错误IAR编译器＆QUOT;＃包括＆QUOT; preprocessor指挥＆QUOT;的typedef＆QUOT;命令 [英] error in IAR compiler for "#include" preprocessor command and "typedef" command

问题描述

我刚开始与IAR编译器和ARM微控制器的工作。在第一步中，我想用做一个RSA加密我的 AT91SAM7S 的MCU（我知道这是不是一个很好的第一步;！）。）

I'm just started to work with IAR compiler and ARM microControllers. In the first step I want to do an RSA encryption using my AT91SAM7S MCU (I know that this is not a good first step! ;) ).

总之，谷歌搜索后，我发现包含两个文件，​​这网站名为 rsa.h 和 rsa.c 实现RSA算法的嵌入式设备。

Anyway, after Googling I found this site containing two files named rsa.h and rsa.c that implement RSA algorithm for Embedded devices.

于是我下载这个文件，并把它们放在我的程序的目录，（在同一目录中的的main.c 是）。

So I download this files and put them in the directory of my program, (In the same directory that main.c is).

现在，当我试图建立和编译这个项目，我遇到以下错误：

Now, when I trying to build and compile this project, I face the following errors :

大厦的配置：4rsa - 调试

看来我必须下载并添加一些库到我的计划，但我没有哪些库，我需要和我在哪里可以下载他们的任何想法。

It seems that I must download and add some libraries to my program, but I don't have any idea which libraries I am need and where I can download them.

FYI：

这是内容 rsa.h ：

我该如何处理这些错误？

How can I handle these errors?

请帮我开始使用此设备。
先谢谢了。

Please help me to getting started with this device. Thanks in advance.

推荐答案

rsa.h 编写不当。它需要包括 stdint.h 。这是不相关的IAR，ARM或其他任何东西。

rsa.h is incorrectly written. It needs to include stdint.h. This is not related to IAR, ARM or anything else.
