Libnfc
原文地址::http://nfc-tools.org/index.php?title=Libnfc
Public platform independent Near Field Communication (NFC) library
libnfc is the first libre low level NFC SDK and Programmers API released under the GNU Lesser General Public License.
It provides complete transparency and royalty-free use for everyone.
This list shows the current supported features.
All major operating systems are supported, including GNU/Linux, Mac OS X and Windows. Compilation should work out of the box on POSIX-systems.
This library supports various NFC hardware devices: dongles, flat and OEM devices.
The library currently supports modulations for ISO/IEC 14443 A and B, FeliCa, Jewel/Topaz tags and Data Exchange Protocol (P2P) as target and as initiator.
Download
Stable release
Stable releases can be found at libnfc download section.
Development version
Fetch current version using Git:
git clone https://github.com/nfc-tools/libnfc.git
Note: If you want all libnfc hardware drivers, you will need to have libusb (library and headers) plus on *BSD and GNU/Linux systems, libpcsclite (library and headers).
Under MacOSX, GNU/Linux, *BSD and probably a lot of POSIX systems you can compile development version using:
autoreconf -vis ./configure --enable-doc make sudo make install
If you want to (re)generate documentation:
make doc
Third party packages
- Debian packages by Nobuhiro Iwamatsu and Ludovic Rousseau
Installation
The following sections describe per platform how to install and use libnfc.
Because some dependencies (e.g. libusb and optionnal PCSC-Lite) are used, the requirements per platform can differ.
POSIX systems
Manual installation
First make sure you have required compilation dependencies, ie. you will need headers from:
- libusb
Download and extract libnfc archive
$ wget https://bintray.com/artifact/download/nfc-tools/sources/libnfc-x.x.x.tar.bz2 $ tar -xvzf libnfc-x.x.x.tar.gz
Configure and compile
$ cd libnfc-x.x.x $ ./configure --prefix=/usr --sysconfdir=/etc $ make
Please note that ./configure have an installation path prefix set as /usr/local and sysconfdir set as $PREFIX/etc as default. Use --prefix and sysconfdiroption, if you want another setup (see ./configure --help).
Make sure you have required run-time dependencies.
- libusb
Plug in NFC device, and test if libnfc detect it
$ libnfc/utils/nfc-scan-device -v
Place a tag on it and show it
$ libnfc/utils/nfc-list
Install libnfc into your system
$ sudo make install
Note: if you have any troubles, please read README and browse this wiki before asking (dumb) question on forum and/or maling-lists...
Debian / Ubuntu
First make sure you have required compilation dependencies.
$ sudo apt-get install libusb-dev
Download and extract libnfc archive
git clone https://github.com/nfc-tools/libnfc.git cd libnfc git checkout libnfc-1.7.1 git clean -d -f -x #rm ../libnfc*.deb git remote|grep -q anonscm||git remote add anonscm git://anonscm.debian.org/collab-maint/libnfc.git git fetch anonscm git checkout remotes/anonscm/master debian git reset dpkg-buildpackage -uc -us -b
Make sure you have required run-time dependencies.
$ sudo apt-get install libusb-0.1-4
Install libnfc into your system
$ sudo dpkg -i ../libnfc*.deb
Plug in NFC device, place a tag on it and test your installation
$ nfc-list
FreeBSD
Romain Tartière contributed a FreeBSD port of libnfc, thanks to him.
- To install the port:
cd /usr/ports/devel/libnfc/ && make install clean
- To add the package:
pkg_add -r libnfc
Gentoo
Thanks to Mike Auty, libnfc have a ebuild to be easily installed on Gentoo using usual way:
$ emerge libnfc
Fedora 12+
Thanks to François Kooman, libnfc library is now included in Fedora 12+ distribution.
Using command line interface
# yum install libnfc libnfc-devel libnfc-examples
- libnfc-devel contains development headers and libraries, its only necessary if you want to
compile your own applications requiring libnfc
- libnfc-examples contains the example tools like nfc-list.
Using graphical tools
- System -> Administration -> Add/Remove Software
- Search for libnfc and select the appropriate packages for installation.
Mac OS X
For installing dependencies, MacPorts download manager is used (available at: http://distfiles.macports.org/MacPorts/)
Install MacPorts following instructions from http://www.macports.org/install.php
Install pkg-config:
$ sudo port install pkgconfig
Install glib:
$ sudo port install glib
Install glib:
$ sudo port install libusb
Make sure it's the x86_64 version (when on the latest OS X):
$ lipo -info /usr/local/lib/libusb.dylib
As the libnfc's MacPort is not up-to-date, now follow Manual installation instructions to compile libnfc using usual autotools way.
Warning: We have previously posted a link to darwinports .com, according to MacPorts project: they are an impostor / phishing site designed to get donations from unsuspecting users. Donations made to that site do not benefit MacPorts project and the instructions shown there for installing software are incorrect.
