# This file is a Makefile for Tcl.  If it has the name "Makefile.in"
# then it is a template for a Makefile;  to generate the actual Makefile,
# run "./configure", which is a configuration script generated by the
# "autoconf" program (constructs like "@[email protected]" will get replaced in the
# actual Makefile.

# The following target can only be used for non-patch releases.  Use
# the "allpatch" target below for patch releases.

alldist: dist

#
# The target below is similar to "alldist" except it works for patch
# releases.  It is needed because patch releases are peculiar: the
# patch designation appears in the name of the compressed file
# (e.g. tcl8.0p1.tar.gz) but the extracted source directory doesn't
# include the patch designation (e.g. tcl8.0).
#

#
# This target creates the HTML folder for Tcl & Tk and places it
# in DISTDIR/html.  It uses the tcltk-man2html.tcl tool from

# TOOL_DIR.

# Target to create a Macintosh version of the distribution.  This will

# Targets to build Solaris package of the distribution for the current
# architecture.  To build stream packages for both sun4 and i86pc
# architectures: 
#
#   On the sun4 machine, execute the following:
#     make distclean; ./configure
#     make DISTDIR=<distdir> package
#
#   Once the build is complete, execute the following on the i86pc
#   machine:
#     make DISTDIR=<distdir> package-quick
#
# <distdir> is the absolute path to a directory where the build should
# take place.  These steps will generate the $(PACKAGE).sun4 and
# $(PACKAGE).i86pc stream packages.  It is important that the packages be
# built in this fashion in order to ensure that the architecture
# independent files are exactly the same, including timestamps, in
# both packages.

Tcl UNIX README
---------------

This is the directory where you configure, compile, test, and install
UNIX versions of Tcl.  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 Mac 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://dev.scriptics.com/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://dev.scriptics.com/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 a Macintosh, see the README file in the directory ../mac.

How To Compile And Install Tcl:
-------------------------------

(a) Check for patches as described in ../README.

(b) 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.

(c) If there is no "configure" script in this directory it is because you
    are working out of the source repository (i.e., CVS) instead of working
    from a source distribution.  In this case you need to use "autoconf"
    to generate the configure script.  It runs with no arguments.
    Remember to run it here and down in the dltest directory.

    (in the tcl/unix directory)
    autoconf
    cd dltest ; autoconf ; cd ..

(d) 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-gcc		If this switch is set, Tcl will configure
				itself to use gcc if it is available on your
				system.  Note:  it is not safe to modify the
				Makefile to use gcc after configure is run;
				if you do this, then information related to
				dynamic linking will be incorrect.
	--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.
	--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.
    Note: be sure to use only absolute path names (those starting with "/")
    in the --prefix and --exec_prefix options.

(e) 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.

(f) 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,
    are comments at the beginning of it that describe the things you
    might want to change and how to change them.

(g) 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 --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.

(h) At this point you can play with Tcl by invoking the "tclsh"
    program and typing Tcl commands.  However, if you haven't installed
    Tcl then you'll first need to set your TCL_LIBRARY variable to
    hold the full path name of the "library" subdirectory.  Note that
    the installed versions of tclsh, libtcl.a, and libtcl.so have a
    version number in their names, such as "tclsh8.3" or "libtcl8.3.so";
    to use the installed versions, either specify the version number
    or create a symbolic link (e.g. from "tclsh" to "tclsh8.3").

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.  Please use the online database at
	http://dev.scriptics.com/ticket/

The Tcl test suite is very sensitive to proper implementation of
ANSI C library procedures such as sprintf and sscanf.  If the test
suite generates errors, most likely they are due to non-conformance
of your system's ANSI C library;  such problems are unlikely to
affect any real applications so it's probably safe to ignore them.

#	1. Use "connect" and "accept" to check for -lsocket, and

#	2. Use each function name only once:  can't redo a check because
#	   autoconf caches the results of the last check and won't redo it.
#	3. Use -lnsl and -lsocket only if they supply procedures that
#	   aren't already present in the normal libraries.  This is because
#	   IRIX 5.2 has libraries, but they aren't needed and they're
#	   bogus:  they goof up name resolution if used.
#	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
#	   To get around this problem, check for both libraries together
#	   if -lsocket doesn't work by itself.

This directory contains several files for testing Tcl's dynamic
loading capabilities.  If this directory is present and the files
in here have been compiled, then the "load" test will use the shared
libraries present here to run a series of tests.  To compile the
shared libraries, first type "./configure".  This will read
configuration information created when Tcl was configured and
create Makefile from Makefile.in.  Be sure that you have configured
Tcl before configuring here, since information learned during Tcl's
configure is needed here.  Then type "make" to create the shared
libraries.

