Compile using –with-gtk=3

[Marco Trevisan (Treviño)]

wxwidgets support gtk3 backend since some versions.

Using gtk3 as backend would also allow to get native support in other display servers such as mir and wayland.

FYI, wxwidgets 3 built --with-gtk=3 is problematic for KiCad.

I talked to wx upstream when packaging wx3.0 for Debian, and their recommendation at that point was firmly to stick with gtk2 for now.

That would have been around October 2013, so ~18 months ago as I write. Checking "git log -i --grep=gtk3" shows 19 GTK3 related commits on the 3.0 branch since then, so things may have evolved, but it sounds from what nickoe says that it's not as solid as the gtk2 support yet.

Switching gtk version is going to need significant amounts of testing of reverse dependencies, and quite likely a rebuild of all the C++ ones, so my current plan for Debian is to review the gtk version used when it comes to packaging wx 3.2, but if upstream's release timeline slips a lot that might not be a viable approach.

Status changed to 'Confirmed' because the bug affects multiple users.

This has finally been done in Bionic in wxwidget3.0 3.0.4+dfsg-2. GTK+ 3 packages are available in addition to GTK+ 2 packages.
