# Makefile for SQLITE
#
# This makefile is intended to be configured automatically using the
# configure script.
#
# The docs for many of its variables are in the primary static
# makefile, main.mk (which this one includes at runtime).

# Known TODOs/FIXMEs/TOIMPROVEs for the autosetup port, in no
# particular order...
#
# - TEA pieces.
#
# - Replace the autotools-specific distribution deliverable(s).
#
# - Confirm whether cross-compilation works and patch it
# appropriately.
#
# Maintenance reminders:
#
# - This makefile should remain as POSIX-make-compatible as possible:
#   https://pubs.opengroup.org/onlinepubs/9799919799/utilities/make.html
#
# - The naming convention of some vars, using periods instead of
#   underscores, though unconventional, was selected for a couple of
#   reasons: 1) Personal taste (for which there is no accounting).  2)
#   It is thought to help defend against inadvertent injection of
#   those vars via environment variables (because X.Y is not a legal
#   environment variable name).  "Feature or bug?" is debatable and
#   this naming convention may be reverted if it causes any grief.
#

# The top-most directory of the source tree.  This is the directory
# that contains this "Makefile.in" and the "configure" script.

# Just testing some default dir expansions...
# srcdir = @srcdir@

#
# Autotools-conventional vars which are used by package installation
# rules in main.mk.
#
# Autosetup allows the various XYZdir vars to be overridden at
# configure-time with, e.g. --libdir=X and --mandir=Y. However,
# defining them at configure-time, instead of at make-time, leads to
# later awkwardness:
#
# $ ./configure --prefix=/usr
# $ make prefix=/bar
#
# In that invocation, libdir will be /usr/foo, not /bar/foo as it
# normally should, unless the user _also_ passes libdir=... to make.
#
# In 99%+ of use cases, setting prefix=X has the desired effect of
# calculating conventional defaults for various other dirs, like
# $prefix/lib, $prefix/include, etc. If, however, we export those at
# configure-time, the passing prefix=... to make will update only
# $prefix and none of its derived dirs.
#
# Because it is more important (for our use cases) that these vars be
# overridable via a make invocation than a configure invocation, and
# they conventionally derive from $(prefix) in all but the most exotic
# of use cases, we do not export the configure-defined overrides of
# those vars to this makefile.  Instead, we export only $prefix and
# its derived vars are set to their conventional default values in
# main.mk, which users can then override at make-time as needed.
# Overriding $prefix via make will also calculate any derived vars, as
# one would expect, unless each is specifically overridden.
#
# For completeness's sake, the aforementioned conventional vars which
# are relevant to our installation rules are:
#
# datadir     = $(prefix)/share
# mandir      = $(datadir)/man
# includedir  = $(prefix)/include
# exec_prefix = $(prefix)
# bindir      = $(exec_prefix)/bin
# libdir      = $(exec_prefix)/lib
#
# Our builds do not require any of their relatives:
#
# sbindir        = $(exec_prefix)/sbin
# sysconfdir     = /etc
# sharedstatedir = $(prefix)/com
# localstatedir  = /var
# runstatedir    = /run
# infodir        = $(datadir)/info
# libexecdir     = $(exec_prefix)/libexec

# $(CFLAGS) is problematic because it is frequently overridden when

# it directly and instead add a level of indirection.  We combine
# $(CFLAGS) and $(CPPFLAGS) here because that's the way the legacy
# build did it and many builds rely on that. See main.mk for more
# details.
#
# Historical note: the pre-3.48 build only honored CPPFLAGS at
# configure-time, and expanded them into the generated Makefile. There
# are, in that build, no uses of CPPFLAGS in the configure-expanded
# Makefile. Ergo: if a client configures with CPPFLAGS=... and then
# explicitly passes CFLAGS=... to make, the CPPFLAGS will be
# lost. That behavior is retained in 3.48+ because also honoring
# CPPFLAGS at make-time may have undesired side effects on any number
# of builds.
