RAD STUDIO BUILD Embarcadero® RAD Studio 10.3 Version 26.0.33219.4899 (10.3.1)

Ubundu 16.04 ubuntu-16.04.6-desktop-amd64.iso

Can you tell me if you manage to run this example and if so what version of RAD STUDIO you used and what version of Linux

[Eugene Kryukov]

First try to update SDK in Delphi. Second, install GTK3 to Ubuntu by “sudo apt install libgtk-3-common“ and then update SDK in Delphi again.

I installed libgtk-3-common then i updated the SDK but the problem remains can you tell me what version of Ubuntu Linux you use and which version of delphi ? does it work for you?

[Eugene Kryukov]

We use Ubuntu 16.04, 18.04 and it works with Delphi 10.3.1.

Please check your Linux’s SDK (usr\lib\x86_64-linux-gnu sub-folder usually) folder for “libgtk-3.so” file. Or any combination, like “libgtk-3.so.0” etc.

OK I managed to resolve the problem with this command at the Linux Ubundu ===> “sudo apt-get install libgtk-3-dev”

the command you gave me “sudo apt install libgtk-3-common“ did not solve the problem i had to install the dev edition of the GTK

so what i did to resolve the problem was “sudo apt-get install libgtk-3-dev” then i had to update the SDK cache clicking replace yes to all.

this solved the problem please tag the issue as resolved.

Thank you
