# ZXing C++ Port
[ZXing](https://github.com/zxing/zxing) is/was a Java library.
At some point a complete C++ port/rewrite was created and maintained in the official [ZXing](https://github.com/zxing/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 However, at the time of writing the C++ port is no longer maintained and has been removed from the official ZXing repo.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](https://github.com/zxing/zxing/commit/00f6340) 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:
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" ..`
3. 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

zwl6136136132016-09-08下载后打开工程，却没有一个源码，可能我不会用吧，希望会用的可以指教一下
延陵小明2016-05-21确实可以用
李启昂dl2017-09-25执行报错 不会用
