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?
