Codesign gdb on OSX

Jul 7, 2016 · Gian Sass

Trying to use gdb on OSX El Capitan gave me following message.

You need to codesign gdb with a custom certificate.

Open Keychain Access
In the menu, go to Certificate Assistant -> Create Certificate
Choose an appropriate name like gdb-cert, set Identity Type to Self Signed Root, set Certificate Type to Codesign, and check Let me override defaults
Optional: extend duration
Click continue until specifying location for the certificate, choose System
In System, click on gdb-cert, choose Get Info, go to Trust and set Code Signing to Always Trust
Restart taskgated
```
sudo kill -9 (which gdb)
```
