Linker error when compiling ARM demo project

Question

I installed the GNU ARM Embedded Toolchain gcc-arm-none-eabi

When I run make on one of the demo projects from https://github.com/ChibiOS/ChibiOS-RT

I get this linker error

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

main.c: In function 'Thread2':
main.c:53:1: warning: no return statement in function returning non-void [-Wreturn-type]

Answer 1

GCC 4.8 does not support LTO and ggdb enabled together. Just disable one or another.

Try to configure your Makefile:

USE_LTO = no

or

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

without -ggdb flag
