It supports all features of Stow with some extensions. XStow as GNU Stow, are programs for managing the installation of software packages, keeping them separate (/usr/local/stow/emacs vs. /usr/local/stow/perl, for example) while making them appear to be installed in the same place (/usr/local). Stow requires Perl. But what's on systems where no Perl is available, or not yet installed? I tried compiling Stow with perlcc, but it failed. For compiling XStow a C++ compiler and a system with a couple of POSIX functions are required. It does not depend on an interpreter. Static compilation eg.: for resque disks are possible. XStow installs packages in exact the same way like stow, so you even can start a Linux From Scratch installation with XStow and when Perl is running continue installation by using GNU Stow. *) Name The X in the name has nothing to do with X11 It simple stands for Extended Stow (... I think). *) Status: It works fine. *) Features: XStow generates Stow compatible symlinks. You can install a package with XStow and uninstall it with Stow. It also supports, the creation of symlinks with absolute path names, but this will brake compatibilty with Stow. *) automated stow directory detection *) automated traversable link detection (/usr/man is a link to /usr/share/man) *) Planned Features: If you have any other ideas send a mail to kingleo@gmx.at, or the xstow mailing list: xstow-general@lists.sourceforge.net *) Future * By default full Stow compatibilty should be obtained. But more features will be impemented. *) Why * Stow requires Perl. But what's on systems where is no Perl available, or not yet installed? I tried compiling Stow with perlcc, but it failed. This was the initial reason. * Stow lacks some features and I'm not very common with perl... So I implemented them in XStow. *) Static versions If you enable static compiling 3 binaries 'xstow', 'xstow-static' and 'xstow-stow' will be created. The 'xstow-static' version has no ncurses support and the binary is compiled statically. Some extensions in the 'xstow-stow' target are disabled. This results in a static replacement of GNU Stow, with less extensions and the binary is smaller than the xstow-static binary. If you are heaviliy using xstow it is recomended compiling these static versions, since you are using xstow like one of the base system tools. Upgrading the libc with a static xstow is no problem. *) Getting the binary smaller call ./configure --help and see which features can be disabled espacially the ncurses support is absolutely not required! An other way: $ make mini Will compile 2 binaries xstow-mini and xstow-mini-static This should work with a gcc compiler on linux and may work with other compilers on other systems. *) Libraries - ncurses For better --help screen support XStow uses the ncurses library. With the help of this library XStow uses the available width of the terminal it is running on. If you don't compile XStow with ncurses support, the terminal width will be guessed as 80 characters wide. So the ncurses support is absolutely not required. All other required libraries are builtin (by side the libc and libstdc++) - format (builtin, required) supports a kind of typesafe printf() if the NFORMAT is defined the complete typechecking code of Format will be skipped. Only a dummy version of Format will be used. This code will be untypesafe. This feature was implemented cause we expect that when your code is already clean and well tested no type checking is required any more. It's just code ready to be released. - LeoIni (builtin, optional) supports configuration file reading. The library is not absolute portable. It requires a GNU like STL. The configure script checks automatically if it can be used. - Arg (builtin, required) supports parsing of the command line, which can be a nitty gritty case. - CppDir (builtin, required) abstracts files and directories and provides some path manipulating functions. xstow-1.0.0/aclocal.m40000644000175000001440000010566111421646755011475 00000000000000# generated automatically by aclocal 1.11 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005, 2006, 2007, 2008, 2009 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.63],, [m4_warning([this file was generated for autoconf 2.63.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.
