Library doesn't seem to work with Arduino Due

[apalazzi]

#include <utility.h>
#include <unwind-cxx.h>
#include <system_configuration.h>
#include <StandardCplusplus.h>
#include <vector>
#include <map>

std::vector<int> myvec;
std::map<String, int> mymap;

void setup()
{
  myvec.push_back(1);
  mymap["test"] = 2;
}

void loop() {}

When compiling for Arduno Due this gives the following error:

Arduino: 1.5.4 (Windows 7), Board: "Arduino Due (Programming Port)"

Additional info: Arduino IDE 1.5.4 ; when compiled for Arduino Mega 2560 it works.

[fawques]

It doesn't work either with my Arduino DUE, but with different error messages. I show the full compilation messages:

• When trying to compile the example string_vector:

Arduino: 1.5.6-r2 (Windows 8), Placa:"Arduino Due (Programming Port)"

I have the same error as fawques, but after adding the flag -fpermissive to the boards.txt file, the error message turned to something similar to apalazzis message.

Has anybody found a way to fix this (by e.g. an alternative build process)?

[esel7353]

I have found a way to get it compiled (probably a very, very bad one). I'm working on ubuntu 14.04 with arduino IDE 1.6.1:

1. open ARDUINO_INSTALLATION/hardware/arduino/sam/boards.txt and add the -fpermissive flag, so that the two lines with "extra_flags" read:

   arduino_due_x_dbg.build.extra_flags=-fpermissive -D__SAM3X8E__ -mthumb {build.usb_flags}
   

   and

   arduino_due_x.build.extra_flags=-fpermissive -D__SAM3X8E__ -mthumb {build.usb_flags}
   

2. open ARDUINO_INSTALLATION/libraries/StandardCplusplus/unwind-cxx.h. Make the lines 175-183 a comment and add the line

   const _Unwind_Exception_Class __gxx_exception_class = "GNUCC++\0";
   

Honestly I have no idea what I did there (my c++ knowledge is limited). So this might be a very bad workaround.

[AppliedEM]

Having the same error with the ESP-12. Has anyone found a workaround that doesn't involve compiling with -fpermissive?

This project is dead. I have a replacement you can install using the Arduino Library Manager:

Fixed now in 41b4465634e34fce8e010386bd80f9a371c6b311. Running great on my Due
