1.20.4: configure fails with missing `gtk+-3.0` when is running in build env with gtk4 only

Yeah looks like it is the same issue like in https://gitlab.gnome.org/GNOME/NetworkManager-pptp/-/issues/6

configure: error: Package requirements (gtk+-3.0 >= 3.16) were not met:

Package 'gtk+-3.0', required by 'virtual:world', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Thanks for the NetworkManager-pptp issue link. For consistency, I'll wait and do whatever NetworkManager-pptp does for the fix.

[dkosovic]

I suspect they are taking their time with the upstream NetworkManager VPN clients to build in a gtk4 only build env because almost all Linux distros still ship with the gtk3 based nm-connection-editor which is part of the network-manager-applet source :

• https://gitlab.gnome.org/GNOME/network-manager-applet

The non-libnma parts of network-manager-applet (i.e. applet and editor) have not been ported to gtk4. I guess once nm-connection-editor has been ported to gtk4, they'll update the NetworkManager VPN clients to allow building in a gtk4 only build env.

I'm still keeping an eye out on the upstream NetworkManager VPN clients, once any of them support a gtk4 only build env, I'll do the same as whatever they do.

[kloczek]

Any update? 🤔

[dkosovic]

I haven't seen any upstream changes yet.

I noticed the corresponding NetworkManager-pptp issue #6 was closed with the following message :

This works as intended -- the gtk3 build is enabled by default.

You need to pass --without-gnome to configure to disable it.

in the configure.ac code I see:

if test x"$with_gnome" != xno; then
    PKG_CHECK_MODULES(GTK, gtk+-3.0 >= 3.16)
    GTK_CFLAGS="$GTK_CFLAGS -DGDK_VERSION_MIN_REQUIRED=GDK_VERSION_3_16"
    GTK_CFLAGS="$GTK_CFLAGS -DGDK_VERSION_MAX_ALLOWED=GDK_VERSION_3_16"

    PKG_CHECK_MODULES(LIBNMA, libnma >= 1.8.0)
    PKG_CHECK_MODULES(LIBSECRET, libsecret-1 >= 0.18)
fi

if test x"$with_gtk4" != xno; then
    PKG_CHECK_MODULES(GTK4, gtk4 >= 4.0)
    GTK4_CFLAGS="$GTK4_CFLAGS -DGDK_VERSION_MIN_REQUIRED=GDK_VERSION_4_0"
    GTK4_CFLAGS="$GTK4_CFLAGS -DGDK_VERSION_MAX_ALLOWED=GDK_VERSION_4_0"
    PKG_CHECK_MODULES(LIBNMA_GTK4, libnma-gtk4 >= 1.8.33)
fi

I suspect the PKG_CHECK_MODULES(LIBSECRET, libsecret-1 >= 0.18) package check should still be performed when --without-gnome and --with-gtk4 are used.

[dkosovic]

I'll close this as the corresponding NetworkManager-pptp issue #6 was closed.

Would have preferred that they were more consistent in the naming of the flags between gtk3 and gtk4, but will stick to whatever upstream NetworkManager project does.
