#!/usr/bin/make # ^^^^ help out editors which guess this file's type. # # 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). # all: ######################################################################## # # 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. # TOP = @abs_top_srcdir@ # # Autotools-conventional vars which are used by package installation # rules in main.mk. To get sane handling when a user overrides only # a subset of these, we perform some acrobatics with these vars # in the configure script: see [proj-remap-autoconf-dir-vars] for # full details. # # 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 # prefix = @prefix@ datadir = @datadir@ mandir = @mandir@ includedir = @includedir@ exec_prefix = @exec_prefix@ bindir = @bindir@ libdir = @libdir@ INSTALL = @BIN_INSTALL@ AR = @AR@ AR.flags = cr # TODO? Add a configure test to determine this? CC = @CC@ B.cc = @CC_FOR_BUILD@ @BUILD_CFLAGS@ T.cc = $(CC) # # $(CFLAGS) is problematic because it is frequently overridden when # invoking make, which loses things like -fPIC. So... we avoid using # 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+. # CFLAGS = @CFLAGS@ @CPPFLAGS@ # # $(LDFLAGS.configure) represents any LDFLAGS=... the client passes to # configure.
