【问题描述】：

我希望在 ARM 处理器上为 eCos 构建 C++ 应用程序。我的程序需要几个标准的 C++ 头文件，例如 vector、iostream、list、...

我的问题是：我怎样才能做到这一点？有没有人有为 eCos 构建和部署 C++ 应用程序的经验？

当我使用 arm-eabi-g++ 编译器编译应用程序时，出现以下错误

fatal error: vector: No such file or directory

表示不存在 C++ 向量库。

但是，arm-none-eabi-g++ 编译器确实包含这些标准头文件。我确实收到以下错误：

In file included from /opt/arm-2010.09/bin/../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/include/c++/4.5.1/bits/locale_facets.h:43:0,

...

我可以为 eCos 使用 arm-none-eabi-g++ 编译器吗？如果是，我该如何解决这些错误？如果没有，我该怎么办？

非常感谢！

【解决方案1】：

vector, list，基本上都属于Standard template library。对于生态系统，BOOST 也可能有类似的东西可用。我想你可以查看this link

【解决方案2】：

您需要ustl。见Using uSTL in eCos applications。

这是一个使用vector的简短示例。

你必须包括

#include <ustl.h>

然后你可以像这样实例化一个向量：

ustl::vector<int> v(2);
