Re: Undefined reference to longjmp/setjmp

[David S. Alessio]

Hello, Foti, I wrote setjmp/longjmp for armv7-m some time ago.  The code should be in file: arch/arm/src/armv7-m/gnu/up_setjmp.S If not, it’s attached here. Cheers, -david

I am getting undefined references to longjmp/setjmp. I am using an STM32F4 and GCC: arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599] As I see, this combination of arch and compiler should work for setjmp/longjmp, so I believe that something is misconfigured on my side. Is there any special Kconfig option that I am not aware of? Do I need any special compiler flags?
