Compilation issue: narrowing #304

Closed ycnakajsph closed 5 months ago

ycnakajsph commented 5 months ago

Hi there,

I'm trying to build this library using Yocto (a tool to build distributions and packages for embedded Linux). I'm having some not so strict compilation flags however I'm having some problems with narrowing, I've been able to bypass that error using -Wno-narrowing but the issue still exists.

This was fix after the 2.2.0 release.

It's time to do a new release....
