! 2:
! 3: \section{Required tools}
! 4:
! 5: We assume that you have either an \kbd{ANSI C} or a \kbd{C++} compiler
! 6: available. If your machine does not have one (for example if you still use
! 7: \kbd{/bin/cc} in \kbd{SunOS 4.1.x}), we strongly suggest that you obtain the
! 8: \kbd{gcc/g++} compiler from the Free Software Foundation or by
! 9: anonymous~\kbd{ftp}. As for all GNU software mentioned afterwards, you can
! 10: find the most convenient site to fetch \kbd{gcc} at the address
! 11:
! 12: \kbd{http://www.gnu.ai.mit.edu/order/ftp.html}
! 13:
! 14: \noindent
! 15: You can certainly compile PARI with a different compiler, but the PARI
! 16: kernel takes advantage of some optimizations provided by \kbd{gcc} if it is
! 17: available. This results in about 20\% speedup on most architectures%
! 18: \footnote*{One notable exception is the native AIX C compiler on IBM
! 19: RS/6000 workstations, which generates fast code even without any special
! 20: help from the PARI kernel sources.}.
! 21:
! 22: \misctitle{Important Note:} The graphic routines in the present version have
! 23: only been tested under \kbd{X11} and \kbd{gnuplot}, and may not work at all
! 24: if you try to compile GP with an old \kbd{Suntools} library (even though this
! 25: is supposedly supported, nobody has tested it yet!!!).
! 26:
! 27: \subsec{Optional packages:} The following programs and libraries are useful
! 28: in conjunction with GP, but not mandatory. They're probably already installed
! 29: somewhere on your system (with the possible exception of \kbd{readline},
! 30: which we think is really worth a try). In any case, get them before
! 31: proceeding if you want the functionalities they provide. All of them are free
! 32: (though you ought to make a small donation to the FSF if you use (and like)
! 33: GNU wares).
! 34:
! 35: $\bullet$ GNU \kbd{readline} library. This provides line editing under GP,
! 36: an automatic context-dependent completion, and an editable history of
! 37: commands. Note that it is incompatible with SUN commandtools (yet another
! 38: reason to dump Suntools for X Windows). A recent readline (version number at
! 39: least 2.2) is preferred, but older versions should be usable.
! 40:
! 41: $\bullet$ GNU \kbd{gzip/gunzip/gzcat} package enables GP to read
! 42: compressed data.
! 43:
! 44: $\bullet$ GNU \kbd{emacs}. GP can be run in an Emacs buffer, with all the
! 45: obvious advantages if you are familiar with this editor. Note that
! 46: \kbd{readline} is still useful in this case since it provides a much better
! 47: automatic completion than is provided by Emacs GP-mode.
! 48:
! 49: $\bullet$ \kbd{perl} provides extended online help (full text from
! 50: Chapter~3) about functions and concepts, which can be used under GP or
! 51: independently (\kbd{http://www.perl.com} will direct you to the nearest
! 52: \kbd{CPAN} archive site).
! 53:
! 54: $\bullet$ A colour-capable \kbd{xterm}, which enables GP to use different
! 55: (user configurable) colours for its output. All \kbd{xterm} programs which come
! 56: with current X11R6.3 distributions will satisfy this requirement. Under X11R6,
! 57: you can for instance use \kbd{color\_xterm} (get the latest version at
! 58: \kbd{http://www.clark.net/pub/dickey/xterm}).
! 59:

! 61: \section{Compiling the library and the GP calculator}
! 62:
! 63: \subsec{Basic configuration:} First, have a look at the \kbd{MACHINES} file
! 64: to see if anything funny applies to your architecture or operating system.
! 65: Then, type
! 66:
! 67: \kbd{./Configure}
! 68:
! 69: \noindent in the toplevel directory. This will attempt to configure GP/PARI
! 70: without outside help. Note that if you want to install the end product in
! 71: some nonstandard place, you can use the \kbd{--prefix} option, as in
! 72:
! 73: \kbd{./Configure --prefix=/an/exotic/directory}
! 74:
! 75: \noindent (the default prefix is \kbd{/usr/local}). This phase extracts some
! 76: files and creates a directory \kbd{O$xxx$} where the object files and
! 77: executables will be built. The $xxx$ part depends on your architecture and
! 78: operating system, thus you can build GP for several different machines from
! 79: the same source tree (the builds are completely independent, so can be done
! 80: simultaneously).
! 81:
! 82: \noindent \kbd{Configure} will let the following environment variable
! 83: override the defaults if set:
! 84:
! 85: \kbd{AS}: Assembler.
