Once you get the macports version of gdb installed you will need to disable SIP in order to make the proper edits to  System Library LaunchDaemons com apple taskgated plist  To disable SIP  you need to restart in recovery mode and execute the following command   csrutil disable   Then restart  Then you will need to edit the bottom part of com apple taskgated plist like this    lt array gt           lt string gt  usr libexec taskgated lt  string gt           lt string gt -sp lt  string gt   lt  array gt    Then you will have to restart to have the changes take effect  Then you should reenable SIP  The gdb command for the macports install is actually ggdb  You will need to code sign ggdb following the instructions here   https   gcc gnu org onlinedocs gcc-4 8 1 gnat ugn unw Codesigning-the-Debugger html  The only way I have been able to get the code signing to work is by running ggdb with sudo  Good luck

Here s a blog post explains it very well  http   panks me posts 2013 11 install-gdb-on-os-x-mavericks-from-source  And the way I get it working   Create a coding signing certificate via KeyChain Access  1 1 From the Menu  select KeyChain Access  gt  Certificate Assistant  gt  Create a Certificate    1 2 Follow the wizard to create a certificate and let s name it gdb-cert  the Identity Type is Self Signed Root  and the Certificate Type is Code Signing and select the Let me override defaults  1 3 Click several times on Continue until you get to the Specify a Location For The Certificate screen  then set Keychain to System   Install gdb via Homebrew  brew install gdb  Restart taskgated  sudo killall taskgated  amp  amp  exit  Reopen a Terminal window and type sudo codesign -vfs gdb-cert  usr local bin gdb

Please note that this answer was written for Mac OS El Capitan  For newer versions  beware that it may no longer apply  In particular  the legacy option is quite possibly deprecated   There are two solutions to the problem  and they are both mentioned in other answers to this question and to How to get gdb to work using macports under OSX 10 11 El Capitan   but to clear up some confusion here is my summary  as an answer since it got a bit long for a comment    Which alternative is more secure I guess boils down to the choice between 1  trusting self-signed certificates and  2  giving users more privileges   Alternative 1  signing the binary  If the signature alternative is used  disabling SIP to add the -p option to taskgated is not required   However  note that with this alternative  debugging is only allowed for users in the  developer group   Using codesign to sign using a cert named gdb-cert    codesign -s gdb-cert  opt local bin ggdb    using the MacPorts standard path  adopt as necessary   For detailed code-signing recipes  incl cert creation   see    https   gcc gnu org onlinedocs gcc-4 8 1 gnat ugn unw Codesigning-the-Debugger html or   https   sourceware org gdb wiki BuildingOnDarwin  Note that you need to restart the keychain application and the taskgated service during and after the process  the easiest way is to reboot    Alternative 2  use the legacy option for taskgated  As per the answer by  user14241  disabling SIP and adding the -p option to taskgated is an option  Note that if using this option  signing the binary is not needed  and it also bypasses the dialog for authenticating as a member of the Developer Tools group   developer    After adding the -p option  allow groups procmod and procview  to taskgated you also need to add the users that should be allowed to use gdb to the procmod group    The recipe is    restart in recovery mode  open a terminal and run csrutil disable restart machine and edit  System Library LaunchDaemons com apple taskgated plist  adding the -p opion    lt array gt       lt string gt  usr libexec taskgated lt  string gt       lt string gt -sp lt  string gt   lt  array gt   restart in recovery mode to reenable SIP  csrutil enable  restart machine and add user USERNAME to the group procmod    sudo dseditgroup -o edit -a USERNAME -t user procmod  An alternative that does not involve adding users to groups is to     make the executable setgid procmod  as that also makes procmod the effective group id of any user executing the setgid binary   suggested in https   apple stackexchange com a 112132   sudo chgrp procmod  path to gdb sudo chmod g s  path to gdb

Just spent a good few days trying to get this to work on High Sierra 10.13.1. The gdb 8.1 version from homebrew would not work no matter what I tried. Ended up installing gdb 8.0.1 via macports and this miraculously worked (after jumping through all of the other necessary hoops related to codesigning etc).

One additional issue is that in Eclipse you will get extraneous single quotes around all of your program arguments which can be worked around by providing the arguments inside .gdbinit instead.

It seems that MacPorts could be installed in El Capitan right now  https   www macports org install php Then you probably can install gdb by link you mentioned

This doesn t necessarily address the question but if you are using Mac OS X then you can probably use lldb LLDB Homepage    It s very similar to gdb and even provides a guide to using commands that you would use on gdb
