https://github.com/nayuki/QR-Code-generator 编译和引用很成功,但目前只能输出 svg 的字符串,或者字符表示,需要结合Libpng 进行作图。

工具命令行:
F:\YZBX\CPP\CLR001\CLR001_empty\gnu\libqrencode-master\build\Release>qrencode.ex e -o hello.png -v 1 helloworld -v 选择1,2,3 都比较容易识别。

I made some recent improvements to my library. I believe I have fixed this compile-time error. Please feel free to try the new code now.
