Question: what does CEF use libatk-bridge2.0 for?

Postby rigorberto » Wed Sep 30, 2020 1:49 pm

I need to use it for an older Linux distro (lucid lynx), which will run Chromium just fine, but it will complain of a missing libatk-bridge2.0 which I can't install simply by sudo apt-get-ing it like I can with a 32 bits version of Linux Mint.

What is it used for, if Chromium itself doesn't require it?

The libatk-bridge dependency comes from Chromium. Where are you getting the Chromium build that works fine? Is it the same Chromium version? If the build is from a distro, then they're likely applying distro-specific configuration or patches. You could try making a local CEF build with those same changes.

I just installed it with apt-get install chromium-browser.

The sample CEF app from this link here:
http://opensource.spotify.com/cefbuilds/index.html

Asks for a libatk-bridge2.0 shared library. No problem at all installing it on newer distros with active repositories, but why would Chromium run, but not CEF, because of a lib that chromium itself does not use?

Because you're likely installing a special Chromium build specifically prepared for your distro. What is the Chromium version?

"Lucid Lynx" is Ubuntu 10.04. I would be very surprised if any modern Chromium versions run on it.

25.0.1364.160 (CEF in the windows and linux 64 bit version of my app is 83.0.4103.106 ), but if a just as old version of Mint has no trouble running the CEF sample application, it should be possible to run it on this one too.

That is indeed a very old Chromium version. An equally old version of CEF would probably run. However, if you want to use a newer CEF version then you also need to use a supported distro version (currently Ubuntu 14.04 or newer).

What Mint version are you using?

If I'm not mistaken, I tested a pretty recent build of the CEF sample app on Linux Mint 12. I didn't have to jump through hoops to get it working the same way I'm having to with another distro that came around the same time.
