# Makefile for SQLITE
#
# This makefile is intended to be configured automatically using the
# configure script. Hand editing may not work as expected because
# certain blocks are added or removed depending on configure-time
# information.
#
# The docs for many of its variables are in the primary static
# makefile, main.mk (which this one includes at runtime).

#XX# Lines starting with #XX# are TODOs for the port to autosetup.
#
# Known TODOs/FIXMEs/TOIMPROVEs for the autosetup port, in no
# particular order...
#
# - libreadline detection and handling of its -I, -L, and -l flags.
# These can vary considerably across systems. e.g. some need -lncurses,
# and some don't know what an -lncurses is.
#
# - TEA pieces.
#
# - Replace the autotools-specific distribution deliverable(s).
#
# - Provide Makefile.msc, Makefile.linux-gcc, and any required similar
# makefile stubs for environments where the configure script will not
# run. The core makefile rules in main.mk "should" apply as-is for
# most platforms.  We can potentially generate those makefiles, along
# with main.mk, like we do in the Fossil project.
#
# - Confirm whether cross-compilation works and patch it
# appropriately.
#
# - There are some lingering dependencies issues which cause a
# re-configure to trigger more often than it should.  This is
# especially a problem in parallel builds, which may launch multiple
# re-configures in parallel.  GNU Make offers ways of controlling
# that, but we're limited to POSIX Make compatibility here. The
# automatic reconfigures are not too onerous, though, because they're
# much, much faster than Autotools configure runs.
#
# - Add target(s) to dump out specific vars, e.g. SQLITE_OPT, as
# requested at https://sqlite.org/forum/forumpost/75cb3179216f8d86.
# This would also be useful for the ext/wasm build, which fishes
# SHELL_OPT out of the makefile.
#
#
# Maintenance reminder: When using the X?=Y variable assignment
# formulation, please test the build with both GNU make and a POSIX
# make (e.g. BSD make, a.k.a. bmake). On at least one occassion, that
# formulation has led to inconsistent behavior between the two major
# make flavors when used with variable names which might sensibly be
# in the developer's environment (namely CC).

# JimTCL is part of the autosetup suite and is suitable for all
# current in-tree code-generation TCL jobs, but it requires that we
# build it with non-default flags. Note that the build tree will, if
# no system-level tclsh is found, also have a ./jimsh0 binary. That
# one is a bare-bones build for the configure process, whereas we need
# to build it with another option enabled for use with the various
# code generators.
#
# After jimsh is compiled, we run some sanity checks to ensure that
# it was built in a way compatible with this project's scripts:
#
# 1) Ensure that it was built with realpath() or _fullpath() support.
# Without that flag the [file normalize] command will always resolve
# to an empty string.
#
# 2) Ensure that it is built with -DJIM_COMPAT (which may be
# hard-coded into jimsh0.c). Without this, the [expr] command
# accepts only a single argument.
