SebGDev 975b67b248 Bugfix UPCAReader: The maybeReturnResult function checks whether the Result

is UPCA or EAN13. The old version returned an uninitialised Ref<Result>
(at the EAN13 case) which let MultiFormatUPCEANReader::decodeRow (line 90)
crash because a Result is assumed.

The bugfix is technically oriented at the java version.

Note: This error doesn't appear at normal tests because the MultiFormatUPCEANReader
uses the EAN13 reader for UPC-A detection. The UPCAReader is only used if
DecodeHints BarcodeFormat::UPC_A ist set.

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 However, at the time of writing the C++ port is no longer maintained and has been removed from the official ZXing repo.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 last ZXing commit to contain the C++ project, with the following exceptions

scons (Python) build system has been deleted.
Deleted black box tests, because they refer to a large test data in ZXing repo.
Added appropriate copyright/licensing details (based on those in the ZXing repo).
Updated README.md

Removal of build systems was done to minimise maintenance burden.

If tests and XCode projects (other than those produced automatically be CMake) are desired, then another repo should be created and this repo referenced as a submodule.

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:

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

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

cd to cpp/build
Unix: run cmake -G "Unix Makefiles" ..
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):

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

To run the black box tests and check for changes:

Build zxing-img, e.g., scons zxing
Run the tests: bash blackboxtest.sh 2>&1 | tee bb.results
Diff them with the known results: diff bb.results blackboxtest.results
