-NOTICE:
-(2014-03-26)
-This is now the official Proxmark repository!
-
-INTRODUCTION:
-
-The proxmark3 is a powerful general purpose RFID tool, the size of a deck
-of cards, designed to snoop, listen and emulate everything from
-Low Frequency (125kHz) to High Frequency (13.56MHz) tags.
-
-This repository contains enough software, logic (for the FPGA), and design
-documentation for the hardware that you could, at least in theory,
-do something useful with a proxmark3.
-
-RESOURCES:

-DEVELOPMENT:
-
-The tools required to build or run the project will vary depending on
-your operating system. Please refer to the Wiki for details.
-
- * https://github.com/Proxmark/proxmark3/wiki
-
-OBTAINING HARDWARE:
-
-The Proxmark 3 is available for purcahse (assembled and tested) from the
-following locations:
-
- * http://proxmark3.com/
- * http://www.xfpga.com/
-
-Most of the ultra-low-volume contract assemblers could put
-something like this together with a reasonable yield. A run of around
-a dozen units is probably cost-effective. The BOM includes (possibly-
-outdated) component pricing, and everything is available from Digikey
-and the usual distributors.
-
-If you've never assembled a modern circuit board by hand, then this is
-not a good place to start. Some of the components (e.g. the crystals)
-must not be assembled with a soldering iron, and require hot air.
-
-The schematics are included; the component values given are not
-necessarily correct for all situations, but it should be possible to do
-nearly anything you would want with appropriate population options.
-
-The printed circuit board artwork is also available, as Gerbers and an
-Excellon drill file.

+Whats in this fork? I have scraped the web for different enhancements to the PM3 sourcecode and not all of them ever found their way to the master branch.
+Among the stuff is
+ * jonor's hf 14a raw timing patch
+ * Piwi's updates. (usually gets into the master)
+ * Holimans iclass, (usually gets into the master)
+ * Marshmellows LF fixes (will go into the master)
+ * Midnitesnakes Ultralight, Ultralight-c enhancements
+ * My desfire, Ultralight extras, LF T55xx enhancements, bugs fixes (filelength, hf mf commands ), TNP3xxx lua scripts, Awid26, skidata scripts (will come)
+ * other osbscury patches like for the sammy-mode, (offline you know), tagidentifications, defaultkeys.
+
+Give me a hint, and I'll see if I can't merge in the stuff you have.
+
+PM3 GUI:
+I do tend to rename and move stuff around, the official PM3-GUI from Gaucho will not work so good. *sorry*

+DEVELOPMENT:
-May 2007, Cambridge MA
+This fork is adjusted to compile on windows/mingw environment with Qt5.3.1 & GCC 4.8
+For people with linux you will need to patch some sourcecode and some small change to one makefile. If you are lazy, you google the forum and find asper's or holimans makefile or you find your solution below.
+
+Common errors linux/macOS finds
+Error:
+ * loclass/fileutils.c:15:2: warning: implicit declaration of function ‘_stat’ [-Wimplicit-function-declaration]
+Solution:
+ * Remove the "unscore" sign. In linux you use without underscore, in windows you need a underscore.
+
+Error:
+ * \client\makefile the parameter -lgdi32
+Solution:
+ * Remove parameter.
+
+Error:
+ * Using older Qt4.6 gives compilation errors.
+Solution
+ * Upgrade to Qt5.3.1
+ OR
+ * Change these two line in \client\makefile
+ CXXFLAGS = -I$(QTDIR)/include -I$(QTDIR)/include/QtCore -I$(QTDIR)/include/QtGui -I$(QTDIR)/include/QtWidgets -I/mingw/include
+ QTLDLIBS = -L$(QTDIR)/lib -lQt5Core -lQt5Gui -lQt5Widgets

+ TO
+
+ CXXFLAGS = -I$(QTDIR)/include -I$(QTDIR)/include/QtCore -I$(QTDIR)/include/QtGui
+ QTLDLIBS = -L$(QTDIR)/lib -lQtCore4 -lQtGui4
+
+
+And old Qt4 version is found here: http://www.icesql.se/proxmark3/code/linuxmakefile.txt but this one doesn't have all new files in it. So I don't recommend it.
