v1.3.0 problems

[Eronen, Jussi (GE Healthcare)]

Yann,
All,

soft-float doesn't seem to be an option here. Our target cpu has a fpu so definitely I wan't fp:hw enabled.
Using the option you suggested prevents glibc from compiling (some header file is not found).
Anyway, it seems that this patch is removed from gcc-4.3.x, so I stick with solution I have.

Your patch fixed the tuple problem and now toolchain builds without errors.

Thnx,
Jussi

Did you tell crosstool-NG to build a soft-float toolchain?
This is in "Target options" ---> "Floating point:" --> "software"

Yes. Painful, isn't it? :-)

This was wrong in the begining.

Not far. :-) The correct fix is attached. Could you give it a try, please?

BTW, I am collecting fixes both in the 1.3 branch in the repository, but also as a set of patches in the crosstool-Ng download directory.
