Well, the parallel build doesn't work as there are not dependencies set correctly. When running 'make -j' I see this error: make[2]: Entering directory '/home/zippy/work/libvirt/libvirt.git/src' GEN util/virkeymaps.h GEN locking/lock_protocol.h make[2]: *** No rule to make target 'xenconfig/xen_xl_disk.h', needed by 'all'. Stop. make[2]: *** Waiting for unfinished jobs.... GEN lxc/lxc_controller_dispatch.h The fix is to correctly set dependencies by letting make know that .c and .h are to be generated from .l. Moreover, the section is moved closer to the other section which uses it. Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- I'm not fully satisfied with this patch yet. I mean, for some reason it creates 'src/.h' file, but hey - it makes parallel build work again. Any brighter idea appreciated. src/Makefile.am | 36 +++++++++++++++++++----------------- 1 file changed, 19 insertions(+), 17 deletions(-) diff --git a/src/Makefile.am b/src/Makefile.am index c6d736e..7619cf0 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -1000,23 +1000,6 @@ CPU_SOURCES = \ VMX_SOURCES = \ vmx/vmx.c vmx/vmx.h -AM_LFLAGS = -Pxl_disk_ --header-file=../$*.h -LEX_OUTPUT_ROOT = lex.xl_disk_ -BUILT_SOURCES += xenconfig/xen_xl_disk.c xenconfig/xen_xl_disk.h -# Generated header file is not implicitly added to dist -EXTRA_DIST += xenconfig/xen_xl_disk.h -CLEANFILES += xenconfig/xen_xl_disk.h xenconfig/xen_xl_disk.c - -XENXLDISKPARSER_SOURCES = xenconfig/xen_xl_disk.l - -XENCONFIG_SOURCES = \ - xenconfig/xenxs_private.h \ - xenconfig/xen_common.c xenconfig/xen_common.h \ - xenconfig/xen_sxpr.c xenconfig/xen_sxpr.h \ - xenconfig/xen_xm.c xenconfig/xen_xm.h \ - xenconfig/xen_xl.c xenconfig/xen_xl.h \ - xenconfig/xen_xl_disk.h - pkgdata_DATA = cpu/cpu_map.xml EXTRA_DIST += $(pkgdata_DATA) @@ -1078,6 +1061,25 @@ libvirt_xenxldiskparser_la_CFLAGS = \ libvirt_xenxldiskparser_la_SOURCES = \ $(XENXLDISKPARSER_SOURCES) +AM_LFLAGS = -Pxl_disk_ --header-file=../$*.h +XENXLDISKPARSER_GENERATED = xenconfig/xen_xl_disk.c xenconfig/xen_xl_disk.h +BUILT_SOURCES += $(XENXLDISKPARSER_GENERATED) +EXTRA_DIST += $(XENXLDISKPARSER_GENERATED) +MAINTAINERCLEANFILES += $(XENXLDISKPARSER_GENERATED) + +XENXLDISKPARSER_SOURCES = xenconfig/xen_xl_disk.l + +$(XENXLDISKPARSER_GENERATED): $(XENXLDISKPARSER_SOURCES) + $(SHELL) $(YLWRAP) $< lex.xl_disk_.c $@ -- $(LEXCOMPILE) + +XENCONFIG_SOURCES = \ + xenconfig/xenxs_private.h \ + xenconfig/xen_common.c xenconfig/xen_common.h \ + xenconfig/xen_sxpr.c xenconfig/xen_sxpr.h \ + xenconfig/xen_xm.c xenconfig/xen_xm.h \ + xenconfig/xen_xl.c xenconfig/xen_xl.h \ + xenconfig/xen_xl_disk_i.h + noinst_LTLIBRARIES += libvirt_xenconfig.la libvirt_la_BUILT_LIBADD += libvirt_xenconfig.la libvirt_xenconfig_la_CFLAGS = \ -- 2.0.5
