Nofpu means "no floating point unit" it concerns the way of computing=20 floats. Don't pay attention to that, we used this option since a while=20 without any problems. You should be able to turn of this option by modifying the makefile of the= =20 buildroot: SOFT_FLOAT:=3Dfalse The comment of the makefile concerning the option SOFT_FLOAT: # Soft floating point options. # Notes: # Builds for gcc 3.4.x. # Can build for gcc 3.3.x for mips, mipsel, powerpc, and arm (special) # by using custom specs files (currently for 3.3.4 only). # NOTE!!! The libfloat stuff is currently removed from uClibc. The # arm soft float for 3.3.x will require reenabling it. # (i386 support will be added back in at some point.) # Only tested with multilib enabled. # For i386, long double is the same as double (64 bits). While this # is unusual for x86, it seemed the best approach considering the # limitations in the gcc floating point emulation library. # For arm, soft float uses the usual libfloat routines.
