Tcl 8.5 for Windows
RCS: @(#) $Id: README,v 1.36 2007/12/14 20:56:20 hobbs 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.tcl.tk/doc/howto/compile.html#win
The above URL includes a lengthy discussion of compiler macros necessary
when compiling Tcl extensions that will be dynamically loaded.
2. Compiling Tcl
----------------
In order to compile Tcl for Windows, you need the following:
Tcl 8.5 Source Distribution (plus any patches)
and
Visual C++ 6 or newer
or
Msys + Mingw [http://www.mingw.org/download.shtml]
http://prdownloads.sourceforge.net/tcl/msys_mingw8.zip
This Msys + Mingw download above is the minimal environment needed
to build Tcl/Tk under Windows. It includes a shell environment and
gcc. The release is designed to make it as easy a possible to build
Tcl/Tk. To install, you just download the zip file and extract the
files into a directory. The README.TXT file describes how to launch
the msys shell, you then run the configure script in the tcl/win
directory.
In practice, this release is built with Visual C++ 6.0 and the TEA
Makefile.
If you are building with Visual C++, in the "win" subdirectory of the
source release, you will find "makefile.vc". This is the makefile for the
Visual C++ compiler and uses the stock NMAKE tool. Detailed directions for
using it, are in the comments of "makefile.vc". A quick example would be:
C:\tcl_source\win\>nmake -f makefile.vc
There is also a Developer Studio workspace and project file, too, if you
would like to use them.
If you are building with Msys or Cygwin, you can use the configure script
that lives in the win subdirectory. The Msys or Cygwin based
configure/build process works just like the UNIX one, so you will want to
refer to ../unix/README for available configure options. An error will be
generated by the configure script if you try to compile Tcl with the Cygwin
version of gcc instead of the Mingw version. Check your PATH if you get
this error. Be aware that gcc will generate lots of compile time warnings
when building Tcl. Warnings are not errors, so please don't file a bug
report about them.
Use the Makefile "install" target to install Tcl. It will install it
according to the prefix options you provided in the correct directory
structure.
Note that in order to run tclsh85.exe, you must ensure that tcl85.dll is on
your path, in the system directory, or in the directory containing
tclsh85.exe.
Note: Tcl no longer provides support for Win32s.
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 online database at
http://tcl.sourceforge.net/
In order to run the test suite, you build the "test" target using the
appropriate makefile for your compiler.
