Hi Bram,

I'm seeing lots of warnings compiling on stock Ubuntu 19.10:

/usr/include/gtk-2.0/gtk/gtktooltips.h:73:3: warning: ‘GTimeVal’ is
deprecated: Use 'GDateTime' instead [-Wdeprecated-declarations]
73 | GTimeVal last_popdown;

This looks like https://github.com/vim/vim/issues/4987

Best,

Indeed (apologies, I totally forgot to search there too)

Although I'm unclear on the resolution - isn't a Vim fix required here?

I had the same issue after upgrading to 19.10.
The only solution I found so far is adding a flag to the compiler:
-Wno-deprecated-declarations

It looks like the gtk2 libraries declared something deprecated, so we
might need to adapt our code indeed. (apparently replacing GTimeVal by
GDateTime works according to the user opening this issue).

Thanks Bram - would it make sense to do something on the Vim side (assuming we can?) rather than relying on each Ubuntu 19.10 developer compiling Vim to tweak something?

I have no idea if changing this would break it on older systems.
Updating to a newer GTK version is no small thing, some users/systems
may not be willing/able to do that.

Perhaps the changes could be done with some #ifdef ?
We do that for GTK 3.
