1 On MacOSX lldb needs to be code signed. The Debug, DebugClang and Release 2 builds are set to code sign using a code signing certificate named 3 "lldb_codesign". 4 5 If you have re-installed a new OS, please delete all old lldb_codesign items 6 from your keychain. There will be 3: a code signing certification and a public 7 and private key. Reboot after deleting them. You will also need to delete and 8 build folders that contained old signed items. The darwin kernel will cache 9 code sigining using the executable's file system node, so you will need to 10 delete the file so the kernel clears its cache. 11 12 If you don't have one yet you will need to: 13 - Launch /Applications/Utilities/Keychain Access.app 14 15 - In Keychain Access select the "login" keychain in the "Keychains" 16 list in the upper left hand corner of the window. 17 18 - Select the following menu item: 19 20 Keychain Access->Certificate Assistant->Create a Certificate... 21 22 - Set the following settings 23 24 Name = lldb_codesign 25 Identity Type = Self Signed Root 26 Certificate Type = Code Signing 27 28 - Click Create 29 - Click Continue 30 - Click Done 31 - Click on the "My Certificates" 32 - Double click on your new lldb_codesign certificate 33 - Turn down the "Trust" disclosure triangle, scroll to the "Code Signing" trust 34 pulldown menu and select "Always Trust" and authenticate as needed using your 35 username and password. 36 - Drag the new "lldb_codesign" code signing certificate (not the public or private 37 keys of the same name) from the "login" keychain to the "System" keychain in the 38 Keychains pane on the left hand side of the main Keychain Access window. This will 39 move this certificate to the "System" keychain. You'll have to authorize a few 40 more times, set it to be "Always trusted" when asked. 41 - Remove "~/Desktop/lldb_codesign.cer" file on your desktop if there is one. 42 - In the Keychain Access GUI, click and drag "lldb_codesign" in the "System" keychain 43 onto the desktop. The drag will create a "~/Desktop/lldb_codesign.cer" file used in 44 the next step. 45 - Switch to Terminal, and run the following: 46 47 sudo security add-trust -d -r trustRoot -p basic -p codeSign -k /Library/Keychains/System.keychain ~/Desktop/lldb_codesign.cer 48 rm -f ~/Desktop/lldb_codesign.cer 49 50 - Drag the "lldb_codesign" certificate from the "System" keychain back into the 51 "login" keychain 52 - Quit Keychain Access 53 - Reboot 54 - Clean by removing all previously creating code signed binaries and rebuild 55 lldb and you should be able to debug. 56 57 When you build your LLDB for the first time, the Xcode GUI will prompt you for permission 58 to use the "lldb_codesign" keychain. Be sure to click "Always Allow" on your first 59 build. From here on out, the "lldb_codesign" will be trusted and you can build from the 60 command line without having to authorize. Also the first time you debug using a LLDB that 61 was built with this code signing certificate, you will need to authenticate once. 62
