there should be no problems with gcc-3.4.6 and any architecture on the uClibc side of things. there is someone on bugs.uclibc.org who has spent a lot of time getting nios2 things working in uClibc again. > -rw-r--r-- 1 rpjday rpjday 5544 2006-05-07 09:57 elf2flt.ld ah elf2flt, how i stab thee ... this will require custom modifications to your binutils install step > is this a sane way to start the process -- just to see where the > older toolchain has problems building the current version of uclibc, > and seeing if there's an obvious fix? thanks. i'm pretty sure svn trunk of uClibc actually has a decent nios2 status. it'd prob be faster to go the other way -- enable everything you expect and only turn off upon failure. -mike
