Error: abort symbol missing

DS1 over 1 year ago

I get this error upon compiling : Error: L6218E: Undefined symbol abort (referred from abort_message.cpp.o).

This is the only error I get.

How can I define it in my code?

Tried #include <signal.h> to set the SIGABRT handler. But got an error: file not found!

How should I proceed?

You likely need to reimplement this (along with any other semihosting functions in your code). It could be as simple as: void __attribute__((noreturn)) abort(void){ while(1); }

I finally added this in .h file and it removed the linker error: extern "C" void __attribute__((noreturn)) abort(void) { while(1); }
