Package does not build

[koheiw]

Hi @gagolews,

I was so happy to find that stringi functions are exposed to C++, and jumped onto this package to learn how to use it in our quanteda package, but I am facing an error like this when I build the package (or source test.cpp). Can you give me advice on how to avoid this?

Thank you for making the amazing package.

Took long, but a fix is there.

Fantastic! Thank you @gagolews.
