Can't you forward ports in advance and then run lldb-server in platform mode and tell it to use only those ports? Then lldb-server will do everything it needs. There is a port offset option to lldb-server that can be used in case the lldb-server that runs on the simulator returns say port 1111, but it needs to have 10000 added to it... > > I have a python script that will do this, but I need to do it inside LLDB > c++ code in GDBRemoteCommunication.cpp, so when I do a "run" it will jump > through the correct hoops and connect to the stub under simulation. > > Is there a good way to call a python script from LLDB c++ code and get a > result back?

What is stopping you from being able to do that if the answer is no? It sounds like a real hack if you have to run a python script in ProcessGDBRemote. It sounds like you need to just modify your hexagon simulator platform code to "do the right thing". > Ted > > -- > Qualcomm Innovation Center, Inc. > The Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a > Linux Foundation Collaborative Project > > > _______________________________________________ > lldb-dev mailing list > lldb-dev@lists.llvm.org > http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev _______________________________________________ lldb-dev mailing list lldb-dev@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev
