Installation Instructions for GNU pspp ************************************** These instructions are based on the generic GNU installation instructions, but they have been tailored for PSPP. Overview ======== PSPP uses the standard GNU configuration system. Therefore, if all is well, the following simple procedure should work, even on non-GNU systems: tar -xzf pspp-*.tar.gz cd pspp-* ./configure make sudo make install Obviously, you should replace 'pspp-*' in the above, with the name of the tarball you are installing. If any part of this process fails, then it's likely that one or more of the necessary prerequisites is missing from your system. Read on to find out how to correct this. Before You Install ================== Before you install PSPP, you will need to install certain prerequisite packages. You may also want to install other packages that enable additional functionality in PSPP. If you do not know whether you have these installed already, you may proceed to "Basic Installation", below. The PSPP configuration process will notify you about required and optional packages that are not present on your system. The following packages are required to install PSPP: * An ANSI C compiler and tool chain. On Unix-like systems, we recommend GCC, but any modern compilation environment should work. On Microsoft Windows, Cygwin (http://www.cygwin.com/) and MinGW (http://www.mingw.org/) are known to work. * The GNU Scientific Library (http://www.gnu.org/software/gsl/), version 1.8 or later, including libgslcblas included with GSL. * Perl (http://www.perl.org/), version 5.005_03 or later. Perl is required during build but not after installation. * iconv, which should be installed as part of a Unix-like system. If you don't have a version already, you can install GNU libiconv (http://www.gnu.org/software/libiconv/). * libintl, from GNU gettext (http://ww.gnu.org/software/gettext). GNU libc includes an integrated libintl, so there is no need to separately install libintl on a GNU/Linux system. The following packages are required to enable PSPP's graphing features. If you cannot arrange to install them, you must run `configure' with --without-cairo. * Cairo (http://cairographics.org/), version 1.5 or later. * Pango (http://www.pango.org/), version 1.22 or later. The following packages are required to enable PSPPIRE, the graphical user interface for PSPP. If you cannot install them or do not wish to use the GUI, you must run `configure' with --without-gui. * pkg-config (http://pkg-config.freedesktop.org/wiki/). Versions 0.18 and 0.19 have a bug that will prevent library detection, but other versions should be fine. * GTK+ (http://www.gtk.org/), version 2.12.0 or later. * GtkSourceView (http://projects.gnome.org/gtksourceview/) version 2.2 or later. Installing the following packages will allow your PSPP binary to read Gnumeric files. * zlib (http://www.zlib.net/). * libxml2 (http://xmlsoft.org/). Installing the following packages will allow your PSPP binary to write OpenDocument text (ODT) files: * libxml2 (http://xmlsoft.org/). The following packages are optional. * libncurses (http://www.gnu.org/software/ncurses/). Without it, PSPP will assume it is running in an 80x25 terminal. * libreadline and libhistory (http://tiswww.case.edu/php/chet/readline/rltop.html). Without them, interactive command editing and history features in the text-based user interface will be disabled. * Texinfo (http://www.gnu.org/software/texinfo/), version 4.7 or later. Installing Texinfo will allow you to build PSPP documentation in PostScript or PDF format. * libpq, from Postgresql (http://postgresql.org). This enables PSPP to read Postgresql databases. The tests for the Postgresql interface, but not the Postgresql interface itself, requires the Postgresql server to be installed. * The Text::Diff module for Perl (http://cpan.org). This enables PSPP to test the Perl module more thoroughly. It is not needed to build or use the Perl module. Basic Installation ================== These are installation instructions specific to PSPP (including PSPPIRE, the graphic user interface). These instructions contain the information most commonly needed by people wishing to build the program from source. More detailed information can be found in the generic autoconf manual which is available at http://www.gnu.org/software/autoconf/manual/html_node/Running-configure-Scripts.html The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. If you need to do unusual things to compile the package, please report the problem to bug-gnu-pspp@gnu.org. We will try to figure out how `configure' could work better in your situation for the next release. The simplest way to compile PSPP is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. You may invoke `configure' with --help to see what options are available. The most common of these are listed under "Optional Features", below. It is best to build and install PSPP in directories whose names do not contain unusual characters such as spaces or single-quotes, due to limitations of the tools involved in the build process. If you installed some of the libraries that PSPP uses in a non-standard location (on many systems, anywhere other than /usr), you may need