Installation Instructions

2006 Free Software Foundation, Inc.
|
||||

This file is free documentation; the Free Software Foundation gives

unlimited permission to copy, distribute and modify it.
|
||||
|
||||
Basic Installation
|
||||
==================
|
||||
|
||||
Briefly, the shell commands `./configure; make; make install' should
|
||||
configure, build, and install this package. The following
|
||||
more-detailed instructions are generic; see the `README' file for
|
||||
instructions specific to this package.
|
||||
|
||||
The `configure' shell script attempts to guess correct values for
|
||||
various system-dependent variables used during compilation. It uses
|
||||
those values to create a `Makefile' in each directory of the package.
|
||||
It may also create one or more `.h' files containing system-dependent
|
||||
definitions. Finally, it creates a shell script `config.status' that
|
||||
you can run in the future to recreate the current configuration, and a
|
||||
file `config.log' containing compiler output (useful mainly for
|
||||
debugging `configure').
|
||||
|
||||
It can also use an optional file (typically called `config.cache'
|
||||
and enabled with `--cache-file=config.cache' or simply `-C') that saves
|
||||
the results of its tests to speed up reconfiguring. Caching is
|
||||
disabled by default to prevent problems with accidental use of stale
|
||||
cache files.
|
||||
|
||||
If you need to do unusual things to compile the package, please try
|
||||
to figure out how `configure' could check whether to do them, and mail
|
||||
diffs or instructions to the address given in the `README' so they can
|
||||
be considered for the next release. If you are using the cache, and at
|
||||
some point `config.cache' contains results you don't want to keep, you
|
||||
may remove or edit it.
|
||||
|
||||
The file `configure.ac' (or `configure.in') is used to create
|
||||
`configure' by a program called `autoconf'. You need `configure.ac' if
|
||||
you want to change it or regenerate `configure' using a newer version
|
||||
of `autoconf'.
|
||||
|
||||
The simplest way to compile this package is:
|
||||
|
||||
1. `cd' to the directory containing the package's source code and type
|
||||
`./configure' to configure the package for your system.
|
||||
|
||||
Running `configure' might take a while. While running, it prints
|
||||
some messages telling which features it is checking for.
|
||||
|
||||
2. Type `make' to compile the package.
|
||||
|
||||
3. Optionally, type `make check' to run any self-tests that come with
|
||||
the package.
|
||||
|
||||
4. Type `make install' to install the programs and any data files and
|
||||
documentation.
|
||||
|
||||
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'. There is
|
||||
also a `make maintainer-clean' target, but that is intended mainly
|
||||
for the package's developers. If you use it, you may have to get
|
||||
all sorts of other programs in order to regenerate files that came
|
||||
with the distribution.
|
||||
|
||||
Compilers and Options
|
||||
=====================
|
||||
|
||||
Some systems 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=c99 CFLAGS=-g LIBS=-lposix
|
||||
|
||||
*Note Defining Variables::, for more details.
|
||||
|
||||
Compiling For Multiple Architectures
|
||||
====================================
|
||||
|
||||
You can compile the package for more than one kind of computer at the
|
||||
same time, by placing the object files for each architecture in their
|
||||
own directory. To do this, you can use GNU `make'. `cd' to the
|
||||
directory where you want the object files and executables to go and run
|
||||
the `configure' script. `configure' automatically checks for the
|
||||
source code in the directory that `configure' is in and in `..'.
|
||||
|
||||
With a non-GNU `make', it is safer to compile the package for one
|
||||
architecture at a time in the source code directory. After you have
|
||||
installed the package for one architecture, use `make distclean' before
|
||||
reconfiguring for another architecture.
|
||||
|
||||
Installation Names
|
||||
==================
|
||||
|
||||
By default, `make install' installs the package's commands under
|
||||
`/usr/local/bin', include files under `/usr/local/include', etc. You
|
||||
can specify an installation prefix other than `/usr/local' by giving
|
||||
`configure' the option `--prefix=PREFIX'.
|
||||
|
||||
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.
|
||||
|
||||
If the package supports it, 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
|
||||
=================
|
||||
|
||||
Some packages pay attention to `--enable-FEATURE' options to
|
||||
`configure', where FEATURE indicates an optional part of the package.
|
||||
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
|
||||
is something like `gnu-as' or `x' (for the X Window System). The
|
||||
`README' should mention any `--enable-' and `--with-' options that the
|
||||
package recognizes.
|
||||
|
||||
For packages that use the X Window System, `configure' can usually
|
||||
find the X include and library files automatically, but if it doesn't,
|
||||
you can use the `configure' options `--x-includes=DIR' and
|
||||
`--x-libraries=DIR' to specify their locations.
|
||||
|
||||
Specifying the System Type
|
||||
==========================
|
||||
|
||||
There may be some features `configure' cannot figure out automatically,
|
||||
but needs to determine by the type of machine the package will run on.
|
||||
Usually, assuming the package is built to be run on the _same_
|
||||
architectures, `configure' can figure that out, but if it prints a
|
||||
message saying it cannot guess the machine type, give it the
|
||||
`--build=TYPE' option. TYPE can either be a short name for the system
|
||||
type, such as `sun4', or a canonical name which has the form:
|
||||
|
||||
CPU-COMPANY-SYSTEM
|
||||
|
||||
where SYSTEM can have one of these forms:
|
||||
|
||||
OS KERNEL-OS
|
||||
|
||||
See the file `config.sub' for the possible values of each field. If
|
||||
`config.sub' isn't included in this package, then this package doesn't
|
||||
need to know the machine type.
|
||||
|
||||
If you are _building_ compiler tools for cross-compiling, you should
|
||||
use the option `--target=TYPE' to select the type of system they will
|
||||
produce code for.
|
||||
|
||||
If you want to _use_ a cross compiler, that generates code for a
|
||||
platform different from the build platform, you should specify the
|
||||
"host" platform (i.e., that on which the generated programs will
|
||||
eventually be run) with `--host=TYPE'.
|
||||
|
||||
Sharing Defaults
|
||||
================
|
||||
|
||||
If you want to set default values for `configure' scripts to share, you
|
||||
can create a site shell script called `config.site' that gives default
|
||||
values for variables like `CC', `cache_file', and `prefix'.
|
||||
`configure' looks for `PREFIX/share/config.site' if it exists, then
|
||||
`PREFIX/etc/config.site' if it exists. Or, you can set the
|
||||
`CONFIG_SITE' environment variable to the location of the site script.
|
||||
A warning: not all `configure' scripts look for a site script.
|
||||
|
||||
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).
|
||||
|
||||
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
|
||||
an Autoconf bug. Until the bug is fixed you can use this workaround:
|
||||
|
||||
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
|
||||
|
||||
`configure' Invocation
|
||||
======================
|
||||
|
||||
`configure' 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.

