如何使用FMT库格式化指针

我正在接受一些人的建议，并查看FMT库：http://fmtlib.net

它似乎具有我需要的功能，并声称支持%p(指针(，但是在编译使用％P的代码时，我会收到一系列的模板错误(难以理解(。我将在此结束时发布它们。

如果我拔出%p和相应的指针参数，则在VS2017 C 17中进行编译。

但是，我对如何解码模板错误或获得有关为什么首先不接受 %p参数的洞察力感到茫然。

我尝试将论点施加到(void*)-同一问题。
我尝试使用格式 {}中的python样式语法 - 相同的问题。
我已经与其余格式分开分解了％p位 - 同一问题。

我看到对用户类型有支持 - 但是在这种情况下，我只想将其作为原始指针值输出。我可以跳过它，毕竟，指针地址真的有多有价值？但是，当然，这意味着从sprintf转换为fmt::format进行更多的工作，以追捕所有％p并"对它们做某事"，例如Elide。

但文档似乎表明得到％p的支持-http：//fmtlib.net/latest/latest/syntax.html(大约3/4 down -way down -down-搜索'pointer'或'pointer'或'p'(。<<<<<<<<<<<<<<<<(。/p>

这是调用函数：(注意：pAccels被声明为const ACCEL *(

    m_hAccel = ::CreateAcceleratorTable(const_cast<LPACCEL>(pAccels), (int)count);
    if (!m_hAccel)
    {
        auto error = GetLastError();
        throw CWinAPIErrorException(__FUNCTION__, "CreateAcceleratorTable", fmt::format("%p,%u", pAccels, count), error);
    }

这是诊断派：
