Installation Instructions
-*************************
+-------------------------

-
-Basic Installation
-==================
+In Brief
+~~~~~~~~
-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.
-
- 6. Often, you can also type `make uninstall' to remove the installed
- files again.
-
-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'.
+The following instructions apply to building libxs from an official release
+downloaded from the Crossroads I/O website. For building directly from Git,
+see below.
-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:
+On POSIX platforms, libxs uses the standard autotools build system. To
+build and install the library, ensure your system has a C++ compiler
+installed, and proceed with the following steps:
- CPU-COMPANY-SYSTEM
+1. Run `./configure`, then `make` to build the library.
+2. Optionally, run `make test` to run the built in test suite.
+3. Run `make install` as root.
+4. On Linux or other platforms which use ld.so for dynamic linking, run
+ `ldconfig` or equivalent as root to update your systems shared library
+ cache.
-where SYSTEM can have one of these forms:
+On Windows, solution files for Visual C++ 2010 are provided in the
+`builds/msvc/` subdirectory of the distribution.
- 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.
+Building from Git
+~~~~~~~~~~~~~~~~~
- 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 are building libxs directly from the Git tree, on POSIX platforms
+you will need to generate the `configure` script. This requires that you
+have `autoconf` and `automake` installed on your system. To generate
+`configure`, run `./autogen.sh`.
- 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'.
+Note that documentation in UNIX 'man' and HTML formats will only be built
+and installed from a Git tree if you have the `asciidoc` package installed
+on your system.
-Sharing Defaults
-================
+Once you have generated `configure` you can follow the brief steps above.
-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:
+Optional Features
+~~~~~~~~~~~~~~~~~
- CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+libxs provides several optional features or extensions. These are enabled
+using options to `configure`, or special project files for Windows.
-`configure' Invocation
-======================
+Common optional features, and their options to `configure`:
-`configure' recognizes the following options to control how it operates.
+ZeroMQ Compatibility::
+ Specify `--enable-libzmq` to enable building and installation of the
+ drop-in `libzmq` compatibility library for ZeroMQ applications. Note
+ that this will *overwrite* any existing installation of `libzmq` on your
+ system. For further details refer to `doc/xs_zmq.html` or 'xs_zmq(7)'.
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
+PGM multicast support::
+ Enabled with `--with-pgm` (using the copy of OpenPGM bundled with libxs)
+ or `--with-system-pgm` (using your system installation of OpenPGM).
+ Refer to `doc/xs_pgm.html` or 'xs_pgm(7)' for details on usage.
-`--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.
+Other Common Options
+~~~~~~~~~~~~~~~~~~~~
-`--config-cache'
-`-C'
- Alias for `--cache-file=config.cache'.
+Specifying the installation directory::
+ libxs is installed in `/usr/local` by default. To change this, specify
+ the `--prefix` option to `configure`.
-`--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).
+Selecting a poller implementation::
+ libxs will normally pick the correct poller to use on your platform. If
+ cross compiling, or building for an older system you may need to
+ override this using the `--with-poller` option.
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
+Disabling eventfd for older Linux::
+ If building libxs to run on an older Linux kernel you may need to
+ disable eventfd support. This can be done with the `--disable-eventfd`
+ option.
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.
+Disabling building and installing documentation::
+ Specifying `--without-documentation` disables any (re-)building or
+ installation of the AsciiDoc-generated documentation.
+Refer to `./configure --help` for a full list of supported options, and
+more information on settings affecting the build (e.g. cross compiling,
+choosing a particular compiler version, and so on).
