c++ - 在 g++ 中编译 Windows C++ 程序

Question

我正在尝试用 g++ 编译一个 Windows C++ 程序。这就是我得到的。

/usr/include/c++/4.4/backward/backward_warning.h:28:2: warning: #warning This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date. Please use a non-deprecated interface with equivalent functionality instead. For a listing of replacement headers and interfaces, consult the file backward_warning.h. To disable this warning use -Wno-deprecated.

我首先注意到的是这些变量类型称为 _TCHAR、_int64 和 LARGE_INTEGER，这可能是 Windows 的东西。可以将它们更改为什么以便它们可以在 g++ 中工作？

此外，如果您知道此处还有其他任何内容可以转换为 g++，那将很有帮助。

我从这里得到代码: http://touc.org/btree.html

来自链接页面:

  // the main function is just some code to test the b-tree.  it inserts 100,000 elements,
  // then searches for each of them, then deletes them in reverse order (also tested in
  // forward order) and searches for all 100,000 elements after each deletion to ensure that
  // all remaining elements remain accessible.

如果你完全放弃 _tmain，你应该可以开始了。 __int64 和 LARGE_INTEGER 仅用于调用 QueryPerformanceCounter，并且只能从测试主函数调用。看起来代码在其他方面是相对可移植的 C++，而且实际上看起来错误只是真正从 _tmain 开始。
