The following C++ code is for Intel TBB. This code was generated by the Flow Graph as well. I have 2 compilation errors: 

No matching function for call to 'make_edge'
No matching function for call to 'make_edge'

Here is code with definitions: 

 function_node< tbb::flow::tuple<char *,char *>, char * > result_reporter(position3_g0, 1, []( const tbb::flow::tuple<char *,char *> & in ) -> char * {...

function_node< char *, char * > sott_target_node(position3_g0, unlimited, []( char *buffer ) -> char * {

Here is the TBB calling code that creates the compilation errors

make_edge( result_join, result_reporter);

make_edge( sott_target_node, input_port< 2 >( result_join ));

I would glady provide all the code but StackOverflow prevent too much code with little description. Can any one help out figure out these errrors? Thanks

You are trying to use the input of the function_node incorrectly. A function_node with an input of tuple<char *, char *> takes a predecessor with a tuple<char *, char *> output.

If this is what you want (that there be two inputs to the node each of char * type, and an output of char *) you should use a combination of an indexer_node (which has multiple input ports, and any input on any port will cause a message to be emitted with the port number and the input wrapped) that connects to a function_node that takes the output type of the indexer_node. Please see the documentation, and ask if you have any questions.

  • If you need the node to only be fired when it receives an output from all of its predecessors, You need a join_node. https://software.intel.com/en-us/node/506236 . There are three policies for joining; I'd guess you want a queueing join. The indexer_node immediately forwards each message it receives from each port; the join waits until it has at least one input at each input port before it forwards them. The output of the join is a tuple. – cahuson Jan 02 '17 at 18:01
