GNU GDB

QA:

gdb run : unable to find mach task port for process-id on catalina

1.3. Sign and entitle the gdb binary

1. Create a gdb-entitlement.xml file containing the following:

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
   <plist version="1.0">
   <dict>
       <key>com.apple.security.cs.debugger</key>
       <true/>
   </dict>
   </plist>

2. If the certificate you generated in the previous section is known as gdb-cert, use:

   codesign --entitlements gdb-entitlement.xml -fs gdb-cert $(which gdb)

💡 You may have to prepend this command with sudo if the gdb binary is located in a place that is not writable by regular users.
