Methinks glibc should be used, NOT newlib since the target is i486-pc-linux-gnu. On the other hand, a cross compiler from i686-pc-linux-gnu to i486-pc-linux-gnu makes no sense whatsoever [well, I can think of a situation where it might make sense but I doubt that's the case here.] Also, reformatting disks and reinstalling redhat 6.1 is rather unnecessary. Is the following _really_ correct? > > host=i686-pc-linux-gnu > > target=i486-pc-linux-gnu An earlier message said the target was i386-elf (or i486-elf). Note that while linux uses the ELF file format, i386-elf is NOT the same as i386-linux. Mike/Richard (how come messages are from mike@... and yet the email is signed richard@... ?), what are you _really_ trying to build?
