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 MacOSX, see the README file in -the directory ../macosx. - -How To Compile And Install Tcl: -------------------------------- - -(a) If you have already compiled Tcl once in this directory and are now - preparing to compile again in the same directory but for a different - platform, or if you have applied patches, type "make distclean" to discard - all the configuration information computed previously. - -(b) If you need to reconfigure because you changed any of the .in or .m4 - files, you will need to run autoconf to create a new ./configure script. - Most users will NOT need to do this since a configure script is already - provided. - - (in the tcl/unix directory) - autoconf - -(c) 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). Tcl's "configure" - supports the following special switches in addition to the standard ones: - - --enable-threads If this switch is set, Tcl will compile itself - with multithreading support. - --disable-load If this switch is specified then Tcl will - configure itself not to allow dynamic loading, - even if your system appears to support it. - Normally you can leave this switch out and Tcl - will build itself for dynamic loading if your - system supports it. - --disable-dll-unloading Disables support for the [unload] command even - on platforms that can support it. Meaningless - when Tcl is compiled with --disable-load. - --enable-shared If this switch is specified, Tcl will compile - itself as a shared library if it can figure - out how to do that on this platform. This is - the default on platforms where we know how to - build shared libraries. - --disable-shared If this switch is specified, Tcl will compile - itself as a static library. - --enable-symbols Build with debugging symbols. By default - standard debugging symbols are used. You can - specify the value "mem" to include - TCL_MEM_DEBUG memory debugging, "compile" to - include TCL_COMPILE_DEBUG debugging, or "all" - to enable all internal debugging. - --disable-symbols Build without debugging symbols - --enable-64bit Enable 64bit support (where applicable) - --disable-64bit Disable 64bit support (where applicable) - --enable-64bit-vis Enable 64bit Sparc VIS support - --disable-64bit-vis Disable 64bit Sparc VIS support - --enable-langinfo Allows use of modern nl_langinfo check for - better localization support. This is on by - default on platforms where nl_langinfo is - found. - --disable-langinfo Specifically disables use of nl_langinfo. - --enable-man-symlinks Use symlinks for linking the manpages that - should be reachable under several names. - --enable-man-suffix[=STRING] - Append STRING to the names of installed manual - pages (prior to applying compression, if that - is also enabled). If STRING is omitted, - defaults to 'tcl'. - --enable-man-compression=PROG - Compress the manpages using PROG. - --enable-dtrace Enable tcl DTrace provider (if DTrace is - available on the platform), c.f. tclDTrace.d - for descriptions of the probes made available, - see http://wiki.tcl.tk/DTrace for more details - --with-encoding=ENCODING Specifies the encoding for compile-time - configuration values. Defaults to iso8859-1, - which is also sufficient for ASCII. - --with-tzdata=FLAG Specifies whether to install timezone data. By - default, the configure script tries to detect - whether a usable timezone database is present - on the system already. - - Mac OS X only (i.e. completely unsupported on other platforms): - - --enable-framework Package Tcl as a framework. - --disable-corefoundation Disable use of CoreFoundation API and revert - to standard select based notifier, required - when using naked fork (i.e. not followed by - execve). - - Note: by default gcc will be used if it can be located on the PATH. If you - want to use cc instead of gcc, set the CC environment variable to "cc" - before running configure. It is not safe to edit the Makefile to use gcc - after configure is run. Also note that you should use the same compiler - when building extensions. - - 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 "libtcl<version>.a" - or "libtcl<version>.so" and an interpreter application called "tclsh" that - allows you to type Tcl commands interactively or execute script files. It - will also create a stub library archive "libtclstub<version>.a" that - developers may link against other C code to produce loadable extensions - for Tcl. - -(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 - porting Web page above to see if there are hints for compiling on your - system. 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 Tcl binaries and script files in standard - places. You'll need write permission on the installation directories to do - this. The installation directories are determined by the "configure" - script and may be specified with the standard --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. The installed - binaries have embedded within them path values relative to the install - directory. If you change your mind about where Tcl should be installed, - start this procedure over again from step (a) so that the path embedded in - the binaries agrees with the install location. - -(g) At this point you can play with Tcl by running the installed "tclsh" - executable, or via the "make shell" target, and typing Tcl commands at the - interactive prompt. - -If you have trouble compiling Tcl, see the URL noted above about working -platforms. It contains information that people have provided about changes -they had to make to compile Tcl in various environments. 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 ----------- - -There is a relatively complete test suite for all of the Tcl core in the -subdirectory "tests". To use it 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. See the README -file in the "tests" directory for more information on the test suite. Note: -don't run the tests as superuser: this will cause several of them to fail. If -a test is failing consistently, please send us a bug report with as much -detail as you can manage to our tracker: - - http://core.tcl.tk/tcl/reportlist - diff --git a/tcl8.6/unix/aclocal.m4 b/tcl8.6/unix/aclocal.m4 deleted file mode 100644 index 90d2e39..0000000 --- a/tcl8.6/unix/aclocal.m4 +++ /dev/null @@ -1 +0,0 @@ -builtin(include,../unix/tcl.m4) diff --git a/tcl8.6/unix/configure b/tcl8.6/unix/configure deleted file mode 100755 index 38c3f9a..0000000 --- a/tcl8.6/unix/configure +++ /dev/null @@ -1,20272 +0,0 @@ -#! /bin/sh -# Guess values for system-dependent variables and create Makefiles. -# Generated by GNU Autoconf 2.59 for tcl 8.6. -# -# Copyright (C) 2003 Free Software Foundation, Inc. -# This configure script is free software; the Free Software Foundation -# gives unlimited permission to copy, distribute and modify it. -## --------------------- ## -## M4sh Initialization. ## -## --------------------- ## - -# Be Bourne compatible -if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then - emulate sh - NULLCMD=: - # Zsh 3.x and 4.x performs word splitting on ${1+"$@"}, which - # is contrary to our usage.