# 1. Nm produces different output under AIX 4.1 than under AIX 3.2.5;
#    the following statements handle both versions.
# 2. Use the -g switch to nm instead of -e under 4.1 (this shows just
#    externals, not statics;  -g isn't available under 3.2.5, though).
# 3. Eliminate lines that end in ":": these are the names of object
#    files (relevant in 4.1 only).
# 4. Eliminate entries with the "U" key letter;  these are undefined
#    symbols (relevant in 4.1 only).
# 5. Eliminate lines that contain the string "0|extern" preceded by space;
#    in 3.2.5, these are undefined symbols (address 0).
# 6. Eliminate lines containing the "unamex" symbol.  In 3.2.5, these
#    are also undefined symbols.
# 7. If a line starts with ".", delete the leading ".", since this will
#    just cause confusion later.
# 8. Eliminate everything after the first field in a line, so that we're
#    left with just the symbol name.

# This script is invoked when installing manual entries.  It generates
# additional links to manual entries, corresponding to the procedure
# and command names described by the manual entry.  For example, the
# Tcl manual entry Hash.3 describes procedures Tcl_InitHashTable,
# Tcl_CreateHashEntry, and many more.  This script will make hard
# links so that Tcl_InitHashTable.3, Tcl_CreateHashEntry.3, and so
# on all refer to Hash.3 in the installed directory.
#
# Because of the length of command and procedure names, this mechanism
# only works on machines that support file names longer than 14 characters.
# This script checks to see if long file names are supported, and it
# doesn't make any links if they are not.
#
# The script takes one argument, which is the name of the directory
# where the manual entries have been installed.

# This script is invoked when installing manual entries.  It generates
# additional links to manual entries, corresponding to the procedure
# and command names described by the manual entry.  For example, the
# Tcl manual entry Hash.3 describes procedures Tcl_InitHashTable,
# Tcl_CreateHashEntry, and many more.  This script will make hard
# links so that Tcl_InitHashTable.3, Tcl_CreateHashEntry.3, and so
# on all refer to Hash.3 in the installed directory.
#
# Because of the length of command and procedure names, this mechanism
# only works on machines that support file names longer than 14 characters.
# This script checks to see if long file names are supported, and it
# doesn't make any links if they are not.
#
# The script takes one argument, which is the name of the directory
# where the manual entries have been installed.

#
#       DL_OBJS -       Name of the object file that implements dynamic
#                       loading for Tcl on this system.
#       DL_LIBS -       Library file(s) to include in tclsh and other base
#                       applications in order for the "load" command to work.
#       LDFLAGS -      Flags to pass to the compiler when linking object
#                       files into an executable application binary such
#                       as tclsh.
#       LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
#                       that tell the run-time dynamic linker where to look
#                       for shared libraries such as libtcl.so.  Depends on
#                       the variable LIB_RUNTIME_DIR in the Makefile.
#       MAKE_LIB -      Command to execute to build the Tcl library;
#                       differs depending on whether or not Tcl is being
#                       compiled as a shared library.
#       SHLIB_CFLAGS -  Flags to pass to cc when compiling the components
#                       of a shared library (may request position-independent
#                       code, among other things).
#       SHLIB_LD -      Base command to use for combining object files
#                       into a shared library.
#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
#                       creating shared libraries.  This symbol typically
#                       goes at the end of the "ld" commands that build
#                       shared libraries. The value of the symbol is
#                       "${LIBS}" if all of the dependent libraries should
#                       be specified when creating a shared library.  If
#                       dependent libraries should not be specified (as on
#                       SunOS 4.x, where they cause the link to fail, or in
#                       general if Tcl and Tk aren't themselves shared
#                       libraries), then this symbol has an empty string
#                       as its value.
#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
#                       extensions.  An empty string means we don't know how
#                       to use shared libraries on this platform.
#       TCL_LIB_FILE -  Name of the file that contains the Tcl library, such
#                       as libtcl7.8.so or libtcl7.8.a.
#       TCL_LIB_SUFFIX -Specifies everything that comes after the "libtcl"
#                       in the shared library name, using the $VERSION variable
#                       to put the version in the right place.  This is used
#                       by platforms that need non-standard library names.
#                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
#                       to have a version after the .so, and ${VERSION}.a
#                       on AIX, since the Tcl shared library needs to have
#                       a .a extension whereas shared objects for loadable
#                       extensions have a .so extension.  Defaults to
#                       ${VERSION}${SHLIB_SUFFIX}.
#       TCL_NEEDS_EXP_FILE -
#                       1 means that an export file is needed to link to a
#                       shared library.
#       TCL_EXP_FILE -  The name of the installed export / import file which
#                       should be used to link to the Tcl shared library.
#                       Empty if Tcl is unshared.
#       TCL_BUILD_EXP_FILE -
#                       The name of the built export / import file which
#                       should be used to link to the Tcl shared library.
#                       Empty if Tcl is unshared.

