During startup program terminated with signal ?, Unknown signal. Unexpected GDB output from command '-exec-run'.

Now I no longer get the taskgated/codesigning error but the debugger just quits, similarly to benoitgoyet post above. I then tried using these steps (using entitlements) I also created a new certificate and tried again but no difference. /configure -prefix/opt/local -program-prefixi386-elf-targeti386-elf -with-gmp/opt/local -with-libelf/opt/local -with-build-libsubdir/opt/local make sudo make install Then the i386-ELF GDB will be installed in /opt/local with program name i386-elf-gdb. Unable to find Mach task port for process-id 1510: (os/kern) failure (0x5). Unexpected GDB output from command '-exec-run'. GDB, the GNU Project debugger, allows you to see what is going on 'inside' another program while it executes - or what another program was doing at the moment it crashed. With GDB 8.2.1 (through Homebrew) and the steps above (without the Enable Root User) I still keep getting the code sign error in Mojave and GDB: ERROR: Unable to start debugging. Debugging with gdb should now work as expected.

Modify System Integrity Protection to allow debugging: csrutil enable -without debug.

Shut down your mac and restart in recovery mode (hold down command-R until apple logo appears).

Codesign gdb using your certificate: codesign -fs gdbc /usr/local/bin/gdb.

Enable root account by following the steps given below:.

Restart taskgated in terminal: killall taskgated.

Expand Trust, set Code signing to Always Trust.

Find the certificate in System keychain.

Create certificate and close Certificate Assistant.Set Location to Login, Unlock System by click on the lock at the top left corner and drag and drop the certificate gdbcert to the System Keychain. If this yields the following error:Ĭertificate Error: Unknown Error =-2,147,414,007 The same applies to the process of uninstalling Homebrew. This method is the easiest and it’s recommended by the Homebrew team. Continue until 'Specify a Location For' Moving to the main part install Homebrew Mac we should explain that the installation method we describe uses curl to download the installation script.In menu, open Keychain Access > Certificate Assistant > Create a Certificate.To fix this error, follow the following steps: (please check gdb is codesigned - see taskgated(8)) Unable to find Mach task port for process-id 2133: (os/kern) failure (0x5).

Install gdb for mac
