在ARM上为eCos构建C++应用程序

Question

我希望在ARM处理器上为eCos构建一个C++应用程序。我的程序需要几个标准的C++头文件，如向量，流，列表，...

我的问题是:我如何才能做到这一点？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，我得到以下错误

fatal error: vector: No such file or directory

这意味着C++向量库不存在。

但是，arm-none eabi-g++编译器确实包含了这些标准的头文件。我得到了以下关于‘’的错误：

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,

...

我可以使用eCos的arm-none-eabi-g++编译器吗？如果是，我如何解决这些错误？如果没有，我应该怎么做？

首先要感谢大家！

Answer 1

vector, list，它们基本上属于Standard template library。对于ecos，可能会有类似的东西可用，同样也是BOOST。我想你可以查看this link

Answer 2

你需要ustl。参见Using uSTL in eCos applications。

这里有一个使用vector的简短示例。

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);
