交叉编译错误“的手臂
我有一个关于交叉编译的问题。
#include <stdio.h>
int main()
{
printf("hellon");
return 0;
}
这是我用过的一个简单的hello世界代码。
我使用arm-none-eabi-g ++，从指导图形下载。 这是错误。 我不知道错过了什么。

这是编译器版本。

你下载了错误的工具链。
arm-linux-gnueabi-g++是使用arm-none-eabi ，它用于裸机程序。 这不包含libc，即标准库（glibc或eglibc）不在此工具链中。
因此，您需要下载arm-none-linux-gnueabi工具链（即arm-2013.05-24-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 ，而不是arm-2013.11-24-arm-none-eabi-i686-pc-linux-gnu.tar.bz2 ）。
要验证上述内容，请键入：
cd /home/kang/Utils/arm-2013.05/arm-none-eabi
在这里你会发现只有bin include lib share ，并且没有libc目录。
下载arm-2013.05-24-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 ; 在这里你会找到一个文件夹arm-2013.05/arm-none-linux-gnueabi/libc 。
您也可以通过编写来验证：
arm-linux-eabi-g++ -print-sysroot and
arm-none-linux-gnueabi-g++ -print-sysroot
另请参阅前面的问题：如何在交叉编译时使用外部库？
我正在使用arm-linux-gnueabi-g ++。 它下载了指导图形。
这是错误的。 你所有的输出都表明Mentor Graphics已经打包了一个arm-none-gnueabi工具链，并错误地命名为arm-linux-gnueabi （它甚至不适合命名约定）。
对不起，我打错了我的编译器。 我使用arm-none-eabi-g ++
获取arm-none-linux-gnueabi工具链（即定位GNU / Linux而不是EABI）的版本。
这个包含与Linux操作系统连接的GCC运行时。 你现在缺少的所有功能都是该界面的一部分。
