matthias Bolte notes regarding defaults, and removing PFX specification from phyp. --- configure.in | 100 +++++++++++++++++++++++++++++----------------------------- 1 files changed, 50 insertions(+), 50 deletions(-) diff --git a/configure.in b/configure.in index 012a96f..447d57e 100644 --- a/configure.in +++ b/configure.in @@ -205,33 +205,33 @@ fi dnl Allow to build without Xen, QEMU/KVM, test or remote driver AC_ARG_WITH([xen], -[ --with-xen add XEN support (on)],[],[with_xen=yes]) + AC_HELP_STRING([--with-xen], [add XEN support @<:@default=yes@:>@]),[],[with_xen=yes]) AC_ARG_WITH([xen-inotify], -[ --with-xen-inotify add XEN inotify support (on)],[],[with_xen_inotify=check]) + AC_HELP_STRING([--with-xen-inotify], [add XEN inotify support @<:@default=check@:>@]),[],[with_xen_inotify=check]) AC_ARG_WITH([qemu], -[ --with-qemu add QEMU/KVM support (on)],[],[with_qemu=yes]) + AC_HELP_STRING([--with-qemu], [add QEMU/KVM support @<:@default=yes@:>@]),[],[with_qemu=yes]) AC_ARG_WITH([uml], -[ --with-uml add UML support (on)],[],[with_uml=check]) + AC_HELP_STRING([--with-uml], [add UML support @<:@default=check@:>@]),[],[with_uml=check]) AC_ARG_WITH([openvz], -[ --with-openvz add OpenVZ support (on)],[],[with_openvz=yes]) + AC_HELP_STRING([--with-openvz], [add OpenVZ support @<:@default=yes@:>@]),[],[with_openvz=yes]) AC_ARG_WITH([libssh2], -[ --with-libssh2=[PFX] libssh2 location],[],[with_libssh2=yes]) + AC_HELP_STRING([--with-libssh2=@<:@PFX@:>@], [libssh2 location @<:@default=/usr/local/lib@:>@]),[],[with_libssh2=yes]) AC_ARG_WITH([phyp], -[ --with-phyp=[PFX] add PHYP support (on)],[],[with_phyp=check]) + AC_HELP_STRING([--with-phyp], [add PHYP support @<:@default=check@:>@]),[],[with_phyp=check]) AC_ARG_WITH([vbox], -[ --with-vbox add VirtualBox support (on)],[],[with_vbox=yes]) + AC_HELP_STRING([--with-vbox], [add VirtualBox support @<:@default=yes@:>@]),[],[with_vbox=yes]) AC_ARG_WITH([lxc], -[ --with-lxc add Linux Container support (on)],[],[with_lxc=check]) + AC_HELP_STRING([--with-lxc], [add Linux Container support @<:@default=check@:>@]),[],[with_lxc=check]) AC_ARG_WITH([one], -[ --with-one add ONE support (on)],[],[with_one=check]) + AC_HELP_STRING([--with-one], [add ONE support @<:@default=check@:>@]),[],[with_one=check]) AC_ARG_WITH([esx], -[ --with-esx add ESX support (on)],[],[with_esx=check]) + AC_HELP_STRING([--with-esx], [add ESX support @<:@default=check@:>@]),[],[with_esx=check]) AC_ARG_WITH([test], -[ --with-test add test driver support (on)],[],[with_test=yes]) + AC_HELP_STRING([--with-test], [add test driver support @<:@default=yes@:>@]),[],[with_test=yes]) AC_ARG_WITH([remote], -[ --with-remote add remote driver support (on)],[],[with_remote=yes]) + AC_HELP_STRING([--with-remote], [add remote driver support @<:@default=yes@:>@]),[],[with_remote=yes]) AC_ARG_WITH([libvirtd], -[ --with-libvirtd add libvirtd support (on)],[],[with_libvirtd=yes]) + AC_HELP_STRING([--with-libvirtd], [add libvirtd support @<:@default=yes@:>@]),[],[with_libvirtd=yes]) dnl dnl specific tests to setup DV devel environments with debug etc ... @@ -245,8 +245,8 @@ AC_SUBST([STATIC_BINARIES]) dnl --enable-debug=(yes|no) AC_ARG_ENABLE([debug], - [AC_HELP_STRING([--enable-debug=no/yes], - [enable debugging output])],[],[enable_debug=yes]) + [AC_HELP_STRING([--enable-debug=@<:@no|yes@:>@], + [enable debugging output @<:@default=yes@:>@])],[],[enable_debug=yes]) AM_CONDITIONAL([ENABLE_DEBUG], test x"$enable_debug" = x"yes") if test x"$enable_debug" = x"yes";
