I'd like to debug my program through eclipse-cdt or emacs. But, now both of them fail because gdb is not certificated yet in Yosemite.

My gdb installation status is here. I installed gdb through home-brew.

dplee@dpleeui-MacBook-Pro ~/w/fish-shell> uname -a

If I execute gdb, I continue to encounter the same error message as below.

(gdb) b main
Breakpoint 1 at 0x10020b9a9: file fish.cpp, line 512.
(gdb) r
Starting program: /Users/dplee/work/fish-shell/fish 
Unable to find Mach task port for process-id 719: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))
(gdb)

I followed these guide lines, but I can't restart task gated because it's process id is 0.

Is there anyone who has already faced through this issue and is using eclipse and emacs debugging functions with gdb? I really like to use gdb with emacs in MacOS.

I found the answer here about eclipse with gdb in MacOS Yosemite.

In brief, the gdb team almost stopped updating gdb in os x and supporting only lldb. Many c++ developers are having trouble with this issue. Some of them are moving to Xcode, but they say it's not so nice IDE as eclipse-cdt.

If you still want to use eclipse as your debugger, there's one way you can try. Here is Jim Knarf's comment. (See Comment #23)

You need to download GDB source code from http://www.gnu.org/software/gdb/download/
Then after building it, you will need to "sign" the application with appropriate certificate, and reboot the system before you can use it. See https://sourceware.org/gdb/wiki/BuildingOnDarwin about how to use 'codesign' and 'task gated' commands.

Here are the steps you need to take:

1. download gdb source code
2. become root (su command)
3. build the application using configure, make, and make install commands
4. put the new gdb application to /usr/local/bin
5. vi /System/Library/LaunchDaemons/com.apple.taskgated.plist
      change option -s to -sp
      and save the file
6. spctl --master-disable
7. create 'gdb-cert' certificate in System using Keychain Access application
8. codesign -s gdb-cert `which gdb`
9. restart the computer.

Now you can use gdb as a standalone debugger or use it in Eclipse.

If you want to use lldb in eclipse, this can be your another option. https://github.com/freedib/lldbmi2
