Debugging of the C++ ICE nodes

[jipo]

Hi,

i want to discuss possibilities/workflows in C++ custom ICE development. More sofisticated nodes need clever workflow how to debug the code...

1) is it possible to setup debugger and use standard method using breakpoints? I am relatively skilled C++ developer, but I haven't a lot of exterience with the Visual Studio (and it's debugger)
2) tracing from the ice node? I tried Appliocation().LogMessage() but i don't see my messages in the history,it is strange...
3) other more advanced debugging workflow?

1) Yes, in VS go to Tools->Attach to process and select the XSI process ( you need to compile in the debug mode for using this feature ), then you can start use your node from XSI with all breakpoints
2) >>I tried Appliocation().LogMessage() but i don't see my messages in the history,it is strange...
Its really strange, did you try to explicitly use messagetype enum ? like Application().LogMessage( "some info here", siInfoMsg ) , you can also use siWarningMsg \ siErrorMsg since it is more observably

When i remember right, LogMessage on output ports only works when the port is connected and ShowValues is active.

thanks guys,

yes, LogMessage (and ice node itself) is executed only when an output value is used. it is not executed when it is only connected to the "Set Data" node.
"Show value" only forces evaluation.

ICE optimalisations are aggressive:-)
