Tcl 8.1 for Windows by Scott Stanton Scriptics Corporation scott.stanton@scriptics.com RCS: @(#) $Id: README,v 1.11 1999/04/24 01:46:54 stanton Exp $ 1. Introduction --------------- This is the directory where you configure and compile the Windows version of Tcl. This directory also contains source files for Tcl that are specific to Microsoft Windows. The information in this file is maintained on the web at: http://www.scriptics.com/support/howto/compile.html#win 2. Compiling Tcl ---------------- In order to compile Tcl for Windows, you need the following items: Tcl 8.1 Source Distribution (plus any patches) Visual C++ 2.x/4.x/5.x In practice, the 8.1 release is built with Visual C++ 5.0 In the "win" subdirectory of the source release, you will find "makefile.vc". This is the makefile Visual C++ compiler. You should update the paths at the top of the file to reflect your system configuration. Now you can use "make" (or "nmake" for VC++) to build the tcl libraries and the tclsh executable. In order to use the binaries generated by these makefiles, you will need to place the Tcl script library files someplace where Tcl can find them. Tcl looks in one of three places for the library files: 1) The path specified in the environment variable "TCL_LIBRARY". 2) In the lib\tcl8.1 directory under the installation directory as specified in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Scriptics\Tcl\8.1 3) Relative to the directory containing the current .exe. Tcl will look for a directory "..\lib\tcl8.1" relative to the directory containing the currently running .exe. Note that in order to run tclsh81.exe, you must ensure that tcl81.dll and tclpip81.dll are on your path, in the system directory, or in the directory containing tclsh81.exe. Note: Tcl no longer provides support for Win32s. For more information about Compiling Tcl on Windows, please see http://www.scriptics.com/support/howto/compile.html#win This page includes a lengthy discussion of compiler macros necessary when compiling Tcl extensions that will be dynamically loaded. 3. Test suite ------------- This distribution contains an extensive test suite for Tcl. Some of the tests are timing dependent and will fail from time to time. If a test is failing consistently, please send us a bug report with as much detail as you can manage. Please use the form at http://www.scriptics.com/support/bugForm.html In order to run the test suite, you build the "test" target using the appropriate makefile for your compiler.