! 86:
! 87: \kbd{CC}: C compiler.
! 88:
! 89: \kbd{DLLD}: Dynamic library linker.
! 90:
! 91: \noindent For instance, \kbd{Configure} avoids \kbd{gcc} on some
! 92: architectures due to various problems which may have been fixed in your
! 93: version of the compiler. You can try
! 94:
! 95: \kbd{env CC=gcc Configure}
! 96:
! 97: \noindent and compare the benches. Also, if you run into trouble with
! 98: a recent \kbd{g++}, try to use \kbd{g++ -fpermissive}.
! 99:
! 100: \subsec{Troubleshooting and fine tuning:} Decide whether you agree with what
! 101: \kbd{Configure} printed on your screen (in particular the architecture,
! 102: compiler and optimization flags). If anything should have been found and was
! 103: not, consider that \kbd{Configure} failed and follow the instructions below.
! 104: Look especially for the \kbd{readline} and \kbd{X11} libraries, and the
! 105: \kbd{perl} and \kbd{gunzip} (or \kbd{zcat}) binaries.
! 106:
! 107: In case the default \kbd{Configure} run fails miserably, try
! 108:
! 109: \kbd{./Configure -a}
! 110:
! 111: \noindent (interactive mode) and answer all the questions (there aren't that
! 112: many). Of course, \kbd{Configure} will still provide defaults for each answer
! 113: but if you accept them all, it will fail just the same, so be wary. In any
! 114: case, we would appreciate a bug report including the complete output from
! 115: \kbd{Configure} and the file \kbd{O$xxx$/dft.Config.in} that was produced in
! 116: the process.
! 117:
! 118: Note that even in interactive mode, you can't directly tell \kbd{Configure}
! 119: where the \kbd{readline} library and include files are. If they are not in a
! 120: standard place, it won't find them. Nonetheless, it first searches the
! 121: distribution toplevel for a \kbd{readline} directory. Thus, if you just want
! 122: to give \kbd{readline} a try (as you probably should), you can get the source
! 123: and compile it there (you don't need to install it). You can also use this
! 124: feature together with a symbolic link, named \kbd{readline}, in the PARI
! 125: toplevel directory if you have compiled the readline library somewhere else,
! 126: without installing it to one of its standard locations.
! 127:
! 128: \misctitle{Technical note:} Configure can build GP on different architectures
! 129: simultaneously from the same toplevel sources. Instead of the \kbd{readline}
! 130: link alluded above, you can create \kbd{readline-{\sl osname}-{\sl arch}},
! 131: using the same naming conventions as for the \kbd{O$xxx$} directory,
! 132: e.g \kbd{readline-linux-i686}.
! 133:
! 134: \subsec{Debugging/profiling}: If you also want to debug the PARI library,
! 135:
! 136: \kbd{Configure -g}
! 137:
! 138: \noindent will create a directory \kbd{O$xxx$.dbg} containing a special
! 139: \kbd{Makefile} ensuring that suitably non-optimized GP and PARI library will
! 140: be built there. If you want to profile GP or the library (using \kbd{gprof}
! 141: for instance),
! 142:
! 143: \kbd{Configure -pg}
! 144:
! 145: \noindent will create an \kbd{O$xxx$.prf} directory where a suitable version
! 146: of PARI can be built.
! 147:
! 148: \subsec{Compilation and tests:} To compile the GP binary, simply type
! 149:
! 150: \kbd{make gp}
! 151:
! 152: \noindent in the distribution directory. If your \kbd{make} program supports
! 153: parallel make, you can speed up the process by going to the \kbd{O$xxx$}
! 154: directory that \kbd{Configure} created and doing a parallel make here (for
! 155: instance \kbd{make -j4} with GNU make).
! 156:
! 157: \subsubsec{Testing}
! 158:
! 159: To test the binary, type \kbd{make bench}. This will build a static
! 160: executable (the default, built by \kbd{make gp} is probably dynamic) and
! 161: run a series of comparative tests on those two. To test only the default
! 162: binary, use \kbd{make dobench} which starts the bench immediately.
! 163:
! 164: The static binary should be slightly faster. In any case, this should not
! 165: take more than one minute (user time) on modern machines. See the file
! 166: \kbd{MACHINES} to get an idea of how much time comparable systems need (we
! 167: would appreciate a short note in the same format in case your system is not
! 168: listed and you nevertheless have a working GP executable).
! 169:
! 170: If a \kbd{[BUG]} message shows up, it probably means that something is wrong.
