| Running as root seems to work well:
| |
| m@viper:~/development/causam/git/np/nop-bigress-client-c$ sudo cmake-release/nop-client -d7
| |
|
| |
| Better, we should be able to allow the binary access to lower ports with setcap:
| |
| sudo setcap CAP_NET_BIND_SERVICE=+eip /home/m/development/causam/git/np/nop-bigress-client-c/cmake-debug/nop-client
| |
| # that will stick - except you have to rerun that every time after building it
| |
| # turn it off with
| |
| sudo setcap CAP_NET_BIND_SERVICE=-p /home/m/development/causam/git/np/nop-bigress-client-c/cmake-debug/nop-client

| Qt Creator seems pretty good.
| |
|
| |
| Install DEBUG versions of all libraries into /usr/local - see build_lws_debug for an example of that library.
| |
|
| |
| Make sure you rebuild everything from command line, it took a couple times before Qt seemed to pick it up and debug into libs. You should NOT have to add any paths directly.
