Unfortunately, the most used library libdecodeqris depends on OpenCV (gtk2) and it is too hard to compile it on OS X. (Tried to compile it because it is needed by Image::DecodeQRperl module - but unsuccessful).
不幸的是，最常用的库libdecodeqr依赖于 OpenCV (gtk2)，并且在 OS X 上编译它太难了。（尝试编译它，因为Image::DecodeQRperl 模块需要它- 但没有成功）。
Fortunately, found this link: http://macscripter.net/viewtopic.php?id=37404from citing the next:
幸运的是，找到了这个链接：http: //macscripter.net/viewtopic.php?id = 37404从引用下：
- Download the ZBar source code.
- Unpack the the tarball, and open the resulting directory in a Terminal window.
- Type
./configure --disable-video --without-python --without-gtk --without-qtto configure the build process, limiting dependencies to ImageMagick. - Type "make" to invoke the build process.
- Type "sudo make install", and enter an administrator password when prompted.
- 下载ZBar 源代码。
- 解压缩 tarball，并在终端窗口中打开生成的目录。
- 键入
./configure --disable-video --without-python --without-gtk --without-qt以配置构建过程，限制对 ImageMagick 的依赖。 - 键入“make”以调用构建过程。
- 键入“sudo make install”，并在出现提示时输入管理员密码。
You will need ImageMagickwhat can be installed from macports.
您将需要ImageMagick可以从macports安装的内容。
After installing the ZBar, you can nicely decode qrcode with a command
安装 ZBar 后，您可以使用命令很好地解码 qrcode
zbarimg qrcode_file.png
Tested on OS X Mavericks 10.9.2 (and Lion/10.7.5)- and works nicely. Becasue it only depends on ImageMagick (exists in macports)- should be easily "compilable" on other OS X versions too.
在 OS X Mavericks 10.9.2（和 Lion/10.7.5）上测试过，效果很好。因为它只依赖于 ImageMagick（存在于 macports 中） - 也应该很容易在其他 OS X 版本上“编译”。

Using brew, it is easy to install zbar, a QR code reader.
使用 brew，很容易安装 zbar，一个二维码阅读器。
brew install zbar
Then a QR code can be read by calling:
然后可以通过调用读取二维码：
zbarimg qrcode_file.png
Also @jm666, brew can be used to install opencv.
另外@jm666，brew 可用于安装 opencv。

I managed to compile qrencode 2.0 a few months ago on my iMac. You need the developer tools installed (obviously), I can't remember if I need to build any additional libraries first like libpng or something like that. But that's for encoding strings as QR images...
几个月前，我设法在 iMac 上编译了 qrencode 2.0。您需要安装开发人员工具（显然），我不记得是否需要先构建任何其他库，例如 libpng 或类似的东西。但那是为了将字符串编码为 QR 图像......
You can use the Java QR Code Libraryon SourceForge, I also tried it on a Mac to decode images that I encoded with qrencode 2.0 and it worked fine.
您可以在 SourceForge 上使用Java QR 代码库，我也在 Mac 上尝试使用它来解码我使用 qrencode 2.0 编码的图像，并且效果很好。

Here's one that uses your webcam and works in realtime like a QR decoder for a phone. It's based on AdobeAir and works reasonably well.
这是一个使用您的网络摄像头并像手机的二维码解码器一样实时工作的产品。它基于 AdobeAir，运行良好。
