Installation Instructions

|

|
||||
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. Some packages provide this
|
||||
`INSTALL' file but do not implement all of the features documented
|
||||
below. The lack of an optional feature in a given package is not
|
||||
necessarily a bug. More recommendations for GNU packages can be found
|
||||
in *note Makefile Conventions: (standards)Makefile Conventions.
|
||||
|
||||
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, generally using the just-built uninstalled binaries.
|
||||
|
||||
4. Type `make install' to install the programs and any data files and
|
||||
documentation. When installing into a prefix owned by root, it is
|
||||
recommended that the package be configured and built as a regular
|
||||
user, and only the `make install' phase executed with root
|
||||
privileges.
|
||||
|
||||
5. Optionally, type `make installcheck' to repeat any self-tests, but
|
||||
this time using the binaries in their final installed location.
|
||||
This target does not install anything. Running this target as a
|
||||
regular user, particularly if the prior `make install' required
|
||||
root privileges, verifies that the installation completed
|
||||
correctly.
|
||||
|
||||
6. 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.
|
||||
|
||||
7. Often, you can also type `make uninstall' to remove the installed
|
||||
files again. In practice, not all packages have tested that
|
||||
uninstallation works correctly, even though it is required by the
|
||||
GNU Coding Standards.
|
||||
|
||||
8. Some packages, particularly those that use Automake, provide `make
|
||||
distcheck', which can by used by developers to test that all other
|
||||
targets like `make install' and `make uninstall' work correctly.
|
||||
This target is generally not run by end users.
|
||||
|
||||
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 `..'. This
|
||||
is known as a "VPATH" build.
|
||||
|
||||
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.
|
||||
|
||||
On MacOS X 10.5 and later systems, you can create libraries and
|
||||
executables that work on multiple system types--known as "fat" or
|
||||
"universal" binaries--by specifying multiple `-arch' options to the
|
||||
compiler but only a single `-arch' option to the preprocessor. Like
|
||||
this:
|
||||
|
||||
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
||||
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
||||
CPP="gcc -E" CXXCPP="g++ -E"
|
||||
|
||||
This is not guaranteed to produce working output in all cases, you
|
||||
may have to build one architecture at a time and combine the results
|
||||
using the `lipo' tool if you have problems.
|
||||
|
||||
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', where PREFIX must be an
|
||||
absolute file name.
|
||||
|
||||
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. In general, the
|
||||
default for these options is expressed in terms of `${prefix}', so that
|
||||
specifying just `--prefix' will affect all of the other directory
|
||||
specifications that were not explicitly provided.
|
||||
|
||||
The most portable way to affect installation locations is to pass the
|
||||
correct locations to `configure'; however, many packages provide one or
|
||||
both of the following shortcuts of passing variable assignments to the
|
||||
`make install' command line to change installation locations without
|
||||
having to reconfigure or recompile.
|
||||
|
||||
The first method involves providing an override variable for each
|
||||
affected directory. For example, `make install
|
||||
prefix=/alternate/directory' will choose an alternate location for all
|
||||
directory configuration variables that were expressed in terms of
|
||||
`${prefix}'. Any directories that were specified during `configure',
|
||||
but not in terms of `${prefix}', must each be overridden at install
|
||||
time for the entire installation to be relocated. The approach of
|
||||
makefile variable overrides for each directory variable is required by
|
||||
the GNU Coding Standards, and ideally causes no recompilation.
|
||||
However, some platforms have known limitations with the semantics of
|
||||
shared libraries that end up requiring recompilation when using this
|
||||
method, particularly noticeable in packages that use GNU Libtool.
|
||||
|
||||
The second method involves providing the `DESTDIR' variable. For
|
||||
example, `make install DESTDIR=/alternate/directory' will prepend
|
||||
`/alternate/directory' before all installation names. The approach of
|
||||
`DESTDIR' overrides is not required by the GNU Coding Standards, and
|
||||
does not work on platforms that have drive letters. On the other hand,
|
||||
it does better at avoiding recompilation issues, and works well even
|
||||
when some directory options were not specified in terms of `${prefix}'
|
||||
at `configure' time.
|
||||
|
||||
Optional Features
|
||||
=================
|
||||
|
||||
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'.
|
||||
|
||||
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.
|
||||
|
||||
Some packages offer the ability to configure how verbose the
|
||||
execution of `make' will be. For these packages, running `./configure
|
||||
--enable-silent-rules' sets the default to minimal output, which can be
|
||||
overridden with `make V=1'; while running `./configure
|
||||
--disable-silent-rules' sets the default to verbose, which can be
|
||||
overridden with `make V=0'.
|
||||
|
||||
Particular systems
|
||||
==================
|
||||
|
||||
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
|
||||
CC is not installed, it is recommended to use the following options in
|
||||
order to use an ANSI C compiler:
|
||||
|
||||
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
|
||||
|
||||
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
|
||||
|
||||
HP-UX `make' updates targets which have the same time stamps as
|
||||
their prerequisites, which makes it generally unusable when shipped
|
||||
generated files such as `configure' are involved. Use GNU `make'
|
||||
instead.
|
||||
|
||||
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
|
||||
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
|
||||
a workaround. If GNU CC is not installed, it is therefore recommended
|
||||
to try
|
||||
|
||||
./configure CC="cc"
|
||||
|
||||
and if that doesn't work, try
|
||||
|
||||
./configure CC="cc -nodtk"
|
||||
|
||||
On Solaris, don't put `/usr/ucb' early in your `PATH'. This
|
||||
directory contains several dysfunctional programs; working variants of
|
||||
these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
|
||||
in your `PATH', put it _after_ `/usr/bin'.
|
||||
|
||||
On Haiku, software installed for all users goes in `/boot/common',
|
||||
not `/usr/local'. It is recommended to use the following options:
|
||||
|
||||
./configure --prefix=/boot/common
|
||||
|
||||
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 limitation. Until the limitation is lifted, you can use
|
||||
this workaround:
|
||||
|
||||
CONFIG_SHELL=/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 all of the options to `configure', and exit.
|
||||
|
||||
`--help=short'
|
||||
`--help=recursive'
|
||||
Print a summary of the options unique to this package's
|
||||
`configure', and exit. The `short' variant lists options used
|
||||
only in the top level, while the `recursive' variant lists options
|
||||
also present in any nested packages.
|
||||
|
||||
`--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.
|
||||
|
||||
`--prefix=DIR'
|
||||
Use DIR as the installation prefix. *note Installation Names::
|
||||
for more details, including other options available for fine-tuning
|
||||
the installation locations.
|
||||
|
||||
`--no-create'
|
||||
`-n'
|
||||
Run the configure checks, but stop before creating any output
|
||||
files.
|
||||
|
||||
`configure' also accepts some other, not widely useful, options. Run
|
||||
`configure --help' for more details.

