[Kicad-developers] m_graph is null when exporting netlist

[Jeff Young]

Hi Jon,

When we try to build a netlist for Update PCB from Schematic we get an assert 
in NETLIST_EXPORTER_GENERIC::makeListOfNets() because m_graph is null.  Is this 
because real-time updating is turned off?  Is there a call to build it that we 
should be making in the meantime?

Cheers,
Jeff.

The graph should be updated before netlisting even if real-time is turned
off.  What is the call stack where you get the assert?  I'm not a build
machine now so I will be of limited use, but it sounds like somehow the
exporter is being constructed without setting the pointer to the global
connection graph object.

Re: [Kicad-developers] m_graph is null when exporting netlist

[Jeff Young]

It’s in the cross-probing code.  The init looks like this:

NETLIST_OBJECT_LIST* net_atoms = BuildNetListBase();
NETLIST_EXPORTER_KICAD exporter( this, net_atoms );
STRING_FORMATTER formatter;

exporter.Format( &formatter, GNL_ALL );

payload = formatter.GetString();

[Jeff Young]

I see there are other places where it’s constructed with the global 
g_ConnectionGraph.  Do I just need to add that?

Re: [Kicad-developers] m_graph is null when exporting netlist

[Jon Evans]

Yes, try that.  We can probably pull it out of the ctor and just use the
global until/unless it is refactored away.

[Jeff Young]

Yep, seems to have worked.  Thanks!
