如何自行编译

[YXH-YXH]

我执行了根目录下的easy_dist.bat脚本，出现如下报错

想确认一下，是不是我使用的msys64不支持编译此项目，正常编译应该使用那个版本的编译器？

[WHYBBE]

如果不在乎编译大小，直接去掉-m32就行了
gcc main.c qrcodegen.c codec.c -o qrcode.exe -s -static -mwindows
剪裁一下upx -9 qrcode.exe也就41KB

[znsoooo]

我用的是mingw-8.1.0编译，可以在这里下载：https://sourceforge.net/projects/mingw-w64/files/mingw-w64/mingw-w64-release
我选择的是x86_64-posix-sjlj，但是其他有几个也是可以编译的，你可以都试试。
另外楼上说的编译参数-m32 -s -static和upx，都是可以去掉的，影响的是文件体积和跨平台能力，但是可以编译并运行。

另外，这里提供了编译之后的版本，支持32/64位系统，支持Windows XP，如有需要可以直接下载：

最近更新修复了能直接读取UTF-16格式的文件。
