opencpn and gtk3

[seandepagnier]

I decided to try using gtk3 which should in theory improve over gtk2.

I found a bunch of minor annoyances, mostly asserts failing, and some weird colors in the dialogs, but opencpn remains completely usable.

Anyone else tried this?

I just tried to use GTK3 on my Debian unstable 64bit. While it builds it fails to start because the resulting binary has both GTK2 and GTK3 symbols. The problematic shared library seems to be libgtk-x11-2.0.so. Interestingly, this is not explicitly listed when the binary is linked.

For now I switched back to GTK2, but I might try again over the next couple of days.

SethDart's Fedora packages for O4.1 are using wxGTK3 for some time already as there is no wxGTK2 in the newest Fedora releases.

For the record, my self-compiled opencpn is currently linked against libs from libgtk2.0-0 and libwxgtk3.0-0v5. Note that the latter is wxwidgets 3.0.2+dfsg-1.2 using GTK2.

To my knowledge, wxGTK3 is built with GTK2 on Debian/Ubuntu while it's built with GTK3 on Fedora.

According to https://packages.debian.org/unstable/libwxgtk3.0-0v5
dep: libgtk2

Fedora: wxGTK3-3.0.2-12.fc23.x86_64.rpm | RPM Info | koji
libgtk-3.so.0()(64bit)

BTW, on Fedora, there's a compat-wxGTK3-gtk2 package available. Maybe there's a libwxgtk3-gtk3 package laying somewhere.

You cannot mix dependencies built with gtk2 with others built with gtk3
