ZXing C++ Port

ZXing is/was a Java library.

At some point a complete C++ port/rewrite was created and maintained in the official ZXing repo. However, at the time of writing the C++ port is no longer maintained and has been removed from the official ZXing repo.

This project was forked from the zxing-cpp to contain the C++ project, with try to keep zxing-cpp up-to-date with zxing-java version. Current progress:

1. Migrated PDF417
2. Migrated DataMatrix ... To be continue

Building using CMake

CMake is a tool, that generates native makefiles and workspaces. It integrates well with a number of IDEs including Qt Creator and Visual Studio.

Usage with CLion or Qt Creator:

1. Simply open CMakeLists.txt as a new project
2. Additional command line arguments can be specified (see below)

Usage with Makefiles, Visual Studio, etc. (see cmake --help for a complete list of generators):

1. mkdir build
2. cd to build
3. Unix: run cmake -G "Unix Makefiles" ..
4. Windows: run cmake -G "Visual Studio 10" ..

You can switch between build modes by specifying:

• -DCMAKE_BUILD_TYPE=Debug or
• -DCMAKE_BUILD_TYPE=Release

Development tips

To profile the code (very useful to optimize the code):

1. Install Valgrind
2. Run valgrind --tool=callgrind build/zxing - path/to/test/data/*.jpg > report.html
3. Analyze output using KCachegrind
