* tools/build: Introduce {PREPEND,APPEND}_{LIB,INCLUDES}Roger Pau Monne2011-11-141-4/+4
| | | | | | | | | | | | | | | | | | | | | | | Create two new variables called APPEND_ and PREPEND_ to add compile flags at the beginning or at the end of the search path. Added a new semantic for user defined compile flags, here is the list of possible options: PREPEND_LIB: add libraries to the search path before xen (before xen installation folders). PREPEND_INCLUDES: add headers to the search path before xen (before xen installation folders). APPEND_LIB: add libraries to the search path at the end (after all xen installation folders have been added). APPEND_INCLUDES: add libraries to the search path at the end (after all xen installation folders have been added). EXTRA_INCLUDES and EXTRA_LIB can still be used, and they will have the same effect as PREPEND_INCLUDES and PREPEND_LIB.

* tools: remove pattern matched linking rulesIan Campbell2011-03-311-7/+11
| | | | | | | | | Most subdirs only build a single tool to start with and those which build multiple tools often have different linkage requirements.

* tools: do not link against unused libraries.Ian Campbell2011-03-171-4/+15
| | | | | | | | | | | | | | | | | A fair few things under tools link against libraries which they don't even use. Most of this appears to come from copy-and-pasting previous Makefile snippets and cargo-culting plus the tendency to define global $(LIBS) even for Makefiles which build multiple separate utilities or libraries. Identified by comparing a build with --as-needed to one without by looking at the NEEDED header of all ELF objects.

* build: Make XEN_ROOT an absolute path.Keir Fraser2011-03-171-1/+1
| | | | | | | | Otherwise make can search the path relative to certain standard paths such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in Config.mk suffers from this). Signed-off-by: Keir Fraser <keir@xen.org>
* split LDLIBS from LDFLAGS to fix link errors in recent toolchainsStefano Stabellini2010-08-111-1/+1
| | | | | | | | | | | | | | | | Linker command lines are order-sensitive. Move linker options -Lfoo -lfoo from LDFLAGS to LDLIBS and place this new variable after the objects to link. This resolves build errors in xenpagin and blktap with recent toolchains. rename SHLIB_CFLAGS to SHLIB_LDFLAGS rename LDFLAGS_* to LDLIBS_* move LDFLAGS usage after CFLAGS in CC calls remove stale comments in xenpaging Makefile Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com>
* Use -MMD -MF in tools/* rather than -Wp,-M...Keir Fraser2009-01-121-6/+2
| | | | | | | | | | | | | | | | | | | | | | If you use -MMD -MF then the correct .o filename is written to the .*.d file as the compiler driver arranges everything. This was done in 19010:275abe1c5d24 for the hypervisor. In this patch we do the same elsewhere in the xen-unstable tree, particularly tools/. Specifically: * Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS. * Remove -Wp,-MD... from every other Makefile * Remove setting of DEPS from every other Makefile * Ensure that every Makefile says -include $(DEPS) * Ensure that every Makefile's clean target removes $(DEPS) Some Makefiles were already halfway there, but often for a different variable name eg PROG_DEP. The variable name is now standardised in Rules.mk as DEPS. I have done a test build with this change, on Debian etch. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
