identifier "va_list" is undefined in Code Composer Project

Question

I am use TI 8.3.11 (Code Composer Studio) Device Family C6000, SYS/Bios 6.67.3.01

I have a problem with variadic function, which accepts a variable number of arguments. My class:

#include "stdint.h"
#include "stdarg.h"
#include <xdc/runtime/Error.h>
#include <xdc/runtime/System.h>
#include <xdc/runtime/Memory.h>
#include <ti/sysbios/heaps/HeapBuf.h>
#include "nexus.hpp"
class Neuron
{
public:
    explicit Neuron() = default;
    ~Neuron();
public:
    void AllocManyNexuses(int count, ...) noexcept;
}

And in cpp i determined it:

void Neuron::AllocManyNexuses(int count, ...) noexcept
{
    const xdc_runtime_IHeap_Handle nexusHandle=reinterpret_cast<xdc_runtime_IHeap_Handle>(heap4KbpNetNexus);
    Error_Block eb;
    Error_init(&eb);
    nexus =reinterpret_cast<Nexus*>(Memory_calloc(nexusHandle, sizeof(Nexus), 0, &eb));


    va_list doubleLists;
    va_start(doubleLists, count);    
    for(int i=0;i<count; ++i)
    {
    and etc
}

My compiler get me some dummy errors:

What I do wrong, guys?

Answer 1

#include <iostream>

template<class ...DOU>
static void product(DOU ...doubles) {
    constexpr int numOfArgs=sizeof...(doubles);
    double arr[numOfArgs]={};
    int index = 0;
    auto setValLamda=[&arr, &index](double i){
        arr[index]= i;
        ++index;
        return i;
    };
    auto supapro = { (setValLamda(doubles),...)};
    for (double val:arr)
    {
        std::cout << val << '\n';
    }
}



int main() {
    product<double>(2.2, 6.2);
    return 0;
}
