std::thread includes don't get resolved correctly on Windows

[Dlougach]

The <thread> header supplied with caide only actually defines anything when #if defined(_GLIBCXX_HAS_GTHREADS) condition is satisfied. This makes it impossible to inline any code that depends on std::thread.

Hi,

Can you share your caide.ini as well as the error that you're getting?

Example code:

#include <algorithm>
#include <iomanip>
#include <istream>
#include <map>
#include <numeric>
#include <ostream>
#include <set>
#include <sstream>
#include <string>
#include <utility>
#include <vector>
#include <thread>
using namespace std;
// Powered by caide (code generator, tester, and library code inliner)


class Solution {
public:
    void solve(std::istream& in, std::ostream& out) {
    }
};

void solve(std::istream& in, std::ostream& out)
{
    std::thread a = std::thread([]() {});
    out << std::setprecision(12);
    Solution solution;
    solution.solve(in, out);
}

the config is default for the VS extension:

Seems to be fixed in a recent libstdc++. Until I upgrade it, you can get it manually e.g. here: download and unpack the deb file, find c++ directory and copy it to D:\Contests\Caide\include\c++
