Global variable referenced in section '.text' of main.o defined in discarded section '.bss'

In my main.c, I have int cursor = 0;.

This is later used in a function, where I use cursor += 1.

When I compile / link, I get an error:

cursor' referenced in section .text' of main.o: defined in discarded section .bss' of main.o

I'm relatively new to using GCC. I used to use MSVC previously, but I never got an error like this. Is there something I need to add into the linker script so it does not discard the BSS section?

Thanks

I'm not sure if it will help. You could try:

static int cursor = 0;

another thing you could try is, put:

int cursor;

as the global and then in main() put cursor=0; maybe it doesn't like initializing the global?

BSS is for uninitialized globals. So for some reason I think it's not initializing your cursor variable. So moving the initialization into the main() routine might fix it.
