ASIO使用已删除的函数C++

帖子中提到的项目可以找到@https://github.com/Opendigitalradio/data-over-dab-example

在尝试运行一个旨在接收任意DAB+数据的旧项目时，我在构建该项目时遇到了一个问题。

/home/daan/data-over-dab-example/src/receiver.cpp: In function ‘int main(int, char**)’:
/home/daan/data-over-dab-example/src/receiver.cpp:123:65: error: use of deleted function ‘dab::ensemble::ensemble(dab::ensemble&&)’

几个星期以来，我一直在尝试修复这个错误，为了继续这个项目，我们不得不更改C++的源文件。正如你所看到的，错误提到

/usr/include/c++/9/atomic:73:5

在这个文件中，可以在第73行找到以下代码：

public:
atomic() noexcept = default;
~atomic() noexcept = default;
atomic(const atomic&) = delete;
atomic& operator=(const atomic&) = delete;
atomic& operator=(const atomic&) volatile = delete ;

当我删除最后三个= delete时，项目就会运行，其功能不会受到损害。尽管如此，我们现在使用的修复程序似乎不正确，我们想解决它，但我们不知道如何解决。

到目前为止，我们认为这可能是因为使用了较新的库，因为该项目已经有3年的历史了，但用不同版本重新安装几次也无济于事。

这个错误来源的代码可以在集合中找到。h:

struct ensemble
{  ensemble(symbol_queue_t & symbols, internal::types::transmission_mode const & mode); }

合奏.h可以在以下位置找到：https://github.com/Opendigitalradio/libdabdecode/blob/master/include/dab/ensemble/ensemble.h

我们正在最新版本的Ubuntu上运行这个项目。

我们一直在与该项目的开发人员联系，但他们在过去两年里没有看过，所以他们也没有任何线索。

如果有任何不清楚的地方，或者您需要更多的样品，我们很乐意提供。
