Installation Instructions for Windows
*************************************
If you are compiling for MinGW or cygwin, please refer to the INSTALL file.
If you are using Microsoft Visual Studio:
- Open the relevant solution file in /msvc:
libusb.dsw for MSVC6, libusb_2005.sln for Visual Studio 2005 or 2008,
libusb_2010.sln for Visual Studio 2010,
libusb_2012.sln for Visual Studio 2012 or later,
libusb_wince.sln for Windows CE support in Visual Studio 2005.
- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define
in msvc\config.h
- Select your configuration and compile the project
Note that if you are using Visual Studio Express, you may have to install the
Windows SDK to be able to compile the 64 bit version of the library.
If you are using the freely available Windows DDK/WDK (Driver Development Kit)
- If you want to debug the library, uncomment the ENABLE_DEBUG_LOGGING define
in msvc\config.h
- Open one of the relevant Free Build or Checked Build prompt for your target
platform
- Navigate to the msvc\ directory where the ddk_build.cmd file is located, and
run 'ddk_build'
- To produce a DLL rather than a static library, use: 'ddk_build DLL'
- To produce a static library that uses LIBCMT[d] instead of MSVCRT[d] (/MT[d]
vs /MD[d] in Visual Studio) use: 'ddk_build /MT'
Note that using the Windows DDK, it is possible to compile both the 32 and 64
bit versions of the library.
If you are building for Windows CE then you will need the Windows CE Standard 5.00 SDK.
Destination directories
***********************
The 32 bit binaries compiled either from Visual Studio or the DDK are placed in
a Win32\ directory at the root of the library
The 64 bit binaries are placed in an x64\ directory
Windows CE binaries are placed in one of the following directories, depending
on the target processor: ARMV4I, MIPSII, MIPSII_FP, MIPSIV, MIPSIV_FP, SH4 or x86.
Troubleshooting
***************
If the compilation process complains about missing libraries, ensure that the
default library paths for your project points to the relevant directories.
If needed, these libraries can be obtained by installing either the latest
Windows SDK or the DDK (Links provided at the end of this file).
For Windows CE it is necessary to install the CE USB Kernel Wrapper driver for
libusb to function on a device.

[![Coverity Scan Build Status](https://scan.coverity.com/projects/2180/badge.svg)](https://scan.coverity.com/projects/libusb-libusb)
libusb is a library for USB device access from Linux, Mac OS X,
Windows, OpenBSD/NetBSD and Haiku userspace.
It is written in C (Haiku backend in C++) and licensed under the GNU
Lesser General Public License version 2.1 or, at your option, any later
version (see [COPYING](COPYING)).
libusb is abstracted internally in such a way that it can hopefully
be ported to other operating systems. Please see the [PORTING](PORTING)
file for more information.

Notes related to git compilation:
--------------------------------
If you retrieved the libusb repository from git and are using a gcc based
toolchain, be mindful that you should have the autotools installed (autoconf,
automake) and will need to run either ./autogen.sh or ./bootstrap.sh to produce
the configure file.
The difference between autogen.sh and bootstrap.sh is that the former invokes
configure with a default set of options, and will therefore generate a Makefile,
whereas the latter does not invoke configure at all. If using autogen.sh, note
that you can also append options, that will be passed as is to configure.
OS X-specific notes:
-------------------
Starting with Xcode 4.3, neither Xcode.app nor the Xcode 'command line tools'
includes autotools and so running either autogen.sh or bootstrap.sh will result
in the message:
libtoolize or glibtoolize was not found! Please install libtool.
To proceed, you must find and install it from somewhere.
Alternatively, you can use the Xcode project at Xcode/libusb.xcodeproj.
Notes related to submitting new developments:
--------------------------------------------
If you submit a new development to libusb (eg: new backend), that is unlikely
to fit in a couple of small patches, we would kindly suggest that you create a
public account on github, if you don't have one already, and then fork a new
libusb repository under this account from https://github.com/libusb/libusb.
Then you can create a git branch for your work, that we will be able to better
reference and test.
We also suggest that, if you are planning to bring in a large development, you
try to involve the libusb community early by letting the mailing list know, as
you may find that other people might be eager to help you out.
See http://mailing-list.libusb.info for details on how to join the mailing list.
