Launching the Debugger

Using CDB

In remote mode, the local CDB process talks to a CDB process that runs on the remote machine. The process is started with special command line options that switch it into server mode. The remote CDB process must load the Qt Creator CDB extension library that is shipped with Qt Creator:

1. Install the Debugging Tools for Windows on the remote machine. The installation folder contains the CDB command line executable (cdb.exe).
2. Copy the Qt Creator CDB extension library from the Qt installation directory to the a new folder on the remote machine (32 or 64 bit version depending on the version of the Debugging Tools for Windows used):
   • \lib\qtcreatorcdbext32\qtcreatorcdbext.dll (32 bit)
   • \lib\qtcreatorcdbext64\qtcreatorcdbext.dll (64 bit)
3. Set the _NT_DEBUGGER_EXTENSION_PATH environment variable to point to that folder.
4. To use TCP/IP as communication protocol, launch remote CDB as follows:

            cdb.exe -server tcp:port=1234 <executable>

5. On the local machine running Qt Creator, select Debug > Start Debugging > Attach to Remote CDB Session...
6. In the Connection field enter the connection parameters. For example, for TCP/IP:

            Server:Port

   If you chose some other protocol, specify one of the alternative formats:

            tcp:server=Server,port=Port[,password=Password][,ipversion=6]
            tcp:clicon=Server,port=Port[,password=Password][,ipversion=6]
            npipe:server=Server,pipe=PipeName[,password=Password]
            com:port=COMPort,baud=BaudRate,channel=COMChannel[,password=Password]
            spipe:proto=Protocol,{certuser=Cert|machuser=Cert},server=Server,pipe=PipeName[,password=Password]
            ssl:proto=Protocol,{certuser=Cert|machuser=Cert},server=Server,port=Socket[,password=Password]
            ssl:proto=Protocol,{certuser=Cert|machuser=Cert},clicon=Server,port=Socket[,password=Password]

7. Click OK to start debugging.
