GDB kind of doesn't work on macOS Sierra

Question

It is a problem that appeared when I first updated to macOS Sierra yesterday.

GDB itself is running OK. However, somehow, it cannot run my program. When I type \'run

Answer 1

assume your MacOS version is 10.12.6.

1. upgrade your gdb to version 8.0.1 brew upgrade gdb
2. execute echo "set startup-with-shell off" >> ~/.gdbinit ( I saw this command when I installed gdb by brew )
3. create a certificate with name gdb-cert and trust this certificate in code signing option
4. reboot your mac
5. execute sudo codesign -s gdb-cert /usr/local/bin/gdb
6. done! have a fun ~

BTW,you can use lldb to replace gdb .