to provide some special flags to `configure' to tell it where to find them. For example, on GNU/Linux, if you installed some libraries in /usr/local, then you need to invoke it with at least the following options: ./configure LDFLAGS='-L/usr/local/lib -Wl,-rpath,/usr/local/lib' CPPFLAGS='-I/usr/local/include' Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. If `configure' completes successfully, it prints the message "PSPP configured successfully." at the end of its run. Otherwise, it may stop with a list of packages that you must install before PSPP. If it does, you need to install those packages, then re-run this step. Some prerequisites may be omitted by passing a --without- flag to `configure' (see "Optional Features", below). If you use one of these flags, then the feature that it disables will not be available in your PSPP installation. `configure' may also print a list of packages that you should consider installing. If you install them, then re-run `configure', additional features will be available in your PSPP installation. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run the self-tests that come with the package. If any of the self-tests fail, please mail bug-gnu-pspp@gnu.org with the details, to give the PSPP developers an opportunity to fix the problem in the next release. 4. Type `make install' to install the programs and any data files and documentation. Ordinarily you will need root permissions to do this. The "su" and "sudo" commands are common ways to obtain root permissions. If you cannot get root permissions, see "Installation Names", below. Please note: The `make install' target does NOT install the perl module (see below). To install the perl module, you must change to the `perl-module' directory and manually run `make install' there. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. Compilers and Options ===================== Some systems may require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix To cross-compile PSPP, you will likely need to set the PKG_CONFIG_LIBDIR environment variable to point to an appropriate pkg-config for the cross-compilation environment. See "Defining Variables", below, for more details. Installation Names ================== By default, `make install' installs PSPP's commands under `/usr/local/bin', data files under `/usr/local/share', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX'. You may wish to install PSPP on a machine where you do not have root permissions. To do so, specify a prefix relative within your home directory, e.g. `--prefix=$HOME' or `--prefix=$HOME/inst'. All PSPP files will be installed under the prefix directory, which `make install' will create if necessary. You may run PSPP directly from the `bin' directory under the prefix directory as, e.g., `~/inst/bin/pspp' under most shells, or for added convenience you can add the installation directory to your PATH by editing a shell startup file such as `.bashrc'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. You can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= `--without-cairo' Don't compile in support for charts (using Cairo and Pango). This is useful if your system lacks these libraries. `--without-gui' Don't build the PSPPIRE gui. Use this option if you only want to build the command line version of PSPP. Cairo and Pango required to build the GUI, so --without-cairo implies --without-gui. `--with-gui-tools' Build the gui developer tools. There is no reason to use this option unless you're involved with the development of PSPP `--without-lib{xx}' Optional libraries should normally be detected and the relevant functionality will be built they exist. However, on some poorly configured systems a library may exist, but be totally broken. In these cases you can use --without-lib{xx} to force configure to disregard it. `--without-perl-module' Disable building the Perl module, in case it does not build properly or you do not need it. `--enable-anachronistic-dependencies' If you use this option, some of the checks for dependent libraries will be relaxed, permitting configure to succeed when older versions of libraries are detected. Use of this option is not recommended. If you use it, some features may be missing and the build may fail with obscure error messages. `--enable-relocatable' This option is useful for building a package which can be installed into an arbitrary directory and freely copied to any other directory. If you use this option, you will probably want to install the pspp with a command similar to "make install DESTDIR=". Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Here is another example: /bin/bash ./configure CONFIG_SHELL=/bin/bash Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent configuration-related scripts to be executed by `/bin/bash'. Generic `configure' Options =========================== `configure' also recognizes the following options to control how it operates. `--help' `-h' Print a summary of the options to `configure', and exit. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. ---------------------------------------------------------------------- Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005, 2007 Free Software Foundation, Inc.
