c - 编译 ARM 演示项目时出现链接器错误

Question

我安装了 GNU ARM Embedded Toolchain gcc-arm-none-eabi

当我在https://github.com/ChibiOS/ChibiOS-RT的一个演示项目上运行 make 时

我收到此链接器错误

main.c: In function 'Thread1':
main.c:36:1: warning: no return statement in function returning non-void [-Wreturn-type]

Answer 1

GCC 4.8 不支持LTO和ggdb启用一起。只需禁用一个或另一个。

尝试配置您的 Makefile：

USE_LTO = no

或者

USE_OPT = -O2 -fomit-frame-pointer -falign-functions=16

没有 -ggdb 标志
