如何在 boost.process 间共享内存中使用复杂结构"push_back"函数向量

很抱歉打扰您。我正在编写代码以生成此代码，"http://coliru.stacked-crooked.com/a/0ab21481b69d87bb在这个问题"Boost共享内存中的结构和向量"中，的基础

但是，我陷入了这一行的编译错误。

data.push_back(id);   // 14 line in main function 

此"数据"val不是匹配的"push_back"函数。此val由此行中的"auto&"声明。

auto& data = Shared::locate(smt);   // 10 line in "while(1)" of main function

(这个定位(smt)函数是在共享内存中构造复杂结构的向量)

我假设"data"是复杂结构的向量或迭代器，但据我所知，并没有办法运行这一行。

我想知道我在这个代码的某个地方错了，但我不知道在哪里。

请帮帮我。

注意1："data.push_back(id)；"的行没有匹配的函数用于调用"boost:：container:：vector，boost:：interprocess:：iset_index>>，boost：：interprocess::allocater，boost::interprocess::iset_index>>>，boost：：interprocess:：segment_manager，boost：：interrocess:：iset_index>>：：：push_back(InData&)">候选者：void boost:：container:：vector:：push_back(const T&

注意2：现在，我试着换到下面的行；

cv::Mat_<cv::Vec3b> mat;
cv::VideoCapture vcap(0);
InData id(Shared::alloc<uchar_allocator>);
// camera open check
if (!vcap.isOpened())
return -1;

但是，另一个编译错误出现在"非类类型的'id'"中。我觉得缺少什么。我该怎么办？
