Original description
Steps to reproduce the issue:
STEP 1. Insert the following code into a blank sketch:
void setup() {
test(42);
test2(42);
}
void loop() {}
void test(int arg) {};
void test2(int arg = 0) {};STEP 2: Click the verify button and observe the error message:
DefaultArgBugDemo.cpp: In function 'void setup()':
DefaultArgBugDemo:2: error: 'test2' was not declared in this scope
STEP 3:
Examine the generated *.cpp file and observe that a prototype has been generated for test1 but not test2:
#include "WProgram.h"
void setup();
void loop();
void test(int arg);
void setup() {
test(42);
test2(42);
}
void loop() {}
void test(int arg) {};
void test2(int arg = 0) {};What is the expected output? What do you see instead?
You would expect a prototype to be generated for test2.
What version of the Arduino software are you using? On what operating
system? Which Arduino board are you using?
Tested in 0018 and 0021. Running on Win7 Home Premium (though the issue likely exists on all platforms)
Please provide any additional information below.
Of course the workaround is relatively simple (just define the prototype yourself) but it would be nice for all methods to be treated equally.
