This is used as a check to see if vcvars32.bat had been +# run prior to running nmake or during the installation of Microsoft +# Visual C++, MSVCDir had been set globally and the PATH adjusted. +# Either way is valid. +# +# You'll need to run vcvars32.bat contained in the MsDev's vc(98)/bin +# directory to setup the proper environment, if needed, for your +# current setup. This is a needed bootstrap requirement and allows the +# swapping of different environments to be easier. +# +# 2) To use the Platform SDK (not expressly needed), run setenv.bat after +# vcvars32.bat according to the instructions for it. This can also +# turn on the 64-bit compiler, if your SDK has it. +# +# 3) Targets are: +# release -- Builds the core, the shell and the dlls. (default) +# dlls -- Just builds the windows extensions +# shell -- Just builds the shell and the core. +# core -- Only builds the core [tclXX.(dll|lib)]. +# all -- Builds everything. +# test -- Builds and runs the test suite. +# tcltest -- Just builds the test shell. +# install -- Installs the built binaries and libraries to $(INSTALLDIR) +# as the root of the install tree. +# tidy/clean/hose -- varying levels of cleaning. +# genstubs -- Rebuilds the Stubs table and support files (dev only). +# depend -- Generates an accurate set of source dependancies for this +# makefile. Helpful to avoid problems when the sources are +# refreshed and you rebuild, but can "overbuild" when common +# headers like tclInt.h just get small changes. +# htmlhelp -- Builds a Windows .chm help file for Tcl and Tk from the +# troff manual pages found in $(ROOT)\doc. You need to +# have installed the HTML Help Compiler package from Microsoft +# to produce the .chm file. +# winhelp -- (deprecated) Builds the windows .hlp file for Tcl from +# the troff man files found in $(ROOT)\doc. This type of +# help file is deprecated by Microsoft in favour of html +# help files (.chm) +# +# 4) Macros usable on the commandline: +# INSTALLDIR=<path> +# Sets where to install Tcl from the built binaries. +# C:\Progra~1\Tcl is assumed when not specified. +# +# OPTS=loimpact,msvcrt,nothreads,pdbs,profile,static,staticpkg,symbols,thrdalloc,tclalloc,unchecked,none +# Sets special options for the core. The default is for none. +# Any combination of the above may be used (comma separated). +# 'none' will over-ride everything to nothing. +# +# loimpact = Adds a flag for how NT treats the heap to keep memory +# in use, low. This is said to impact alloc performance. +# msvcrt = Affects the static option only to switch it from +# using libcmt(d) as the C runtime [by default] to +# msvcrt(d). This is useful for static embedding +# support. +# nothreads= Turns off full multithreading support. +# pdbs = Build detached symbols for release builds. +# profile = Adds profiling hooks. Map file is assumed. +# static = Builds a static library of the core instead of a +# dll. The static library will contain the dde and reg +# extensions. External applications who want to use +# this, need to link with the stub library as well as +# the static Tcl library.The shell will be static (and +# large), as well. +# staticpkg = Affects the static option only to switch +# tclshXX.exe to have the dde and reg extension linked +# inside it. +# symbols = Debug build. Links to the debug C runtime, disables +# optimizations and creates pdb symbols files. +# thrdalloc = Use the thread allocator (shared global free pool) +# This is the default on threaded builds. +# tclalloc = Use the old non-thread allocator +# unchecked= Allows a symbols build to not use the debug +# enabled runtime (msvcrt.dll not msvcrtd.dll +# or libcmt.lib not libcmtd.lib). # -# Project directories +# STATS=compdbg,memdbg,none +# Sets optional memory and bytecode compiler debugging code added +# to the core. The default is for none. Any combination of the +# above may be used (comma separated). 'none' will over-ride +# everything to nothing. # -# ROOT = top of source tree +# compdbg = Enables byte compilation logging. +# memdbg = Enables the debugging memory allocator. # -# TOOLS32 = location of VC++ 32-bit development tools. Note that the -# VC++ 2.0 header files are broken, so you need to use the -# ones that come with the developer network CD's, or later -# versions of VC++. +# CHECKS=64bit,fullwarn,nodep,none +# Sets special macros for checking compatability. # -# TOOLS16 = location of VC++ 1.5 16-bit tools, needed to build thunking -# library. This information is optional; if the 16-bit compiler -# is not available, then the 16-bit code will not be built. -# Tcl will still run without the 16-bit code, but... -# A. Under Windows 3.X any calls to the exec command -# will return an error. -# B. A 16-bit program to test the behavior of the exec -# command under NT and 95 will not be built. -# INSTALLDIR = where the install- targets should copy the binaries and -# support files +# 64bit = Enable 64bit portability warnings (if available) +# fullwarn = Builds with full compiler and link warnings enabled. +# Very verbose. +# nodep = Turns off compatability macros to ensure the core +# isn't being built with deprecated functions. # +# MACHINE=(ALPHA|AMD64|IA64|IX86) +# Set the machine type used for the compiler, linker, and +# resource compiler. This hook is needed to tell the tools +# when alternate platforms are requested. IX86 is the default +# when not specified. If the CPU environment variable has been +# set (ie: recent Platform SDK) then MACHINE is set from CPU. +# +# TMP_DIR=<path> +# OUT_DIR=<path> +# Hooks to allow the intermediate and output directories to be +# changed. $(OUT_DIR) is assumed to be +# $(BINROOT)\(Release|Debug) based on if symbols are requested. +# $(TMP_DIR) will de $(OUT_DIR)\<buildtype> by default. +# +# TESTPAT=<file> +# Reads the tests requested to be run from this file. +# +# CFG_ENCODING=encoding +# name of encoding for configuration information.