Summary: Tcl scripting language development environment
Name: tcl
Version: %{version}
Release: 1
Copyright: BSD
Group: Development/Languages
Source: ftp://ftp.scriptics.com/pub/tcl/tcl8_3/tcl%{version}.tar.gz

%description
The Tcl (Tool Command Language) provides a powerful platform for
creating integration applications that tie together diverse
applications, protocols, devices, and frameworks.  When paired with
the Tk toolkit, Tcl provides the fastest and most powerful way to
create GUI applications that run on PCs, Unix, and the Macintosh.  Tcl
can also be used for a variety of web-related tasks and for creating
powerful command languages for applications.

# to create the tcl files list, comment out tk in the install section above,
# then run "rpm -bi" then do a find from the build root directory,
# and remove the files in specific directories which suffice by themselves,
# then to create the files list for tk, uncomment tk, comment out tcl,
# then rm -rf $RPM_BUILD_ROOT then rpm --short-circuit -bi then redo a find,
# and remove the files in specific directories which suffice by themselves.

 * TclpLoadFile --

 *
 * Results:
 *	A standard Tcl completion code.  If an error occurs, an error
 *	message is left in the interp's result.  *proc1Ptr and *proc2Ptr
 *	are filled in with the addresses of the symbols given by
 *	*sym1 and *sym2, or NULL if those symbols can't be found.
 *
 * Side effects:
 *	New code suddenly appears in memory.
 *
 *
 * Bugs:
 *	This function does not attempt to handle the case where the
 *	BSS segment is not executable.  It will therefore fail on
 *	Encore Multimax, Pyramid 90x, and similar machines.  The
 *	reason is that the mprotect() kernel call, which would
 *	otherwise be employed to mark the newly-loaded text segment
 *	executable, results in a system crash on BSD/386.
 *
 *	In an effort to make it fast, this function eschews the
 *	technique of linking the load module once, reading its header
 *	to determine its size, allocating memory for it, and linking
 *	it again.  Instead, it `shims out' memory allocation by
 *	placing the module TCL_LOADSHIM bytes beyond the break,
 *	and assuming that any malloc() calls required to run the
 *	linker will not advance the break beyond that point.  If
 *	the break is advanced beyonnd that point, the load will
 *	fail with an `inconsistent memory allocation' error.
 *	It perhaps ought to retry the link, but the failure has
 *	not been observed in two years of daily use of this function.

/* 
 * tclLoadOSF.c --
 *
 *	This procedure provides a version of the TclLoadFile that works
 *	under OSF/1 1.0/1.1/1.2 and related systems, utilizing the old OSF/1
 *	/sbin/loader and /usr/include/loader.h.  OSF/1 versions from 1.3 and
 *	on use ELF, rtld, and dlopen()[/usr/include/ldfcn.h].
 *
 *	This is useful for:
 *		OSF/1 1.0, 1.1, 1.2 (from OSF)
 *			includes: MK4 and AD1 (from OSF RI)
 *		OSF/1 1.3 (from OSF) using ROSE
 *		HP OSF/1 1.0 ("Acorn") using COFF
 *
 *	This is likely to be useful for:
 *		Paragon OSF/1 (from Intel) 
 *		HI-OSF/1 (from Hitachi) 
 *
 *	This is NOT to be used on:
 *		Digitial Alpha OSF/1 systems
 *		OSF/1 1.3 or later (from OSF) using ELF
 *			includes: MK6, MK7, AD2, AD3 (from OSF RI)
 *
 *	This approach to things was utter @&^#; thankfully,
 * 	OSF/1 eventually supported dlopen().

     * were passed to the OS, without translating from UTF-8 to native,
     * because the name was already in the native encoding.
     *
     * Now that the system encoding was actually successfully set,
     * translate all the names in the library path to UTF-8.  That way,