! 171: Most probably with the installation procedure, but it may be a bug in the
! 172: Pari system, in which case we would appreciate a report (including the
! 173: relevant \kbd{*.dif} file in the \kbd{O$xxx$} directory and the file
! 174: \kbd{dft.Config.in}). Error messages of the form ``not yet available for this
! 175: architecture'' are an obvious special case which should not trigger a bug
! 176: report (unless you implement the functionality yourself, that is!).
! 177:
! 178: \misctitle{Note:} If when running \kbd{gp-dyn}, you get a message of the form
! 179:
! 180: \kbd{ld.so: warning: libpari.so.$xxx$ has older revision than expected $xxx$}
! 181:
! 182: \noindent (possibly followed by more errors), you already have a dynamic PARI
! 183: library installed {\it and\/} a broken local configuration. Either remove the
! 184: old library or unset the \kbd{LD\_LIBRARY\_PATH} environment variable. Try to
! 185: disable this variable in any case if anything {\it very} wrong occurs with
! 186: the \kbd{gp-dyn} binary (e.g Illegal Instruction on startup). It doesn't
! 187: affect \kbd{gp-sta}.
! 188:
! 189: \subsubsec{Some more testing} [{\sl Optional\/}]
! 190:
! 191: You can test GP in compatibility mode with \kbd{make test-compat}. If you
! 192: want to test the graphic routines, use \kbd{make test-graphic}. You will
! 193: have to click on the mouse button after seeing each image (under X11; under
! 194: suntools you must kill the images). There will be eight of them, probably
! 195: shown twice (under X11, try to resize at least one of them as a further
! 196: test).
! 197:
! 198: The \kbd{make bench} and \kbd{make test-compat} runs produce a Postscript
! 199: file \kbd{pari.ps} in \kbd{O$xxx$} which you can send to a Postscript
! 200: printer. The output should bear some similarity to the screen images.
! 201:
! 202: \section{Installation} When everything looks fine, type
! 203:
! 204: \kbd{make install}
! 205:
! 206: \noindent (You may have to do this with superuser privileges, depending on
! 207: the target directories.) Beware that, if you chose the same installation
! 208: directory as before in the \kbd{Configure} process, this will wipe out any
! 209: files from version 1.39.15 and below that might already be there. Libraries
! 210: and executable files from newer versions (starting with version 1.900) are
! 211: not removed since they are only links to files bearing the version number
! 212: (beware of that as well: if you're an avid GP fan, don't forget to delete the
! 213: old pari libraries once in a while).
! 214:
! 215: This installs in the directory chosen at \kbd{Configure} time the default GP
! 216: executable (probably \kbd{gp-dyn}) under the name \kbd{gp}, the default PARI
! 217: library (probably \kbd{libpari.so}), the necessary include files, the manual
! 218: pages, the documentation and help scripts and emacs macros.
! 219:
! 220: By default, if a dynamic library \kbd{libpari.so} could be built, the static
! 221: library \kbd{libpari.a} will not be created. If you want it as well, you can
! 222: use the target \kbd{make install-lib-sta}. You can install a statically
! 223: linked \kbd{gp} with the target \kbd{make install-bin-sta}. As a rule,
! 224: programs linked statically (with \kbd{libpari.a}) may be slightly faster
! 225: (about 5\% gain), but use much more disk space and take more time to compile.
! 226: They are also harder to upgrade: you will have to recompile them all instead
! 227: of just installing the new dynamic library. (On the other hand, there's no
! 228: risk of breaking them by installing a new pari library)
! 229:
! 230: \subsec{The Galois package:} The default \kbd{polgalois} function can only
! 231: compute Galois groups of polynomials of degree less or equal to 7. If you
! 232: want to handle polynomials of degree bigger than 7 (and less than 11), you
! 233: need to fetch a separate archive: \kbd{galdata.tgz} which can probably be
! 234: found at the same place where you got the main PARI archive, and on the
! 235: \kbd{megrez} ftp server in any case. Untar the archive in the \kbd{datadir}
! 236: directory which was chosen at \kbd{Configure} time (it's one of the last
! 237: messages on the screen if you did not run \kbd{Configure -a}). You can then
! 238: test the \kbd{polgalois} function with your favourite polynomials.
! 239:
! 240: \subsec{The \kbd{GPRC} file:} Copy \kbd{misc/gprc.dft} (or \kbd{gprc.dos} if
! 241: you're using \kbd{GP.EXE}) to \kbd{\$HOME/.gprc}. Modify it to your liking.
! 242: For instance, if you're not using an ANSI terminal, remove control characters
! 243: from the \kbd{prompt} variable. You can also enable colors.
