[libvirt] [PATCH] build: fix 'make -C src check' under subset builds

Another build failure detected on cygwin, where lxc is not built. The lxc_monitor_protocol.c file requires the use of $(XDR_CFLAGS), but should only be built on platforms where WITH_LXC is true; however, 'make -C src check' was unconditionally trying to build the .o file (and with the wrong CFLAGS) in order to validate the matching -structs file. Rework the checks to only test files that are built for the current configuration. * src/Makefile.am (PROTOCOL_STRUCTS): Split list by which files are currently being compiled. (EXTRA_DIST): Ensure that -structs files are shipped even when not built. (check-protocol): Declare unconditionally, now that the condition has been moved into PROTOCOL_STRUCTS. (libvirt_driver_lxc_impl_la_CFLAGS): Add $(XDR_CFLAGS). (libvirt_net_rpc_la_SOURCES): List generated files more compactly. Signed-off-by: Eric Blake <eblake(a)redhat.com&gt; --- This is a build-breaker, but I'm still in the middle of running a (lengthy) 'make distcheck' on several platforms before pushing, so a review wouldn't hurt. src/Makefile.am | 35 ++++++++++++++++++++++------------- 1 file changed, 22 insertions(+), 13 deletions(-) diff --git a/src/Makefile.am b/src/Makefile.am index 09311b7..20ba1c8 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -428,18 +428,35 @@ check-symsorting: EXTRA_DIST += check-symfile.pl check-symsorting.pl # Keep this list synced with RPC_PROBE_FILES -PROTOCOL_STRUCTS = \ +PROTOCOL_STRUCTS = +if WITH_REMOTE +PROTOCOL_STRUCTS += \ $(srcdir)/remote_protocol-structs \ $(srcdir)/lxc_protocol-structs \ $(srcdir)/qemu_protocol-structs \ + $(NULL) +endif WITH_REMOTE +PROTOCOL_STRUCTS += \ $(srcdir)/virnetprotocol-structs \ $(srcdir)/virkeepaliveprotocol-structs \ + $(NULL) +if WITH_LXC +PROTOCOL_STRUCTS += \ $(srcdir)/lxc_monitor_protocol-structs \ + $(NULL) +endif WITH_LXC +if WITH_LIBVIRTD +PROTOCOL_STRUCTS += \ $(srcdir)/lock_protocol-structs \ $(NULL) +endif WITH_LIBVIRTD + +# The various -structs files live in git, because they are only +# conditionally generated; ship one -structs file for each .x file. +EXTRA_DIST += $(notdir $(RPC_PROBE_FILES:.x=-structs))) -if WITH_REMOTE check-protocol: $(PROTOCOL_STRUCTS) $(PROTOCOL_STRUCTS:structs=struct) +.PHONY: check-protocol $(PROTOCOL_STRUCTS:structs=struct) # The .o file that pdwtags parses is created as a side effect of running # libtool; but from make's perspective we depend on the .lo file. @@ -458,13 +475,6 @@ $(srcdir)/lock_protocol-struct: \ $(srcdir)/%-struct: locking/lockd_la-%.lo $(PDWTAGS) -else !WITH_REMOTE -# The $(PROTOCOL_STRUCTS) files must live in git, because they cannot be -# re-generated when configured --without-remote. -check-protocol: -endif !WITH_REMOTE -EXTRA_DIST += $(PROTOCOL_STRUCTS) - check-drivername: $(AM_V_GEN)$(PERL) $(srcdir)/check-drivername.pl \ $(srcdir)/driver.h \ @@ -538,7 +548,6 @@ EXTRA_DIST += check-driverimpls.pl check-aclrules.pl check-aclperms.pl check-local: check-protocol check-symfile check-symsorting \ check-drivername check-driverimpls check-aclrules \ check-aclperms -.PHONY: check-protocol $(PROTOCOL_STRUCTS:structs=struct) # Mock driver, covering domains, storage, networks, etc TEST_DRIVER_SOURCES = \ @@ -1183,6 +1192,7 @@ endif !
