Re: possible error for cross-gcc-2.3.5-glibc-2.3.2?

I can't reproduce this using gcc-3.3-20041006. I guess I'll try prerelease-3.3.5-20040914 now, is that what you used?

Are you using any patches?

Also have been able to compile the linux-2.6.8.1
kernel for the samsung s3c2410 - smdk2410 board
without getting any errors. Though have yet to see if
it works.

Great...


A question here - the s3c2410 does not have a FPU.
Thus do i have to enable support for software FP ops for glibc? i though anyway the kernel took care of
that with its FP emulation ?

The kernel FP emulation is supposed to, but it's pretty slow, and people who want fast floating point often turn on one of the soft floating point options. You should stick with kernel FP emulation if it works well for you. - Dan
