---------------------

Exiv2 works well with Qt.

Qt requires C++11 libraries which are the default for Exiv2 v0.28 and later.
Exiv2 v0.27 default build (and pre-built binaries) are for C++98
You will have to build Exiv2 v0.27 from source with C++11 for Qt.

To build and run commandLineTool
--------------------------------

1) Windows Users should install MinGW/msys2 as documented in README.md

2) All users should build Exiv2 with C++11 support as documented in README.md

3) Generate Makefile
   Caution: You will have to modify commandLineTool.pro to fit your environment.
   $ cd <exiv2dir>
   $ cd contrib/Qt
   $ qmake commandLinePro.pro

4) Build commandLineTool.cpp
   $ make

5) Run commandLineTool.exe
   $ commandLineTool.exe

UNICODE_PATH on Windows
-----------------------

Windows users may prefer to build Exiv2 to support UNICODE_PATH.
The sample application samples/exifprint.cpp works with UNICODE_PATH.
The cmake option -DEXIV2_ENABLE_WIN_UNICODE=ON is documented in README.md
