You need either --fpu=VFPv3+SoftVFP or -mfloat-abi=hard.
I still get the same error.
In that case, you'll have to be more specific (complete command
lines).
Well, the object files are compiled with:
armcc --wchar32 --library_interface=aeabi_clib -g --cpu=cortex-a9 -c
f1.c -o f1.o
(armcc is 4.0 build 650 if it matters)
and the link command is:
arm-2009q3-68-arm-none-eabi/bin/arm-none-eabi-gcc f1.o -o f.u
-Tgeneric-hosted.ld -mcpu=cortex-a9 -mfpu=vfp -mfloat-abi=hard
--fpu=VFPv3+SoftVFP
which leads to:
error: f1.o uses VFP register arguments, f.u does not
failed to merge target specific data of file f1.o
f1.c can be only a sample code:
===================================
int myfunc(int i) { return i+1;}
int main()
{
return myfunc(1);
}
===================================
Thanks,
Christophe.
