# -*- Mode: makefile -*-
#
# To use:
#
# In configure.ac:
# add -Wno-portability to AM_INIT_AUTOMAKE
# add GLIB_CONFIG([min-version[, required-modules]])
# (remove AM_PATH_GLIB_2_0 and GLIB_GSETTINGS)
#
# Add to Makefile.am where your library/program is built:
# include $(GLIB_MAKEFILE)
#
# BUILT_SOURCES = $(GLIB_GENERATED)
#
# Add *.stamp to .gitignore
#
# Add a GLIB_GENERATED variable with the files you want to generate,
# as described below. (The examples below use filenames with hyphens,
# eg foo-marshal.h, but you can omit the hyphens if that matches your
# file naming scheme better.)
#
# You do not need to modify CLEANFILES or EXTRA_DIST for any of these
# macros.
# glib-genmarshal
#
# To generate signal marshallers, add files with names ending in
# "marshal.h" and "marshal.c" to GLIB_GENERATED:
#
# GLIB_GENERATED += foo-marshal.h foo-marshal.c
# foo_marshal_sources = aaa.c bbb.c ccc.c ddd.c
#
# Makefile.glib will then generate a foo-marshal.list file containing
# all _foo_marshal_* functions referenced by $(foo_marshal_sources),
# and will rebuild foo-marshal.c/foo-marshal.h whenever the list
# changes.
#
# For your convenience, any .h files or $(GLIB_GENERATED) files in
# $(foo_marshal_sources) will be ignored. This means you can usually just
# set foo_marshal_sources to the value of your library/program's
# _SOURCES variable, even if that variable contains foo-marshal.c.
#
# You can set GLIB_GENMARSHAL_H_FLAGS and GLIB_GENMARSHAL_C_FLAGS (or
# an appropriate file-specific variable, eg
# foo_marshal_GENMARSHAL_H_FLAGS) to set/override glib-genmarshal
# options.
# glib-mkenums
#
# To generate enum type registrations, add files with names ending
# in "-enum-types.[ch]" or "enumtypes.[ch]" to GLIB_GENERATED:
#
# GLIB_GENERATED += foo-enum-types.h foo-enum-types.c
# foo_enum_types_sources = aaa.h bbb.h ccc.h ddd.h
#
# Makefile.glib will create a list all of the enum/flags types
# declared in $(foo_enum_type_sources), and will rebuild
# foo-enum-types.c/foo-enum-types.h whenever that list changes. (No
# template files are required.)
#
# For your convenience, any .c files or $(GLIB_GENERATED) files in
# $(foo_enum_types_sources) will be ignored. This means you can
# usually set foo_enum_types_sources to the value of your
# library/program's _HEADERS and/or _SOURCES variables, even if that
# contains foo-enum-types.h.
#
# You can set GLIB_MKENUMS_H_FLAGS and GLIB_MKENUMS_C_FLAGS (or an
# appropriate file-specific variable, eg
# foo_enum_types_MKENUMS_H_FLAGS) to set/override glib-mkenums
# options. In particular, you can do:
#
# GLIB_MKENUMS_C_FLAGS = --fhead "\#define FOO_I_KNOW_THIS_IS_UNSTABLE"
#
# (The backslash is necessary to keep make from thinking the "#" is
# the start of a comment.)
# glib-compile-schemas
#
# Any foo.gschemas.xml files listed in gsettingsschema_DATA will be
# validated before installation, and (if --disable-schemas-compile was
# not passed) compiled after installation.
#
# To build an enums file, add it to GLIB_GENERATED (in addition to
# gsettingsschema_DATA):
#
# GLIB_GENERATED += org.gnome.foo.enums.xml
# org_gnome_foo_enums_xml_sources = aaa.h bbb.h ccc.h ddd.h
#
# All enums files will be built before any schema files are validated.
########
# Notes on Makefile.glib hacking:
#
# - The exact rules that automake generates for a Makefile vary
# depending on what sorts of things were done in the Makefile.am,
# so we have to be careful with what rules we assume are there.
# In particular, (a) the glue to handle BUILT_SOURCES and the
# various hooks won't be output unless those things were
# referenced in the Makefile.am, and (b) a Makefile.am with
# SUBDIRS will get different rules than one without.
#
# - Build rules should always refer to their dependencies via $^,
# not by reusing a variable that is listed in the rule's
# dependencies. This is needed to make srcdir!=builddir builds
# work. You can use $(filter)/$(filter-out) if $^ has things
# you don't want in it.
#
# - When using a filename as something other than a filename,
# consider whether you need to wrap it in $(notdir) to get the
# right result when that file is being pulled out of a
# subdirectory.
#
# - All private variables should be prefixed with _glib or _GLIB
#
# - "make -qp > makefile.out" will give you a copy of the
# Makefile after all macros are expanded.
#
# The genmarshal code is commented; the mkenums and schema code is
# generally similar.
