Long longs with Yagarto

marks Guest #1965057 
Hi,

I am trying to use 64 bit maths on the STM32 compiled with Yagarto but 
get the link errors "undefined reference to `__exidx_start'" and 
"undefined reference to `__exidx_end'".

I am using the linker script written by Martin Thomas for the 'small 
digital picture frame' project (a great starting point!), adding in a 
section like:

__exidx_start = .;
.ARM.exidx   : { *(.ARM.exidx* .gnu.linkonce.armexidx.*) }
__exidx_end = .;

does not link.

Has anyone any pointers as to how to proceed?

Thanks

Hi,
I have solved this - there was a modified linker file in a later version 
of the 'Small Digital Picture Frame' on Martin Thomas' website that 
includes a exidx section. Long longs now compile and link!
