Oh, so it looks like I hit a bit of a wall there :-) I’ll take a look thanks. That bug talks about R_ARM_THM_CALL which I assume are thumb related.

Hi, the errors I get do not seen to mention R_ARM_THM_MOVW_ABS_NC. The errors are “relocation R_ARM_CALL out of range”. Today I recompiled everything from scratch with -fPIC to make sure I had no library compiled without it and I still get the same errors. Sorry, I could not find any trivial code that has the same issue yet. Following is the output of the compilation process: yawmoo at yawmoo-MRN...

Yes... it is "a thing". :) ARM has two modes: BE32 and

The R_ARM_JUMP24 relocation on ARM has specific semantics to implement ARM/Thumb interworking; see http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044e/IHI0044E_aaelf.pdf Note that R_ARM_CALL has the same operation but different semantics. I suppose that we could try looking at the addend to decide which relocation to use, but this would mean adding more complexity to the assembler (along with any pattern matching that would need to be done). It seems simpler, both conceptually and in...
