For convenience, version 5.1.1 of the plug-ins is also available as Eclipse packages, which pack together the Eclipse IDE for C/C++ Developers standard distribution (Eclipse 4.16) with the Eclipse Embedded CDT plug-ins.
macOS security notice
On macOS, if you download the archive with the browser, the strict security checks on recent macOS will prevent it to run, and complain that the program is damaged. That’s obviously not true, and the fix is simple, you need to remove the com.apple.quarantine extended attribute.
$ xattr -c ~/Downloads/eclipse-embedcdt-2020-06-R-macosx.cocoa.x86_64.tar.gz
After un-archiving, if the application still complains, check/remove
the attribute from the
Eclipse.app folder too:
$ xattr -cr ~/Downloads/Eclipse.app
