Create a basic Makefile to build and install libxenlight Golang bindings. Also add a stub package which only opens libxl context. Include a global xenlight.Ctx variable which can be used as the default context by the entire program if desired. For now, return simple errors. Proper error handling will be added in next patch. Until we get configure support, disable it by default. It can be enabled either by adding "CONFIG_GOLANG=y" to .config, or adding it to the 'make' line.

# 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
|
|
# they use those libraries directly (not via libfoo) too.
|

#
|

# Consumers of libfoo should not directly use $(SHDEPS_libfoo) or
