Eric, All,

Which looks pretty obvious: hard-float are not possible for VFP.
Although
this is theorically possible, gcc-4.4 (and all other versions, AFAIK)
do
not support building hard-float for VFP.

What am I doing wrong?



Build with soft-float.



I ran into this problem as well. There ought to be a configuration option which selects the ARM processor version and passes the correct options to gcc configure so that the default options do create a broken tool chain.


Sorry, I'm late to this thread.  GCC 4.5 and later support the hard
float ABI on the Cortex-As with VFPv3.  I think 4.4 does as well.
What was the problem?


He's building 4.4.6.


I saw the scripts/addToolVersion.sh script and added gcc-4.6.3.
But when I run "ct-ng menuconfig" this is not an option for GCC.
How do I make this show up in menuconfig?

You need CT_EXPERIMENTAL=y

I ran "CT_EXPERIMENTAL=y ct-ng menuconfig" but I don't see gcc-4.6.3.
