Here's a revised version: $(XEN_ROOT) absolutification fixes for ioemu-remote (incl stubdom) * Move code for generating an absolute version of XEN_ROOT into a common make variable set in Config.mk * Use this common code when invoking make -C ioemu-dir clean from tools/, which avoids a problem where `make clean' fails because qemu's (ioemu-remote's) build system wants to run `make clean' in `tests' but XEN_ROOT is a confection involving ../'s. * Use this common code in stubdom/Makefile, instead of $(abspath...) as the latter is a relatively new feature in GNU make and is not available in all the places that we want to be able to build (cf c/s 17997:3f23e01d31985899dbd1660b166f229f1ee74292) Signed-off-by: Ian Jackson <ian.jackson@xxxxxxxxxxxxx> diff -r 31e06b3ccf53 Config.mk --- a/Config.mk Fri Sep 12 10:41:51 2008 +0100 +++ b/Config.mk Fri Sep 12 12:18:55 2008 +0100 @@ -54,6 +54,22 @@ define cc-ver-check-closure endif endef +define absolutify_xen_root + case "$(XEN_ROOT)" in \ + /*) XEN_ROOT=$(XEN_ROOT) ;; \ + *) xen_root_lhs=`pwd`; \ + xen_root_rhs=$(XEN_ROOT)/; \ + while [ "x$${xen_root_rhs#../}" != "x$$xen_root_rhs" ]; do \ + xen_root_rhs="$${xen_root_rhs#../}"; \ + xen_root_rhs="$${xen_root_rhs#/}"; \ + xen_root_rhs="$${xen_root_rhs#/}"; \ + xen_root_lhs="$${xen_root_lhs%/*}"; \ + done; \ + XEN_ROOT="$$xen_root_lhs/$$xen_root_rhs" ;; \ + esac; \ + export XEN_ROOT +endef + ifeq ($(debug),y) CFLAGS += -g endif diff -r 31e06b3ccf53 stubdom/Makefile --- a/stubdom/Makefile Fri Sep 12 10:41:51 2008 +0100 +++ b/stubdom/Makefile Fri Sep 12 12:21:40 2008 +0100 @@ -232,8 +232,9 @@ ifeq ($(CONFIG_QEMU),ioemu) CPPFLAGS="$(TARGET_CPPFLAGS)" $(MAKE) -C ioemu LWIPDIR=$(CURDIR)/lwip-$(XEN_TARGET_ARCH) TOOLS= else [ -f ioemu/config-host.mak ] || \ - ( cd ioemu ; \ - CONFIG_STUBDOM=yes XEN_ROOT=$(abspath $(XEN_ROOT)) XEN_TARGET_ARCH=$(XEN_TARGET_ARCH) CFLAGS="$(TARGET_CFLAGS)" sh ./xen-setup --cc=$(CC) --disable-gcc-check $(IOEMU_OPTIONS)) + ( $(absolutify_xen_root); \ + cd ioemu ; \ + CONFIG_STUBDOM=yes XEN_TARGET_ARCH=$(XEN_TARGET_ARCH) CFLAGS="$(TARGET_CFLAGS)" sh ./xen-setup --cc=$(CC) --disable-gcc-check $(IOEMU_OPTIONS)) CPPFLAGS= TARGET_CPPFLAGS="$(TARGET_CPPFLAGS)" $(MAKE) -C ioemu LWIPDIR=$(CURDIR)/lwip-$(XEN_TARGET_ARCH) TOOLS= CONFIG_STUBDOM=yes endif diff -r 31e06b3ccf53 tools/Makefile --- a/tools/Makefile Fri Sep 12 10:41:51 2008 +0100 +++ b/tools/Makefile Fri Sep 12 10:53:27 2008 +0100 @@ -93,17 +93,14 @@ ioemu-dir-find: ln -sf ioemu-remote ioemu-dir; \ fi set -e; \ - case "$(XEN_ROOT)" in \ - /*) XEN_ROOT=$(XEN_ROOT) ;; \ - *) XEN_ROOT=`pwd`/$(XEN_ROOT) ;; \ - esac; \ - export XEN_ROOT; \ + $(absolutify_xen_root); \ cd ioemu-dir; \ ./xen-setup $(IOEMU_CONFIGURE_CROSS) subdir-all-ioemu-dir subdir-install-ioemu-dir: ioemu-dir-find subdir-clean-ioemu-dir: - if test -d ioemu-dir/.; then \ + set -e; if test -d ioemu-dir/.; then \ + $(absolutify_xen_root); \ $(MAKE) -C ioemu-dir clean; \ fi _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
