Topic: IDE 1.6.3 is now available for download (Read 2521 times) previous topic - next topic


Hi all,
I found in this version (1.6.3) a compiler's bug: easily the compiler crashes returning the error

collect2.exe: error: ld returned 5 exit status

I use WinXP SP3.

This is an example of code that creates the condition. I made many tests, the problem seems not caused by a "special" command or function.

Code: [Select]

  This sketch makes a compiler's crash (IDE ver. 1.6.3.,
  on WinXP SP3).
#include <LiquidCrystal.h>
#include <Bounce.h>

const unsigned int BUTTON_PIN=8;
const unsigned int LED_PIN=9;
const unsigned int DEBOUNCE_DELAY=20;
unsigned long time;  //uint32_t

LiquidCrystal lcd(2, 3, 4, 5, 6, 7);  // RS, En, D4, D5, D6, D7

void setup() {
  pinMode(LED_PIN, OUTPUT);
  lcd.begin(16, 2);  //(columns, rows)

void loop() { 
  lcd.setCursor(8, 1);
  time = (millis()/1000);
  if (button.update()) {
     if (button.read() == HIGH) {
     digitalWrite(LED_PIN, HIGH);     
     else {
       digitalWrite(LED_PIN, LOW); 

(For use this code you need to install Bounce library (download here) and you need to change in .h and .cpp files #include "Arduino.h" instead of "WProgram.h")

An older IDE version (e.g. 1.0.5) works properly; this code is compiled without errors.


Westfw about restart problem

Global variable:  char cbuf[5];                           //Character buffer array

Also want to agree with TerryKing:

"It would be ideal if the IDE positioned the first error message in top of the visible area.

Everything else seems great! Thanks!"

PS: right now, you should be able to create a "portable" 1.6.3 installation on an internet-connected computer, and then transfer that to your non-connected computer.


thank you for the workaround and the issue on github.

Ciao a tutti,
IDE 1.6.3 e 1.6.2 non funziona su Windows 7
mentre la versione IDE 1.6.1 viene eseguito in modo corretto.
avete suggerimenti nel merito ?


I had no problems with it, though havent tested my DUE yet ( though installation of board seemed to have gone smooth) and older sketches with libraries seem to work well. Seems like a great improvement.
One honest question i have, as a confused user, is : Are there any differences affecting any of the boards by this 1.6.3 Version of the IDE and the arduino.org's 1.7.2 ?! I hear of boards giving up warnings and the likes ?!
I hope another knowledgeable user can enlighten this confused user, without the constraints of legal disputes.
* For the record, i think this community is what always made up the ARDUINO name  and THAT no one can disprove in court ;)
