Installation

For *NIX systems

You can use released version (see Download section) or development version:

First, ensure all dependencies are installed:

  • libnfc;
  • git;
  • Autotools (autoconf, automake, libtool);
  • OpenSSL development package.
apt-get install autoconf automake git libtool libssl-dev pkg-config

Clone this repository:

git clone https://github.com/nfc-tools/libfreefare.git
cd libfreefare

Before compiling, remember to run:

autoreconf -vis

You can now compile libfreefare the usual autotools way:

./configure --prefix=/usr
make
sudo make install

For Windows Systems

Requirements

  • cmake
  • make
  • mingw{32,64}-gcc

Building

mingw64-cmake -DLIBNFC_INCLUDE_DIRS=/path/to/libnfc-source/include  -DLIBNFC_LIBRARIES=/path/to/libnfc.dll
mingw64-make

Debug

In order to debug using gdb, you should tune the CFLAGS:

CFLAGS="-O0 -ggdb" ./configure --prefix=/usr
make clean all

It is then possible to debug examples using this kind of command from the root of the repository:

./libtool --mode=execute gdb examples/mifare-classic-write-ndef

If you are only interested in viewing transfert traces between the PCD and the PICC, simply use the --enable-debug configure flag:

./configure --enable-debug
make clean all
