Can't compile on 14.04 about gradio

[haecker-felix]

You should clean your build directory (rm -r *) and restart cmake. It can be possible that a old gtk version is cached (if you installed gtk 3.20 after the cmake command)

The error messages are definitely gtk related (too old version).

But instead of breaking your system you should upgrade to 16.04 or wait until I release a flatpak (maybe snap too) for gradio (version 4.1)

I am running Ubuntu 14.04

I just tried a fresh git pull when running cmake I got:

It seems that it did find the correct GTK version installed manually

but after running make I got:

Any idea what might be wrong?

I really appreciate your help. I would very much like to try out gradio... 😄

I just tried to uninstall the old gtk3 dev package and start all over..

and with the same error. Could it be something between gtk and vala?

[haecker-felix]

Thanks for the hint :) . Yes vala could be the problem. A too old vala version delivers too old development files (vapi).

Try with a newer vala version.

[elpraga]

Thanks for the tip!

I installed the newest version of vala into the same directory as the rest of the new gtk libraries.

now it works!
