I have installed eclipse for embedded c/c++ developers on Ubuntu 20.04, and it couldn't be launched the first time, but the next time, when I went to the installation directory, double clicked the icon, it was prompted:
and it hasn't made start menu entry and desktop shortcut even when I checked the 2 items when installation.
I found solution: first, I downloaded the wrong package, it should be "eclipse-embedcpp-2020-12..." second,
sudo tar xzf eclipse-embedcpp* -C /usr/share
, thensudo chmod +x eclipse
, then./eclipse
