Question

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，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 ++矢量库。

但是，arm-none-eabi-g ++编译器确实包含这些标准头文件。我确实为''获得了以下错误：

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？如果不是，我该怎么办？

非常感谢提前！

Answer 1

vector, list，它们基本上属于Standard template library。对于ecos，类似的可能类似BOOST。我想你可以查看this link

Answer 2

您需要ustl。请参阅Using uSTL in eCos applications。

以下是使用vector的简短示例。

您必须包含

#include <ustl.h>

然后你可以像这样实例化一个矢量：

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

在ARM上构建用于eCos的C ++应用程序
