## This file contains Automake rules common to many executables.

## This will instruct automake to create object files in the same
## directory as the corresponding source files, rather than in the
## top-level directory.  This is needed since some source files in tads2
## and tads3 have the same name.  Putting the object files in the same
## directory would cause the compiler to override some tads2 objects
## with tads3 objects of the same name.
##
## Note that this option requires the macro AM_PROG_CC_C_O to be used
## somewhere in configure.ac (since not all compilers can use the -c and
## -o options at the same time; different make-rules will be used if the
## compiler can't handle these options together).
##
AUTOMAKE_OPTIONS = subdir-objects

## These macros configure various parts of the base code.
##
##   FROBTADS
##     Tells the base code to include our osfrobtads.h header.  This
##     must be used in all executables.
##
##   VMGLOB_VARS
##     Tells the T3VM to use individual external variables for the
##     globals.  This is the fastest configuration.  (See tads3/vmglob.h
##     for details.)
##
##   VMGLOB_PARAM
##     Used in debug-builds of TADS 3 instead of VMGLOB_VARS.
##
##   VM_FLAT_POOL
##     Tells the T3VM to use the "flat" pool manager.  A flat pool is
##     somewhat faster than the default paged pool normaly used by the
##     VM, but lacks dynamic memory capabilites.  The paged pool is only
##     useful for debuggers though, so we choose a flat pool.  (See
##     tads3/vmpoolsl.h for details.)
##
##   TC_TARGET_T3
##     Instructs the TADS3 compiler to generate T3VM bytecode.  This is
##     also needed by the runtime, since it does dynamic compiling.
##
##   TADSNET
##     Include the T3 networking layer.
##
AM_CPPFLAGS = -DFROBTADS -DTC_TARGET_T3 -DTADSNET

if T3_DEBUG_BUILD
AM_CPPFLAGS += -DT3_DEBUG -DVMGLOB_PARAM
else
AM_CPPFLAGS += -DVMGLOB_VARS
endif

## Not yet; causes some (minor) memory leaks.  For now, only the paged
## pool is safe.
## AM_CPPFLAGS += -DVM_FLAT_POOL

## If the system is little-endian, define _M_IX86_64.  If not, we'll
## define _M_PPC.  The base code needs one of these macros defined, so
## that it can decide which version of some endian-dependent routines
## to use.
##
## Note that we define _M_IX86_64 instead of _M_IX86 even though the
## former is intended for 64-bit platforms.  The reason is that
## _M_IX86_64 works correctly even for 32-bit systems but not for
## 16-bit systems.  _M_IX86 works for 32-bit systems as well as for
## 16-bit systems but not for 64-bit systems.  Since we're only
## interested in 32 and 64-bit systems and don't support 16-bit systems
## at all, _M_IX86_64 is what we need.
##
## _M_PPC tells the base code to use the PowerPC versions of the
## endian-related routines.  Despite the name, the PowerPC versions of
## these routines are generic and useable by both big-endian as well as
## little-endian machines; they're just a little slower on x86 and
## x86-64 systems than the ones activated with _M_IX86(_64).
##
if CPU_IS_BIGENDIAN
  AM_CPPFLAGS += -D_M_PPC
else
  AM_CPPFLAGS += -D_M_IX86_64
endif

## If the user does not want the T2 VM to check for errors like stack
## overflows/underflows and such at runtime, define RUNFAST so that the
## base code disables these checks.
##
if !T2_RUNTIME_CHECKING
  AM_CPPFLAGS += -DRUNFAST
endif

## We need to tell the compiler where to find header files.  We prepend
## the source directory in case we are building the package in a
## different directory than the one it has been unpacked into.
##
AM_CPPFLAGS += -I$(top_srcdir)/src -I$(top_srcdir)/tads2 -I$(top_srcdir)/tads3 -I$(top_srcdir)/tads3/unix

## If the system lacks the wchar.h header, provide our own.
##
if WCHAR_HEADER_MISSING
  AM_CPPFLAGS += -I$(top_srcdir)/src/wchar
endif

## These are the paths of various TADS 3 data-files.  We need to know
## about them at runtime, so we also define them as macros.
##
T3_INC_DIR = $(pkgdatadir)/tads3/include
T3_LIB_DIR = $(pkgdatadir)/tads3/lib
T3_RES_DIR = $(pkgdatadir)/tads3/res

## This is not needed at runtime so we don't add it to AM_CPPFLAGS.
##
T3_CHARMAP_DIR = $(T3_RES_DIR)/charmap

## The TADS 3 character mapping tables are needed by both the
## interpreter as well as the compiler.  Automake allows us to install
## files only once though.  Normally, we would write something like
## "if BUILD_INTERPRETER or BUILD_T3_COMPILER", but Automake only allows
## a single conditional in 'if' statements.
##
if BUILD_INTERPRETER
t3charmapdir = $(T3_CHARMAP_DIR)

dist_t3charmap_DATA = tads3/charmap/cmaplib.t3r

## We need to make sure the Tads 2 compiler data files are always included in
## the "dist" target, regardless of whether the compiler is enabled or not.

## target.  Note that files like AUTHORS, README, etc. are automatically
## included in the distribution only if they're in the
## top-level directory.  Makefile fragments included from Makefile.am
## (such as this file) are also distributed automaticly.
