Where to get gtk3?:

WARNING: unit search path does not exist: /usr/share/lazarus/1.6.4/lcl/units/x86_64-linux/gtk3

for Debian 8.8-64 GNOME3

Have you tried to rebuild your Lazarus to support GTK 3?
To do it:
Lazarus main menu > Tools > Configure Build Lazarus > on LCL widget type, choose GTK 3 (alpha) > Click the "Build" button > wait several minute ...

It does not want to rebuild. It looks like gtk3 (for Lazarus) is not ready yet.

If you got linking errors, make sure the devel libraries for GTK3 are installed.

I've tried to rebuilt it using GTK 3. It succeed but needs some works.

The first error I got said OpenGLContext wasn't supported by ... (duh I forget). So I uninstall lazopenglcontext 0.0.1 package. And rebuilt again.

But I got a permission error. So I started my Lazarus using sudo lazarus-ide and rebuilt. No error anymore.

But because I built it using root account, now I get a dialog telling me there are multiple Lazarus when starting the IDE.

Does my GTK 3 work correctly? I don't know but at least I managed to rebuild without error.

You can the setting I used to rebuilt Lazarus using GTK 3 and the multiple Lazarus warning dialog on the images below.

I forgot to mention:
- UbuntuMate 16.10 64-bit
- Lazarus 1.6.4
- FPC 3.02

Don't build with sudo.
A new executable is built under your user dir ~/.lazarus if the original one is write protected.
"startlazarus" is clever enough to know which executable should be started.
That's the idea anyway. Does it work for you?

BTW, I did not know GTK3 bindings are good enough for building the whole IDE.
I must test it when I have time.

If I didn't build it using sudo, I get permission error. But I never tried using startlazarus.

I don't think GTK 3 works on my test. Because the splash screen still showing GTK 2.

It also says 1.6.4..... For GTK3 to work you need 1.8 or 1.9

I've just found this explanation how to enable GTK3 interface:
http://wiki.lazarus.freepascal.org/GTK3_Interface

I think my test failed because I haven't installed GTK 3 and I didn't uncomment that "USEGTK3ALPHA".

Anyway, which GTK 3 should I install? There are 5 gtk3 things showed on my Synaptic Package Manager:
- gtk3-engines-breeze
- gtk3-engines-unico
- gtk3-engines-xfce
- ~~gtk3-im-libthai~~ (not this one, it's for Thai language)
- gtk3-nocsd

These are gtk3-engines for theming, this is not what you need. gtk3 libraries are installed by default since a long time. For using gtk3 apps, just check you have libgtk-3-bin,libgtk-3-0 and libgtk-3-common. For building for gtk3, add libgtk-3-dev

Code: Bash [Select][+]

/usr/share/lazarus/1.6.4/lcl/units/x86_64-linux/gtk3

As I explained:
"It also says 1.6.4..... For GTK3 to work you need 1.8.X (stable) or 1.9 (trunk)"
There have been a considerable amount of changes. You will probably also need FPC 3.0.4.

Please upgrade first. Then report back.