# SYNOPSIS
|
||||
#
|
||||
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro figures out how to build C programs using POSIX threads. It
|
||||
# sets the PTHREAD_LIBS output variable to the threads library and linker
|
||||
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
|
||||
# flags that are needed. (The user can also force certain compiler
|
||||
# flags/libs to be tested by setting these environment variables.)
|
||||
#
|
||||
# Also sets PTHREAD_CC to any special C compiler that is needed for
|
||||
# multi-threaded programs (defaults to the value of CC otherwise). (This
|
||||
# is necessary on AIX to use the special cc_r compiler alias.)
|
||||
#
|
||||
# NOTE: You are assumed to not only compile your program with these flags,
|
||||
# but also link it with them as well. e.g. you should link with
|
||||
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
|
||||
#
|
||||
# If you are only building threads programs, you may wish to use these
|
||||
# variables in your default LIBS, CFLAGS, and CC:
|
||||
#
|
||||
# LIBS="$PTHREAD_LIBS $LIBS"
|
||||
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
||||
# CC="$PTHREAD_CC"
|
||||
#
|
||||
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
|
||||
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
|
||||
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
||||
#
|
||||
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
|
||||
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
|
||||
# is not found. If ACTION-IF-FOUND is not specified, the default action
|
||||
# will define HAVE_PTHREAD.
|
||||
#
|
||||
# Please let the authors know if this macro fails on any platform, or if
|
||||
# you have any other suggestions or comments. This macro was based on work
|
||||
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
|
||||
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
|
||||
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
|
||||
# grateful for the helpful feedback of numerous users.

# serial 4 lt~obsolete.m4
|
||||
|
||||
# These exist entirely to fool aclocal when bootstrapping libtool.
|
||||
#
|
||||
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
|
||||
# which have later been changed to m4_define as they aren't part of the
|
||||
# exported API, or moved to Autoconf or Automake where they belong.
|
||||
#
|
||||
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
|
||||
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
|
||||
# using a macro with the same name in our local m4/libtool.m4 it'll
|
||||
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
|
||||
# and doesn't know about Autoconf macros at all.)
|
||||
#
|
||||
# So we provide this file, which has a silly filename so it's always
|
||||
# included after everything else. This provides aclocal with the
|
||||
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
|
||||
# because those macros already exist, or will be overwritten later.
|
||||
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
|
||||
#
|
||||
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
|
||||
# Yes, that means every name once taken will need to remain here until
|
||||
# we give up compatibility with versions before 1.7, at which point
|
||||
# we need to keep only those names which we still refer to.
|
||||
|
||||
# This is to help aclocal find these macros, as it can't see m4_define.

// The ExceptionHandler object installs signal handlers for a number of
|
||||
// signals. We rely on the signal handler running on the thread which crashed
|
||||
// in order to identify it. This is true of the synchronous signals (SEGV etc),
|
||||
// but not true of ABRT. Thus, if you send ABRT to yourself in a program which
|
||||
// uses ExceptionHandler, you need to use tgkill to direct it to the current
|
||||
// thread.
|
||||
//
|
||||
// The signal flow looks like this:
|
||||
//
|
||||
// SignalHandler (uses a global stack of ExceptionHandler objects to find
|
||||
// | one to handle the signal. If the first rejects it, try
|
||||
// | the second etc...)
|
||||
// V
|
||||
// HandleSignal ----------------------------| (clones a new process which
|
||||
// | | shares an address space with
|
||||
// (wait for cloned | the crashed process. This
|
||||
// process) | allows us to ptrace the crashed
|
||||
// | | process)
|
||||
// V V
|
||||
// (set signal handler to ThreadEntry (static function to bounce
|
||||
// SIG_DFL and rethrow, | back into the object)
|
||||
// killing the crashed |
|
||||
// process) V
|
||||
// DoDump (writes minidump)
|
||||
// |
|
||||
// V
|
||||
// sys_exit
|
||||
//
|
||||
|
||||
// This code is a little fragmented. Different functions of the ExceptionHandler
|
||||
// class run in a number of different contexts. Some of them run in a normal
|
||||
// context and are easy to code, others run in a compromised context and the
|
||||
// restrictions at the top of minidump_writer.cc apply: no libc and use the
|
||||
// alternative malloc. Each function should have comment above it detailing the
|
||||
// context which it runs in.
