I would guess that you have mixed versions somewhere, since the combined divmod instruction was removed from mspgcc in December in a flurry of activity that included http://mspgcc.git.sourceforge.net/git/gitweb.cgi?p=mspgcc/gcc;a=commit;h=e6f2470df0df37d3c745f904c4cd4ab39bee6713 My builds of 20120412 do not reference that function in vuprintf; the separated functions are invoked instead: llc[398]$ nm vuprintf.o U __udivdi3 U __udivhi3 U __udivsi3 U __umoddi3 U __umodhi3 U __umodsi3 Possibly you used the old compiler when you built msp430-libc. I don't know if that's an issue in the instructions you reference below (I don't maintain or even vet those). > this symbol can be found in gcc-4.4.5/gcc/config/msp430/libgcc.S in the old > mspgcc4 source that i built some time ago, but not any more in the new > version based on 4.6.3, although the symbol appears in many object files of > the msp430-libc > > btw, i followed these directions to build the tool chain > http://sourceforge.net/apps/mediawiki/mspgcc/index.php?title=Install:fromsource > > the same problem was reported in this mail on the list > From: Aljaž Srebrnič <a2pirates...@gmail.com> > Subject: [Mspgcc-users] Portfiles completed > Date: 6 jan 2012 11:12:54 HNEC Interesting; I missed that. The issue there also appears to be in part a reference to the wrong msp430-libc installation.
