The headers.chk target in tools/Rules.mk tries to compile all headers stand alone for testing them not to include any internal header. Unfortunately the headers tested against are not complete, as any header for a Xen library is not included in the include path of the test compile run, resulting in a failure in case any of the tested headers in including an official Xen library header. Fix that by copying the official headers located in tools/libs/*/include to tools/include. In order to support libraries with header name other than xen<lib>.h or with multiple headers add a LIBHEADER make variable a lib specific Makefile can set in that case. Move the headers.chk target from Rules.mk to libs.mk as it is used for libraries in tools/libs only. Add NO_HEADERS_CHK variable to skip checking headers as this will be needed e.g. for libxenctrl.

# Compiling and linking against in tree libraries.

# In order to compile and link against an in-tree library various
|
|
# cpp/compiler/linker options are required.

|
|
# For example consider a library "libfoo" which itself uses two other
|
|
# libraries:
|
|
# libbar - whose use is entirely internal to libfoo and not exposed
|
|
# to users of libfoo at all.
|
|
# libbaz - whose use is entirely internal to libfoo but libfoo's
|
|
# public headers include one or more of libbaz's
|
|
# public headers. Users of libfoo are therefore transitively
|
|
# using libbaz's header but not linking against libbaz.
|
|
#
|
|
# SHDEPS_libfoo: Flags for linking recursive dependencies of
|
|
# libfoo. Must contain SHLIB for every library which
|
|
# libfoo links against. So must contain both
|
|
# $(SHLIB_libbar) and $(SHLIB_libbaz).
|
|
#
|
|
# SHLIB_libfoo: Flags for recursively linking against libfoo. Must
|
|
# contains SHDEPS_libfoo and:
|
|
# -Wl,-rpath-link=<directory containing libfoo.so>
|
|
#
|
|
# CFLAGS_libfoo: Flags for compiling against libfoo. Must add the
|
|
# directories containing libfoo's headers to the
|
|
# include path. Must recursively include
|
|
# $(CFLAGS_libbaz), to satisfy the transitive inclusion
|
|
# of the headers but not $(CFLAGS_libbar) since none of
|
|
# libbar's headers are required to build against
|
|
# libfoo.
|
|
#
|
|
# LDLIBS_libfoo: Flags for linking against libfoo. Must contain
|
|
# $(SHDEPS_libfoo) and the path to libfoo.so
|
|
#
|
|
# Consumers of libfoo should include $(CFLAGS_libfoo) and
|
|
# $(LDLIBS_libfoo) in their appropriate directories. They should not
|

# include any CFLAGS or LDLIBS relating to libbar or libbaz unless
