请教一个命令行下直接使用交叉工具链的编译问题(已解决)

onion2014

写了一个c的hello小应用来测试交叉工具链的编译效果
#include
int main()
{
int i;
i = 0;
printf("i=%d\n",i);
}
cw下的交叉工具链是CW MCU v10.5\Cross_Tools\arm-none-eabi-gcc-4_7_3\bin\arm-none-eabi-gcc.exe -o test test.c
编译失败了，厂商工具链是有什么限制吗？还是使用上有什么要求？
使用其他开源交叉工具链是没有问题的

请教fae，这个cw里的工具链不能单独编译程序文件吗？还是不支持标准c库

FSL-TICS-RICK

对于嵌入式的系统来说，因为Printf（）是与具体的硬件相关的。
所以，CW的编译工具中EWL的库中没有提供对Printf的支持。
建议楼主用IDE的编译方式，CW的IDE在新建工程是提供了一个Debuger console可以用来输出printf().
如果楼主坚持要用command的方式编译的话，建议参考cw自带的例子自己写printf()的相关代码。
例子在{cw}\MCU\CodeWarrior_Examples\Kinetis_Examples\
