There is also a configuration option that must be set to use the setjmp
in NuttX. It is in the top-level Kconfig as I recall.
You don't get a compilation error so you are probably including the
toolchain's setjmp.h. So most likely you have -nostdlib or something
like that on the command line so that you do not bring in the
toolchain's C library version of setjmp/longjmp.

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,

Hi everyone!
I just started adding Lua to my NuttX-based project, but I have some
problems with it.
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?
