# Automake snippet for embedding Whippet in an autotools project.
|
||||
#
|
||||
# The including Makefile.am needs to do this, assuming Whippet is in the
|
||||
# whippet/ subdirectory:
|
||||
#
|
||||
# noinst_LTLIBRARIES =
|
||||
# WHIPPET_EMBEDDER_CPPFLAGS = -include src/my-embedder.h
|
||||
# include whippet/embed.am
|
||||
#
|
||||
# my-embedder.h should provide the various hooks that Whippet needs to
|
||||
# specialize itself to the embedder's object representation.
|
||||
#
|
||||
# The result is a libwhippet.la. To compile and link against it:
|
||||
#
|
||||
# AM_CFLAGS = $(WHIPPET_CPPFLAGS) $(WHIPPET_CFLAGS) $(WHIPPET_TO_EMBEDDER_CPPFLAGS)
|
||||
# LDADD = libwhippet.la
|
||||
# AM_LDFLAGS = $(WHIPPET_TO_EMBEDDER_LDFLAGS)
|
||||
#
|
||||
# The assumption is that the embedder will build a single copy of
|
||||
# Whippet, specialized against a single collector, a single set of
|
||||
# embedder hooks, and a single target platform. The collector and
|
||||
# platform should be chosen at configure-time. Because Automake really
|
||||
# wants the set of source files to be visible to it at automake-time, we
|
||||
# need to implement these conditions via AM_CONDITIONAL in a
|
||||
# configure.ac. For example for a parallel-mmc configuration on
|
||||
# gnu-linux, we would need:
|
||||
#
|
||||
# AM_SUBST(WHIPPET_COLLECTOR, parallel-mmc)
|
||||
# AM_CONDITIONAL(WHIPPET_COLLECTOR_SEMI, 0)
|
||||
# AM_CONDITIONAL(WHIPPET_COLLECTOR_PCC, 0)
|
||||
# AM_CONDITIONAL(WHIPPET_COLLECTOR_BDW, 0)
|
||||
# AM_CONDITIONAL(WHIPPET_COLLECTOR_MMC, 1)
|
||||
# AM_CONDITIONAL(WHIPPET_PLATFORM_GNU_LINUX, 1)
|
||||
#
|
||||
# Then there are other conditionals for compilation options:
|
||||
#
|
||||
# AM_CONDITIONAL(WHIPPET_ENABLE_DEBUG, 0)
|
||||
# AM_CONDITIONAL(WHIPPET_USE_LTTNG, 1)
|
||||
#
|
||||
# Finally, LTO should be enabled, for best performance. This should be
|
||||
# added to CFLAGS at configure-time.
|
||||
#
|
||||
# Getting all of this in there is gnarly. See the example configure.ac
|
||||
# for one take on the topic.
