Which gcc did you use? > > (crosstool-0.28-rc37, gcc-3.4.3, glibc-2.3.3, binutils-2.15) Just as you say except I used gcc-3.4.2; crosstool-0.28-rc37 gcc-3.4.2 glibc-2.3.3 binutils-2.15 It shouldn't matter; but I'm using 2.6.8.1 linux headers instead of 2.4.21. No extra patches other than crosstool's patches... Hmm, that might be it; there is a nolibfloat patch in patches/gcc-3.4.2. If your using gcc-3.4.3 there is no corresponding patches directory. I think that means that no patches at all are being applied to gcc. Try it again with gcc-3.4.2... [time passes] Okay, I just confirmed it. One of the patches in /patches/gcc-3.4.2 is required to get it to compile, but I don't know which; left as an exercise to the reader. :-) (I tried the nolibfloat patch on it's own, but that's not it.)
