As far > as I can see, m68k-linux isn't a multilib target. Problem occurs mainly due to restricted addressing modes in v4e. For ex v4e supports only 16-bit displacements. So all crt* files needs to be build for v4e. Also v4e does not have extended floating point instructions (XF mode) so we may have to modify t-* for fpgnulib.c. > -- > // Bernardo Innocenti - Develer S.r.l., R&D dept. > \X/ http://www.develer.com/ > > __________________________________________________ Do You Yahoo!?
