Question

我正在尝试用g ++编译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.

我注意到的第一件事就是有一些名为_TCHAR，_int64和LARGE_INTEGER的变量类型，它们可能是Windows的东西。这些可以改变什么，以便它们可以用g ++工作？

另外，如果你知道的其他内容可以转换为g ++，那将会有所帮助。

我从这里得到了代码： http://touc.org/btree.html

Answer 1

最简单的答案可能是针对winelib构建它。

最好的解决方案，虽然做了很多工作，但是将#ifdef WIN32块放在所有特定于Windows的东西周围，同样#ifdef LINUX围绕相同功能的linux实现。这可能需要大量的重组和重构。

Answer 2

从链接页面：

  // 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，那么你应该最好去。仅使用__int64和LARGE_INTEGER以便可以调用QueryPerformanceCounter，并且仅从测试主函数调用{{1}}。看起来代码是相对可移植的C ++，事实上看起来错误只是真正从_tmain开始。

Answer 3

如果您正在使用_TCHAR，那么您还在代码中使用其他特定于Windows的库。我已经可以看到QueryPerformanceCounter和QueryPerformanceFrequency（我曾经使用的前两个Windows库方法，实际上。=]。）更改类型不会让你在Windows库之外找到匹配功能的下一个阶段。很明显，你的源文件已经超过了一千行，但是你有一个你可以发布的移植代码片段，或者你是否正在尝试做一个大型项目？

Answer 4

我可能错了，但您不必包含windows.h来构建btree或类似的东西。查找与平台无关的代码，或者只是将所有这些特定于平台的调用删除为QueryPerformanceCounter等等......

或者只是获得另一个好的基于模板的B（或B +）树实现。有很多，如果你愿意，我可以分享我的。
