Cant compile with templates?

Hello to all,

I have written a very basic code in atmel studio Vmicro like;
Code (C++)
Select All
template <typename T>
void serial_send(T message)
{
   Serial.print(message);
}

void setup()
{
	Serial.begin(9600);
	serial_send("Hello World");
}

void loop()
{

}


After I tried to compile this, I got errors like
Quote:

Error            2:18: error: variable or field 'serial_send' 
Error            2:18: error: 'T' was not declared in this 


But I can compile with Arduino IDE succesfully by opening ino file that this project created. 
What is the problem?

Thanks for the report and detail.

This is an issue with the automatic prototype generation in Visual Micro.

We will investigate further, and in the meantime, you can add the below prototype above the first line:-
Code
Select All
template <typename T>void serial_send(T message);


Then add a Local Board.txt to the project (Right Click project in Solution Explorer, Add > Local Board.txt), and add the below line to that file:-
Code
Select All
vm.ctags=false


This should allow it to build while we investigate the full resolution further.
