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 rest of this file +contains information specific to the Windows version of Tcl. + +2. Distribution notes +--------------------- + +Tcl 8.0 for Windows is distributed in binary form in addition to the +common source release. The binary distribution is a self-extracting +archive with a built-in installation script. + +Look for the binary release in the same location as the source release +(ftp.smli.com:/pub/tcl or any of the mirror sites). For most users, +the binary release will be much easier to install and use. You only +need the source release if you plan to modify the core of Tcl, or if +you need to compile with a different compiler. With the addition of +the dynamic loading interface, it is no longer necessary to have the +source distribution in order to build and use extensions. + +3. Compiling Tcl +---------------- + +In order to compile Tcl for Windows, you need the following items: + + Tcl 8.0 Source Distribution (plus any patches) + + Borland C++ 4.52 (both 16-bit and 32-bit compilers) + or + Visual C++ 2.x/4.x + Visual C++ 1.5 (to build tcl1680.dll for Win32s support of exec) + +In the "win" subdirectory of the source release, you will find two +files called "makefile.bc" and "makefile.vc". These are the makefiles +for the Borland and Visual C++ compilers respectively. You should +copy the appropriate one to "makefile" and 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\tcl8.0 directory under the installation directory + as specified in the registry: + + For Windows NT & 95: + HKEY_LOCAL_MACHINE\SOFTWARE\Sun\Tcl\8.0 + Value Name is "Root" + + For Win32s: + HKEY_CLASSES_ROOT\SOFTWARE\Sun\Tcl\8.0\ + + 3) Relative to the directory containing the current .exe. + Tcl will look for a directory "..\lib\tcl8.0" relative to the + directory containing the currently running .exe. + +Note that in order to run tclsh80.exe, you must ensure that tcl80.dll +and tclpip80.dll (plus tcl1680.dll under Win32s) are on your path, in +the system directory, or in the directory containing tclsh80.exe. + +4. 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. + +In order to run the test suite, you build the "test" target using the +appropriate makefile for your compiler. + + +5. Known Bugs +------------- + +Here is the current list of known bugs/missing features for the +Windows version of Tcl: + +- Blocking "after" commands (e.g. "after 3000") don't work on Win32s. +- Clock command fails to handle daylight savings time boundaries for + things like "last week". +- Background processes aren't properly detached on NT. +- File events only work on sockets. +- Pipes/files/console/serial ports don't support nonblocking I/O. +- The library cannot be used by two processes at the same time under + Win32s. + +If you have comments or bug reports for the Windows version of Tcl, +please direct them to: + +Scott Stanton +scott.stanton@eng.sun.com + +or post them to the comp.lang.tcl newsgroup. |
