This directory also contains source files for Tcl that are +specific to UNIX. Some of the files in this directory are used on the PC or +MacOSX platform too, but they all depend on UNIX (POSIX/ANSI C) interfaces and +some of them only make sense under UNIX. + +Updated forms of the information found in this file is available at: + http://www.tcl.tk/doc/howto/compile.html#unix + +For information on platforms where Tcl is known to compile, along with any +porting notes for getting it to work on those platforms, see: + http://www.tcl.tk/software/tcltk/platforms.html + +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 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/unix/aclocal.m4 b/unix/aclocal.m4 new file mode 100644 index 0000000..90d2e39 --- /dev/null +++ b/unix/aclocal.m4 @@ -0,0 +1 @@ +builtin(include,../unix/tcl.m4) diff --git a/unix/configure b/unix/configure new file mode 100755 index 0000000..129c283 --- /dev/null +++ b/unix/configure @@ -0,0 +1,11611 @@ +#! /bin/sh +# Guess values for system-dependent variables and create Makefiles. +# Generated by GNU Autoconf 2.69 for tcl 8.7. +# +# +# Copyright (C) 1992-1996, 1998-2012 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 more Bourne compatible +DUALCASE=1; export DUALCASE # for MKS sh +if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then : + emulate sh + NULLCMD=: + # Pre-4.2 versions of Zsh do word splitting on ${1+"$@"}, which + # is contrary to our usage.
