BINUTILS_DIR=binutils-2.16.1

4) Ran 'sh ./demo-mipsel.sh'


It ran for about an hour, then I got:


/home/dkarlton/crosstool-0.38/build/mipsel-unknown-linux-gnu/gcc-3.3.4-glibc
-2.3.2/gcc-3.3.4/gcc/libgcc2.c

  Known bug in 3.3 series vs MIPS.  You either need a more recent gcc or to
backport the fix at

http://gcc.gnu.org/ml/gcc-patches/2004-06/msg01187.html

(Found from

http://www.google.co.uk/search?q=%22operation+combines+symbols+in+different+
segments%22+mipsel&sourceid=mozilla-search&start=0&start=0&ie=utf-8&oe=utf-8
&client=firefox-a&rls=org.mozilla:en-GB:official

then following the thread starting at

http://sources.redhat.com/ml/binutils/2005-02/msg00644.html

and considering the possible gas-patch at

http://sources.redhat.com/ml/binutils/2005-02/msg00648.html

but it seems better to fix gcc by following Richard Sandiford's advice at

http://sources.redhat.com/ml/binutils/2005-02/msg00702.html

which points to the thread at

http://gcc.gnu.org/ml/gcc-patches/2004-06/msg00970.html

which eventually ends up there. Phew!)



    cheers,

I was able to build, but alas, anything I compile is still 70k...
