- This is the directory where you configure, compile, test, and install
- UNIX versions of Tk. This directory also contains source files for Tk
- that are specific to UNIX.
-
- The rest of this file contains instructions on how to do this. The
- release should compile and run either "out of the box" or with trivial
- changes on any UNIX-like system that approximates POSIX, BSD, or System
- V. We know that it runs on workstations from Sun, H-P, DEC, IBM, and
- SGI, as well as PCs running Linux, BSDI, and SCO UNIX. To compile for
- a PC running Windows, see the README file in the directory ../win. To
- compile for a Macintosh, see the README file in the directory ../mac.

- How To Compile And Install Tk:
- ------------------------------
-
- (a) Make sure that the Tcl 7.5 release is present in the directory
- ../../tcl7.5. This release of Tk will only work with Tcl 7.5.
- Also, be sure that you have configured Tcl before you configure
- Tk.
-
- (b) Check for patches as described in ../README.
-
- (b) Type "./configure". This runs a configuration script created by GNU
- autoconf, which configures Tcl for your system and creates a
- Makefile. The configure script allows you to customize the Tcl
- configuration for your site; for details on how you can do this,
- type "./configure -help" or refer to the autoconf documentation (not
- included here). Note: Tk will use the same C compiler (e.g. gcc)
- as Tcl, as well as several other of Tcl's configuration options.
- You should not usually modify CC in the Makefile generated here
- (if do you, be sure to check all of the definitions related to dynamic
- loading to make sure that they are still correct). Tk's "configure"
- supports the following special switches in addition to the standard ones:
- --with-tcl=DIR Specifies the directory containing the Tcl
- binaries and Tcl's platform-dependent
- configuration information. By default
- the Tcl directory is assumed to be in the
- location given by (a) above.
- --enable-shared If this switch is specified, Tk will compile
- itself as a shared library if it can figure
- out how to do that on this platform.
- Note: be sure to use only absolute path names (those starting with "/")
- in the --prefix and --exec_prefix options.
-
- (d) Type "make". This will create a library archive called "libtk.a"
- or "libtk.so" and an interpreter application called "wish" that
- allows you to type Tcl commands interactively or execute script files.
-
- (e) If the make fails then you'll have to personalize the Makefile
- for your site or possibly modify the distribution in other ways.
- First check the file "porting.notes" to see if there are hints
- for compiling on your system. Then look at the porting Web page
- described later in this file. If you need to modify Makefile,
- there are comments at the beginning of it that describe the things
- you might want to change and how to change them.
-
- (f) Type "make install" to install Tk's binaries and script files in
- standard places. You'll need write permission on the installation
- directoryies to do this. The installation directories are
- determined by the "configure" script and may be specified with
- the --prefix and --exec_prefix options to "configure". See the
- Makefile for information on what directories were chosen; you
- can override these choices by modifying the "prefix" and
- "exec_prefix" variables in the Makefile.
-
- (g) At this point you can play with Tk by invoking the "wish"
- program and typing Tcl commands. However, if you haven't installed
- Tk then you'll first need to set your TK_LIBRARY environment
- variable to hold the full path name of the "library" subdirectory.
- If you haven't installed Tcl either then you'll need to set your
- TCL_LIBRARY environment variable as well (see the Tcl README file
- for information on this). Note that installed versions of wish,
- libtk.a, libtk.so, and the Tk library have a version number in their
- names, such as "wish4.0" or "libtk4.0.so"; to use the installed
- versions, either specify the version number or create a symbolic
- link (e.g. from "wish" to "wish4.0").
-
- If you have trouble compiling Tk, read through the file "porting.notes".
- It contains information that people have provided about changes they had
- to make to compile Tcl in various environments. Or, check out the
- following Web URL:
- http://www.sunlabs.com/cgi-bin/tcl/info.4.1
- This is an on-line database of porting information. We make no guarantees
- that this information is accurate, complete, or up-to-date, but you may
- find it useful. If you get Tk running on a new configuration and had to
- make non-trivial changes to do it, we'd be happy to receive new information
- to add to "porting.notes". You can also make a new entry into the
- on-line Web database. We're also interested in hearing how to change the
- configuration setup so that Tcl compiles on additional platforms "out of
- the box".
-
- Test suite
- ----------
-
- Tk has a substantial self-test suite, consisting of a set of scripts in
- the subdirectory "tests". To run the test suite just type "make test"
- in this directory. You should then see a printout of the test files
- processed. If any errors occur, you'll see a much more substantial
- printout for each error. In order to avoid false error reports, be sure
- to run the tests with an empty resource database (e.g., remove your
- .Xdefaults file or delete any entries starting with *). Also, don't
- try to do anything else with your display or keyboard whlie the tests
- are running, or you may get false violations. See the README file in
- the "tests" directory for more information on the test suite.
-
- If the test suite generates errors, most likely they are due to non-
- portable tests that are interacting badly with your system configuration.
- We are gradually eliminating the non-portable tests, but this release
- includes many new tests so there will probably be some portability
- problems. As long as the test suite doesn't core dump, it's probably
- safe to conclude that any errors represent portability problems in the
- test suite and not fundamental flaws with Tk.
-
- There are also a number of visual tests for things such as screen layout,
- Postscript generation, etc. These tests all have to be run manually and
- the results have to be verified visually. To run the tests, cd to the
- "tests" directory and run the script "visual". It will present a main
- window with a bunch of menus, which you can use to select various tests.
