Hi there, It looks like you're trying to build Cap'n Proto 0.4, which was released in 2013. The latest version is 0.7, released in 2018 (I really need to do a new release...).
My best guess is that what you are seeing was a bug in the code which for some reason wasn't detected by compilers of the time, but once compilers did start detecting it, we probably fixed the bug. -Kenton On Fri, Apr 3, 2020 at 11:24 AM <842m...@gmail.com> wrote: > Hi. > > So I'm trying to build some project and capnproto is preventing me.
