The remaining sections describe how to configure the system such that
you can build the in-tree documentation.
Installing OpenOCD
==================
+On Linux, you may have permissions problems to address. The best
+way to do this is to use the contrib/udev.rules file. It probably
+belongs somewhere in /etc/udev/rules.d, but consult your operating
+system documentation to be sure. In particular, make sure that it
+matches the syntax used by your operating system's version of udev.

A Note to OpenOCD Users
-----------------------
The INSTALL file contains generic instructions for running 'configure'
and compiling the OpenOCD source code. That file is provided by default
-for all GNU automake packages, and
+for all GNU automake packages. If you are not familiar with the GNU
+autotools, then you should read those instructions first.

OpenOCD Dependencies
--------------------
-You will need to install the appropriate driver files, if you want to
+Presently, GCC is required to build OpenOCD. The developers have begun
+to enforce strict code warnings (-Wall, -Werror, -Wextra, and more) and
+use C99-specific features: inline functions, named initializers, mixing
+declarations with code, and other tricks. While it may be possible to
+use other compilers, they must be somewhat modern and could require
+extending support to conditionally remove GCC-specific extensions.
+
+Also, you need to install the appropriate driver files, if you want to
build support for a USB or FTDI-based interface:
- ft2232, jlink, rlink, vsllink, usbprog, arm-jtag-ew:
- ft2232 also requires:
- libftdi: http://www.intra2net.com/opensource/ftdi/ *OR*
- ftd2xx: http://www.ftdichip.com/Drivers/D2XX.htm,
- or the Amontec version (from @uref{http://www.amontec.com}), for
+ or the Amontec version (from http://www.amontec.com), for
easier support of JTAGkey's vendor and product IDs.
+Many Linux distributions provide these packages through their automated
+installation and update mechanisms; however, some Linux versions include
+older versions of libftdi. In particular, using Ubuntu 8.04 has been
+problematic, but newer versions of Ubuntu do not have this problem.
+
Compiling OpenOCD
-----------------
final (optional) step, ``make install'', places all of the files in the
required location.
+Cross-Compiling Options
+-----------------------
+
+To cross-compile, you must specify both --build and --host options to
+the 'configure' script. For example, you can configure OpenOCD to
+cross-compile on a x86 Linux host to run on Windows (MinGW32), you could
+use the following configuration options:
+
+ ./configure --build=i686-pc-linux-gnu --host=i586-mingw32msvc ...
+
+Likewise, the following options allow OpenOCD to be cross-compiled for
+an ARM target on the same x86 host:
+
+ ./configure --build=i686-pc-linux-gnu --host=arm-elf ...
+
+Both must be specified to work around bugs in autoconf.
+
+Scripts for producing ARM cross-compilers can be found on the web with a
+little searching. A script to produce an x86 Linux-hosted MinGW32
+cross-compiler can be downloaded from the following URL:
+
+ http://www.mingw.org/wiki/LinuxCrossMinGW
+
Configuration Options
---------------------
--disable-wextra Disable extra compiler warnings
--disable-werror Do not treat warnings as errors
- --enable-release Enable building of an OpenOCD release. This
- option is intended for project maintainers.
- It simply omits the svn version string when
- the openocd -v is executed (to KISS).
-
--disable-option-checking
Ignore unrecognized --enable and --with options.
--disable-dependency-tracking speeds up one-time build
Using LIBFTDI
-------------
+The libftdi source code can be download from the following website:
+
+ http://www.intra2net.com/en/developer/libftdi/download.php
+
For both Linux and Windows, both libusb and libftdi must be built and
installed. To use the newer FT2232H chips, supporting RTCK and USB high
speed (480 Mbps), you need libftdi version 0.16 or newer. Many Linux
Using FTDI's FTD2XX
-------------------
-Some claim the (closed) FTDICHIP.COM solution is faster, which
+The (closed source) FTDICHIP.COM solution is faster on MS-Windows. That
is the motivation for supporting it even though its licensing restricts
it to non-redistributable OpenOCD binaries, and it is not available for
all operating systems used with OpenOCD. You may, however, build such
_distributing_ copies of OpenOCD built with the FTDI code would violate
the OpenOCD licensing terms.

-Cygwin/Win32 Notes
-******************
-
-The Cygwin/Win32 ZIP file contains a directory named ftd2xx.win32.
-Assuming that you have extracted this archive in the same directory as
-the OpenOCD package, you could configure with options like the following:
-
- ./configure \
- --enable-ft2232_ftd2xx \
- --with-ftd2xx-win32-zipdir=../ftd2xx.win32 \
- ... other options ...
-
Linux Notes
***********
--with-ft2xx-linux-tardir=../libftd2xx0.4.16 \
... other options ...
+Note that on Linux there is no good reason to use these FTDI binaries;
+they are no faster (on Linux) than libftdi, and cause licensing issues.

Obtaining OpenOCD From Subversion
---------------------------------
svn checkout svn://svn.berlios.de/openocd/trunk openocd
-If you prefer GIT based tools, the @command{git-svn} package works too:

************************************************
Building OpenOCD from a repository requires a recent version of the GNU

-Windows, you have to use Cygwin. Make sure that your @env{PATH}
-environment variable contains no other locations with Unix utils (like
-UnxUtils) - these can't handle the Cygwin paths, resulting in obscure
-dependency errors. This was an observation gathered from the logs of

+autotools (autoconf >= 2.59 and automake >= 1.9).
1) Run './bootstrap' to create the 'configure' script and prepare
the build process for your host system.
2) Run './configure --enable-maintainer-mode' with other options.
