gdb在创建证书和codesign后无法在mac os下工作

Question

I have been trying to install and use gdb in mac os. I first homebrew gdb and create a certificate from the keychain i followed the steps online. I also kill the taskgated and try to codesign in the terminal. Everything seems to work, but when I tried to use gdb, I still get

Unable to find Mach task port for process-id 730: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

I also tried to run

sudo gdb <name>

I get the information like this

Starting program: /Users/leon/Desktop/os4/kitty -o o.txt in.txt
[New Thread 0x1303 of process 744]
[New Thread 0x1103 of process 744]
During startup program terminated with signal SIGTRAP, Trace/breakpoint trap.

Thank you for any help!

Answer 1

codesign all by itself doesn't do anything. You must specify what to sign and which cert to use.

The syntax is like: codesign -fs nameofcertificate /path/to/binaryexecutable

For example if you named the certificate gdbc and you are trying to sign /usr/local/bin/gdb then you would issue the following command:

codesign -fs gdbc /usr/local/bin/gdb
