using the latest Arduino IDE, I try to define a callback type that will be lambda compatible like...

typedef std::function<void(float progress)> AnimUpdateCallback;

and I get a compile error about std.

Hello,

I'm currently trying to use your library to make a school project, and I prefer to use vectors instead of double-sized array. It worked well on my last project (made last week), but now, when I try to add the vector library, I get the following errors :

C:\Users\benoit\Documents\Arduino\libraries\StandardCplusplus/vector:43:94: error: macro "swap" passed 4 arguments, but takes just 2

template <class T, class Allocator> void swap(vector<T,Allocator>& x, vector<T,Allocator>& y);

                                                                                          ^

C:\Users\benoit\Documents\Arduino\libraries\StandardCplusplus/vector:520:106: error: macro "swap" passed 4 arguments, but takes just 2

template <class T, class Allocator> _UCXXEXPORT void swap(vector<T,Allocator>& x, vector<T,Allocator>& y){

Il works well with the example file and my previous project, so I don't know what to do...

I just include the standardCplusplus.h and vector headers at beginning of my .ino file.

I got compilation errors due to a macro (abs) defined in Arduino.h. Encapsulating the inline definition of the abs() function in the cstdlib header, in #ifndef ... #endif directives fixed this issue. I hope I didn't break anything else in the meantime...

After copying files into the /Arduino/libraries/StandardCplusplus folder, IDE returns a compilation error because some operators are defined twice (with Arduino 1.0.4).
The solution I've found to bypass the problem is to delete the following files:

• StandardCplusplus / new_opv.cpp
• StandardCplusplus / del_opv.cpp

Hope it helps

When I try to throw a logic_error, I am given an error saying: namespace "std" has no member "logic_error". I have included the stdexcept header.

I'm trying to use this library and hitting a problem. Below is the (verbose) output. I did notice that the StandardCplusplus.h include does an #undef abs, which I'm assuming is related to this, but including that file or not made no difference in my project. Any ideas?...thanks in advance.

Hello, how do I convert an int to a string using standardcplusplus?

I tried the conventional way of using stringstreams, but it gives an error:

std::string itoa(int arg) {
stringstream aa;
aa << arg;
return aa.str();

}

The error reported is error: 'string' does not name a type.

I don't know why I got this, and I didn't #include any of the files listed anywhere. I hope these are helpful.

It seems like there are some compilation problems related to the istream and ostream classes. I don't think it is related to my code. I get the following errors just after the compiler says the following:

Hello. I'm pretty new to using this library, but I hope my question is in the right place. I'm trying to use unordered_map in my sketch, but I'm seemingly unable to get it to compile. Is unordered_map supported? Is there some step I've missed? Thanks in advance!

The implementation of basic_serialbuf treats having no characters available as an EOF condition. It expects that read() and peek() are blocking as they would be in an implementation on a OS. In Arduino they are non-blocking and return -1 when there's no characters available. The following patch fixes the behavior:

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

According to https://en.cppreference.com/w/cpp/types/enable_if it should be in the type_traits header file. But currently the lib doesn't mention enable_if at all.

The same goes for is_arithmetic (https://en.cppreference.com/w/cpp/types/is_arithmetic).

Hi,

I am trying to use this library to have a FIFO buffer for ISR's.
In the ISR I am calling the push() member function of a std::queue object like so:

struct STriggerRecord
{
   volatile int iSensorNumber;
   volatile int iSensorState;
   volatile unsigned long lTriggerTime;
};
std::queue<STriggerRecord> _STriggerQueue;
void RaceHandlerClass::TriggerSensor2()
{
   STriggerRecord S2Trigger;
   S2Trigger.lTriggerTime = micros();
   S2Trigger.iSensorNumber = 2;
   S2Trigger.iSensorState = digitalRead(_iS2Pin);;
   _STriggerQueue.push(S2Trigger);
}

However the last line of this code causes my arduino to freeze.
After I posted this question on arduino.stackexchange, I got a comment from someone who implies the freeze is caused by 'malloc() not being reentrant, and since the.push()` member function of a queue tries to allocate memory, it causes the freeze.

Is there any way around this? I really need a FIFO buffer for my ISR's, and wouldn't know how to achieve this other than using an std::queue container (or similar).

#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() {}

I was wondering what the status of this library is. I'd very much like to use this kind of stuff in my Arduino projects, especially the newer C++11 template stuff (so I was happy to find initializer_list was added). However, it seems that development is stalled / diverged a bit, so I'm wondering a few things. These questions are as much for @maniacbug, who I think initially created this library, as well as for @kibergus and @rpavlik, who have been making some significant changes in their forks AFAICS.

• Are there any plans to update to a newer upstream version? Seems this repo contains uClibc++ 0.2.2, while there has been a 0.2.4 release in 2012, and some more activity in the git repo (most recently two months ago).
• Are there any plans to submit changes back upstream? It seems there are some changes in this repository, and even more in the repositories of @kibergus and @rpavlik that could be useful for upstream uClibc++ as well, while at the same time reducing the maintenance burden for this Arduino port.
• Are there any plans to merge the ports of @kibergus and @rpavlik into this one, or vice versa? Having a single canonical "latest version", as well as a single place to focus development effort might help in moving forward?
