Use either gdb or the path where gdb was installed (for example, /usr/local/Cellar/gdb/7.10/bin/gdb) in the menu /Netbeans/Preferences/C/C++/Build Tools field Debugger Command field.

If you try to use gdb without signing it you will likely receive this message: Unable to find Mach task port for process-id 28885: (os/kern) failure (0x5). From a Terminal session: brew install gdb gdb (gdb) quit. In my case: $ codesign -s gdb-cert /usr/local/Cellar/gdb/7.10/bin/gdb The following instructions assume you have installed homebrew on your Mac. Install gdb via Homebrew: brew install gdb Restart taskgated: sudo killall taskgated & exit Reopen a Terminal window and type sudo codesign -vfs gdb-cert. If the certificate is known as gdb-cert, just use: $ codesign -s gdb-cert gdbĬomment: if gdb is not found, then add the path where it was installed. And the way I get it working: Create a coding signing certificate via Ke圜hain Access: 1.1 From the Menu, select Ke圜hain Access > Certificate. Giving gdb permission to control other processes You must quit Keychain Access application in order to use the certificate and restart taskgated service by killing the current running taskgated process (comment: for example with sudo pkill taskgated or restarting). You can then imported it into the System keychain.įinally, using the contextual menu for the certificate, select Get Info, open the Trust item, and set Code Signing to Always Trust. If you can't store the certificate in the System keychain, create it in the login keychain, then exported it. Click several times on Continue until you get to the Specify a Location For The Certificate screen, then set Keychain to System. Open menu /Keychain Access/Certificate Assistant/Create a Certificate.Ĭhoose a name ( gdb-cert in the example), set Identity Type to Self Signed Root, set Certificate Type to Code Signing and select the Let me override defaults. Start Keychain Access application ( /Applications/Utilities/Keychain Access.app)

Codesign the binary following these instructions: I copy them here for the sake of completeness and to add some comments:.

$ brew search | grep gdb # cgdb gdb gdbm pgdbf This step turned out to be decisive for me as, before updating, brew did not find any gdb package: $ brew install gdb # Error: No available formula for gdb If you already have installed brew, check for updates. That's what I did to install GDB (under Yosemite):