Breakpad is a set of client and server components which implement a
|
||||
crash-reporting system.
|
||||
|
||||
|
||||
-----
|
||||
Getting started in 32-bit mode (from trunk)
|
||||
Configure: CXXFLAGS=-m32 CFLAGS=-m32 CPPFLAGS=-m32 ./configure
|
||||
Build: make
|
||||
Test: make check
|
||||
Install: make install
|
||||
|
||||
If you need to reconfigure your build be sure to run "make distclean" first.
|
||||
|
||||
|
||||
-----
|
||||
To request change review:
|
||||
0. Get access to a read-write copy of source.
|
||||
Owners at http://code.google.com/p/google-breakpad/ are able to grant
|
||||
this access.
|
||||
|
||||
1. Check out a read-write copy of source using instructions at
|
||||
http://code.google.com/p/google-breakpad/source/checkout
|
||||
|
||||
2. Make changes. Build and test your changes.
|
||||
For core code like processor use methods above.
|
||||
For linux/mac/windows, there are test targets in each project file.
|
||||
|
||||
3. Download http://codereview.appspot.com/static/upload.py
|
||||
|
||||
4. Run upload.py from the 'src' directory:
|
||||
upload.py --server=breakpad.appspot.com
|
||||
|
||||
You will be prompted for credential and a description.
|
||||
|
||||
5. At http://breakpad.appspot.com you'll find your issue listed; click on it,
|
||||
and select Publish+Mail, and enter in the code reviewer and CC
|
||||
google-breakpad-dev@googlegroups.com
|
||||
|
||||
6. When applying code review feedback, specify the '-i' option when running
|
||||
upload.py again and pass the issue number so it updates the existing issue,
|
||||
rather than creating a new one.
|
||||
Be sure to rerun upload.py from the same directory as you did for previous
|
||||
uploads to allow for proper diff calculations.

## -MM, not -M (despite what the docs say). Also, it might not be
|
||||
## supported by the other compilers which use the 'gcc' depmode.

## This next piece of magic avoids the "deleted header file" problem.

## The problem is that when a header file which appears in a .P file

## is deleted, the dependency causes make to die (because there is
|

## typically no way to rebuild the header). We avoid this by adding
|
||||
## dummy dependencies for each header file. Too bad gcc doesn't do
|
||||
## this for us directly.
|

## Some versions of gcc put a space before the ':'. On the theory
|
||||
## that the space means something, we add a space to the output as
|
||||
## well. hp depmode also adds that space, but also prefixes the VPATH
|

## to the object. Take care to not repeat it in the output.

# 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.

# 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

# 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.
