Debugging in Netbeans C++ doesn't start - OSX Yosemite -

Question

I'm having trouble to make a debugging for C ++ osx Yosemite (I tried different IDE and each of them gives a problem), I read on google install gdb with brew ... but nothing. with NetBeans, launch debugging, and in the console output I get the shell gdb:

I want to debug driven by using netbeans gui, step into, step over etc .... This is a configuration of netbeans:

And I also follwed this steps to install gdb:

I had the same problem. That's what I did to fix it (under Yosemite):

1. Install brew : http://brew.sh

2. Update brew . If you already have installed brew , check for updates. In the terminal:

$ brew update

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

And after that:

$ brew update
$ brew search | grep gdb # cgdb gdb gdbm pgdbf

3. Install gdb:

$ brew install gdb

4. Codesign the binary following these instructions (similar to the ones James pointed): http://sourceware.org/gdb/wiki/BuildingOnDarwin I copy them here for the sake of completeness and to add some comments:

Creating a certificate

• Start Keychain Access application ( /Applications/Utilities/Keychain Access.app )

• Open menu /Keychain Access/Certificate Assistant/Create a Certificate...

• Choose 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 . Click several times on Continue until you get to the Specify a Location For The Certificate screen, then set Keychain to System .

• If you can't store the certificate in the System keychain, create it in the login keychain, then exported it. You can then imported it into the System keychain.

• Finally, using the contextual menu for the certificate, select Get Info , open the Trust item, and set Code Signing to Always Trust .

• 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).

And then

Giving gdb permission to control other processes

If the certificate is known as gdb-cert , just use:

 $ codesign -s gdb-cert gdb 

Comment: if gdb is not found, then add the path where it was installed. In my case:

 $ codesign -s gdb-cert /usr/local/Cellar/gdb/7.10/bin/gdb 

5. 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 .

Have you tired Codesigning the gdb executable?

The Darwin Kernel requires the debugger to have special permissions before it is allowed to control other processes. These permissions are granted by codesigning the GDB executable. Without these permissions, the debugger will report error messages such as:

 Starting program: /x/y/foo Unable to find Mach task port for process-id 28885: (os/kern) failure (0x5). (please check gdb is codesigned - see taskgated(8)) 

Codesigning requires a certificate. The following procedure explains how to create one:

• Start the Keychain Access application (in /Applications/Utilities/Keychain Access.app)
• Select the Keychain Access -> Certificate Assistant -> Create a Certificate... menu
• Then:
  • Choose a name for the new certificate (this procedure will use "gdb-cert" as an example)
  • Set "Identity Type" to "Self Signed Root"
  • Set "Certificate Type" to "Code Signing"
  • Activate the "Let me override defaults" option
• Click several times on "Continue" until the "Specify a Location For The Certificate" screen appears, then set "Keychain" to "System"
• Click on "Continue" until the certificate is created
• Finally, in the view, double-click on the new certificate, and set "When using this certificate" to "Always Trust"
• Exit the Keychain Access application and restart the computer (this is unfortunately required)

Once a certificate has been created, the debugger can be codesigned as follow. In a Terminal, run the following command...

 codesign -f -s "gdb-cert" <gnat_install_prefix>/bin/gdb 

... where "gdb-cert" should be replaced by the actual certificate name chosen above, and should be replaced by the location where you installed GNAT.
