I am trying to compile for ARM Cortex M3, and get this error when building a Hello World program.
我正在尝试编译ARM皮质M3，在构建Hello World程序时得到这个错误。
Have tried to build using --specs=rdimon.specs, which allows the program to compile, but it is then "Killed" by the target platform.
尝试过使用——spec =rdimon。spec允许程序编译，但随后被目标平台“杀死”。

This error means that the standard functions are not defined. You can try to compile with the -ffreestanding option (see What is ffreestanding option in gcc?).
这个错误意味着没有定义标准函数。您可以尝试使用-ffreestanding选项进行编译(参见在gcc中什么是ffreestanding选项?)