! 244:
! 245: If desired, also copy/modify \kbd{misc/gpalias} somewhere and call it from
! 246: the \kbd{gprc} file (this provides some common shortcuts to lengthy names).
! 247: Finally, if you have superuser privileges and want to provide system-wide
! 248: defaults, you can copy your customized \kbd{.gprc} file to \kbd{/etc/gprc}.
! 249:
! 250: In older versions, \kbd{gphelp} was hidden in pari lib directory and wasn't
! 251: meant to be used from the shell prompt, but not anymore. If gp complains it
! 252: can't find \kbd{gphelp}, check whether your \kbd{.gprc} (or the system-wide
! 253: \kbd{gprc}) does contain explicit paths. If so, correct them according to the
! 254: current \kbd{misc/gprc.dft}.
! 255:
! 256: \section{Getting Started}
! 257:
! 258: \subsec{Printable Documentation:} To print the user's guide, for which you'll
! 259: need a working (plain) \TeX\ installation; type
! 260:
! 261: \kbd{make doc}
! 262:
! 263: \noindent This will create, in two passes, a file \kbd{doc/users.dvi}
! 264: containing the manual with a table of contents and an index. You must then
! 265: send the \kbd{users.dvi} file to your favourite printer in the usual way,
! 266: probably via \kbd{dvips}. Also included are a short tutorial
! 267: (\kbd{doc/tutorial.dvi}) and a reference card (\kbd{doc/refcard.dvi}
! 268: and \kbd{doc/refcard.ps}) for GP.
! 269:
! 270: \subsec{C programming:} Once all libraries and include files are installed,
! 271: you can link your C programs to the PARI library. A sample makefile
! 272: \kbd{examples/Makefile} is provided to illustrate the use of the various
! 273: libraries. Type \kbd{make all} in the \kbd{examples} directory to see how
! 274: they perform on the \kbd{mattrans.c} program, which is commented in the
! 275: manual.
! 276:
! 277: \subsec{GP scripts:} Several complete sample GP programs are also given in
! 278: the \kbd{examples} directory, for example Shanks's SQUFOF factoring method,
! 279: the Pollard rho factoring method, the Lucas-Lehmer primality test for
! 280: Mersenne numbers and a simple general class group and fundamental unit
! 281: algorithm (much worse than the built-in \kbd{bnfinit}!). See the file
! 282: \kbd{examples/EXPLAIN} for some explanations.
! 283:
! 284: \subsec{EMACS:} If you want to use \kbd{gp} under GNU Emacs, read the file
! 285: \kbd{emacs/pariemacs.txt}. If you are familiar with Emacs, we suggest that
! 286: you do~so.
! 287:
! 288: \subsec{The PARI Community:} There are three mailing lists devoted to the
! 289: PARI/GP package (run courtesy of Dan Bernstein), and most feedback should be
! 290: directed to those. They are:
! 291:
! 292: $\bullet$ \kbd{pari-announce}: to announce major version changes. You can't
! 293: write to this one, but you should probably subscribe.
! 294:
! 295: $\bullet$ \kbd{pari-dev}: for everything related to the development of PARI,
! 296: including suggestions, technical questions, bug reports or patch submissions.
! 297:
! 298: $\bullet$ \kbd{pari-users}: for everything else.
! 299:
! 300: To subscribe, send empty messages respectively to
! 301:
! 302: \centerline{\kbd{pari-announce-subscribe@list.cr.yp.to}}
! 303:
! 304: \centerline{\kbd{pari-users-subscribe@list.cr.yp.to}}
! 305:
! 306: \centerline{\kbd{pari-dev-subscribe@list.cr.yp.to}}
! 307:
! 308: If you are not a member of any of those lists and don't want to become one,
! 309: you can write to us at the address
! 310:
! 311: \centerline{\kbd{pari@math.u-bordeaux.fr}}
! 312:
! 313: At the very least, we will forward you mail to the lists above and correct
! 314: faulty behaviour, if necessary. But we cannot promise you will get an
! 315: individual answer.
! 316:
! 317: Last but not least, PARI home page (maintained by Gerhard Nicklasch) can be
! 318: found at
! 319:
! 320: \centerline{\wwwsite}
! 321:
! 322: In any case, if you like this software, we would appreciate if you could
! 323: send us an email message giving us some information about yourself and what
! 324: you use PARI for. Put as header of your message ``new user'', so we can
! 325: recognize it easily.
! 326: \medskip
! 327: {\bf Good luck and enjoy!}
