error compile when define ISR routine for external interrrupt

[vlad2005]

I got an error when i try to implement in ISR for external interrupt:

09:30:12 Building the project | Processing...
.pioenvs/optibootPro16MHzatmega328/libFrameworkArduino.a(WInterrupts.o): In function `__vector_2':
collect2: error: ld returned 1 exit status
09:30:16 ERROR | it took 4.49s

Here is implementation

#ifdef EXTERNAL_INTERRUPT
ISR(INT1_vect) {
  CounterControl::GATE_ISR();
};

void CounterControl::GATE_ISR() {

}
#endif

Which board are you using megaatmega2560?
If don't, please upload your platformio.ini

I've added the setup and the loop and it compiled without problem

#ifdef EXTERNAL_INTERRUPT
ISR(INT1_vect) {
  CounterControl::GATE_ISR();
};

void CounterControl::GATE_ISR() {

}
#endif

void setup()
{

}
void loop()
{

}

i don't use atmega 2560
Anyway, is very strange. In same file i have another precompile condition for another ISR (pin change interrupt) and compile without any problem.
In fact my cpp file contain two implementation. One for pin change interrupt and another for external interrupt. Both have same structure. When define pin change interrupt i don't have any error. When define external interrupt i got this error.
platformio.ini

[env:optibootPro16MHzatmega328]
platform = atmelavr
framework = arduino
board = optibootPro16MHzatmega328
[platformio]
src_dir = /home/dev/Arduino/test/Gate

here is board config

Remove package, delete all files and reinstall deviot with platformio 3.0.1. I have same problem.

L.E.
I try to compile same project using Arduino IDE. Also i got an error, so i think that is not related to deviot package.
Here is error:

WInterrupts.c.o (symbol from plugin): In function `attachInterrupt':
(.text+0x0): multiple definition of `__vector_2'
sketch/CounterControl.cpp.o (symbol from plugin):(.text+0x0): first defined here
collect2: error: ld returned 1 exit status
exit status 1
Error compiling for board [Optiboot] Arduino Pro Mini 5V 16Mhz w/ ATmega328.

[vlad2005]

Solved!
It's seem that EXTERNAL_INTERRUPT is used in some libraries. I change name to EXT_INTERRUPT and now project compile without error.
It is not a issue relating to Deviot package.
I apologize for the inconvenience!

L.E. Pfuffff! Now i found real problem. Because i use RCSwitch library witch work on external interrupt pin, obviously here are some implementation for ISR routine. When i try to re-implement same routine i got error. Everything compile fine if remove RCSwitch library. So it's an conflict with that library.

Good to hear!

As recommendation, I realized your JSON file hasn't the right format, in PlatformIO 3 it should be like this:

{
    "build": {
        "core": "arduino",
        "extra_flags": "-DARDUINO_ARCH_AVR -DARDUINO_AVR_PRO",
        "f_cpu": "16000000L",
        "mcu": "atmega328p",
        "variant": "eightanaloginputs"
    },
    "frameworks": ["arduino"],
    "name": "Arduino Pro Mini Optiboot ATmega328 (5V, 16 MHz)",
    "platform": "atmelavr",
    "upload": {
        "disable_flushing": true,
        "maximum_ram_size": 2048,
        "maximum_size": 32256,
        "protocol": "arduino",
        "require_upload_port" : true,
        "speed": 115200
    },
    "url": "http://arduino.cc/en/Main/ArduinoBoardProMini",
    "vendor": "Arduino"
}

Rename the json file as: optibootPro16MHzatmega328.json That way you will avoid any problem

[vlad2005]

Yes, is truth! After i make update i see that not working with old json and need to do exactly what u say (after many try's). Maybe is better to make an update to this threat to help and other users.
