If I use e.g. "meson build && ninja -C build && ninja -C build install" here I get a copy that does have the right version in it. I haven't looked too closely at how it does that though. Since it appears to work equally well with %VERSION% in the .in file, and it's obviously not great to have a wrong literal value in there, I'll make that change. That page just makes my head spin a little faster if anything! It seems rather libtool-specific and doesn't indicate how current:revision:age maps on to the installed library suffix. Is "current" the soname number, "revision" the minor number, and "age" the point number, as I would naively read it? If so, then it appears to be saying that merely adding a function *should* result in incrementing the soname: "If any interfaces have been added, removed, or changed since the last update, increment current, and set revision to 0" where "current" is the soname, right? As I read it, it seems to be saying that if the current version is (say) 2.1.7, then a backward-compatible addition should result in an updated version 3.0.8 whereas an incompatible change should result in 3.0.0. I'm not sure I understand the logic regardless of the explanation in the page. I don't recall having ever read quite that method before. Chris
