To give gdb those permissions, you need to generate a self-signed certificate. For security reasons, this is the default behaviour. If you try debugging a file, you'll get an error since the Darwin kernel doesn't allow gdb to control another process without having special rights. Take note of the version: you'll need it later. To check out your gdb version, run: gdb -version In case you have already a newer version of gdb, you first need to unlink the other version before installing the old one.

Should you decide to do so, you can install gdb version 8.0.1 in this way. Verify that the operation was successfull by running: gdb -version To install the latest version of gdb, run this command: brew install gdb In this tutorial, I'm going to use gdb 8.3. You can either use gdb 8.0.1 or one of the latest versions, starting from 8.3. If you're using High Sierra (macOS 10.13) or later, be aware that gdb 8.1 and 8.2 are not compatible. Once you have Homebrew, you can install gdb. If you don't have it installed, open your Terminal prompt and write this command: /usr/bin/ruby -e '$(curl -fsSL )' The easiest way to install gdb is by using Homebrew: 'the missing package manager for macOS'.

To do so, a file called eclipse.ini exists in the installation directory, where this startup configuration is located. However, it is a good practice to change some configuration options for Eclipse, for example to specify in which JVM Eclipse should run, and to configure minimum and maximum memory for that JVM.

There are also links to download old Eclipse packages.Д®clipse comes in several different packages that target different users as shown in the below screenshot from the installer. Starting Eclipse Mars (version 4.5), an installer can be downloaded which guides you through the installation procedure, as opposed to downloading the whole installation as a compressed file (this option is still available, however).
