关于使用arm-none-eabi-gcc的编译问题

发布于 2019-12-31 11:14:00 浏览：2772 订阅该版

我想移植rt-thread nano至我的工程内，工程使用的模板是一个Makefile工程.交叉编译器的版本是:
gcc version 8.2.1 20181213 (release) [gcc-8-branch revision 267074] (GNU MCU Eclipse ARM Embedded GCC, 64-bit)

在编译divsi3.S的时候出现编译错误，请问各路大神有没有经验能帮助我解决此问题。以下是编译信息

请问是不是我需要使用更低版本的编译器去重新尝试编译？
