Thank you, we will investigate this issue

[liuq19]

The problem is the lack of avx instruction set, and it is used inbase64x.

@liuq19 Can this library only be used with cpu's that have the avx instruction set?

[liuq19]

The dependency is not necessary. We will fix it in the base64x library.

Thanks, I'd like to be notified when it's resolved.
