Unable to start debug session

[ViggoAvatar]

Hello all, I'm having issues with starting a debug session on the STM8S003F3

Output from the debug terminal:
Compiling .pio/build/stm8s003f3/FrameworkArduino/weak_atexit.c.rel

This is after trying on linux, the same issue arose on winows without the segfault.

platform.ini is basic:
[env:stm8s003f3]
platform = ststm8
board = stm8s003f3
framework = arduino

and application even more so (main.c):
#include <Arduino.h>

void setup() {
// put your setup code here, to run once:
pinMode(PA1, OUTPUT);
}

void loop() {
// put your main code here, to run repeatedly:
digitalWrite(PA1, 1);
delay(100);
digitalWrite(PA1, 0);
delay(100);
}

any help would be much appreciated

To get STM8 debugging via STLink to work under Ubuntu 22.04, I had to perform the below 2 steps:

1. install missing libpython2.7.so.1.0 --> sudo apt-get install libpython2.7
2. create symbolic link for libmpfr.so.4 --> sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4

I found the hints here and here. Good luck!

Same issue here, but its not related to starting a debug seesion, but to compile in debug mode.
To actual start stm8-gdb above two actions are required unless stm8-gdb won't start, but the coredump is when "--debug" is issued. I am currently not sure if this is related to sduino lib / sdcc or some memory issues. I can compile WInterrupts.c manually without --debug. but with debug the core dumps.
