Steve,
I am glad to hear that you are now able to run GNU Radio Companion there.
I am not familiar with the internals of GTK and GObjects and I can't really
help you there.
However this morning I ran GRC on a simple FM receiver example I have, and I
used strace to track the calls to 'execve':
strace -f -e execve -o /tmp/grc.trc gnuradio-companion FM-Receiver-RSPdx.grc
The output from 'strace' here shows only these processes being launched
directly by GRC:
6439 execve("/usr/local/bin/gnuradio-companion", ["gnuradio-companion",
"FM-Receiver-RSPdx.grc"], 0x7ffc04bea340 /* 75 vars */) = 0
6450 execve("/bin/gsettings", ["gsettings", "get",
"org.gnome.desktop.interface", "gtk-theme"], 0x55652906a3d0 /* 75 vars */) = 0
6456 execve("/usr/bin/python3", ["/usr/bin/python3", "-uc", "import runpy;
runpy.run_path('/u"...], 0x55652906a3d0 /* 75 vars */) = 0
6529 execve("/usr/bin/python3", ["/usr/bin/python3", "-u",
"/home/franco/SDR/gr-sdrplay3/exa"...], 0x55652906a3d0 /* 75 vars */) = 0
I don't see GRC launching other additional processes directly; in my case some
of processes you show in your message are part of the OS common services (for
instance here I see a service called 'dbus-broker').
