我正在寻找在 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

意味着不存在 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,
             from /opt/arm-2010.09/bin/../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/include/c++/4.5.1/bits/basic_ios.h:39,
             from /opt/arm-2010.09/bin/../lib/gcc/arm-none-eabi/4.5.1/../../../../arm-none-eabi/include/c++/4.5.1/ios:45,

...

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？

提前谢谢了！

vector, list，他们基本上都属于Standard template library。对于生态系统，可能也有类似的东西可用BOOST。我想你可以检查这个链接

你需要ustl. 请参阅在 eCos 应用程序中使用 uSTL。

这是一个使用vector.

您必须包括

#include <ustl.h>

然后你可以像这样实例化一个向量：

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