[uClibc] hardware FP, software FP

[Peter Källström]

Hi,

I'm trying to compile the uClibc-toolchain with gcc 3.3.1 and uClibc 0.9.22. The problem I run into is following:

/home/samba/uClibc-toolchain/toolchain_arm/arm-linux/bin/ld: ERROR: /home/samba/uClibc-toolchain/build_arm/gcc-final/gcc/crtendS.o uses hardware FP, whereas libgcc_s.so.0.9.9 uses software FP
File format not recognized: failed to merge target specific data of file /home/samba/uClibc-toolchain/build_arm/gcc-final/gcc/crtendS.o
/home/samba/uClibc-toolchain/toolchain_arm/arm-linux/bin/ld: ERROR: /home/samba/uClibc-toolchain/toolchain_arm/arm-linux/lib/crtn.o uses hardware FP, whereas libgcc_s.so.0.9.9 uses software FP
File format not recognized: failed to merge target specific data of file /home/samba/uClibc-toolchain/toolchain_arm/arm-linux/lib/crtn.o
collect2: ld returned 1 exit status
make[3]: *** [libgcc_s.so] Error 1

I searched for this error and found a post from this list: http://www.uclibc.org/lists/uclibc/2003-February/005593.html
However, even if I add --nfp --without-fp to EXTRA_GCC_CONFIG_OPTIONS, I still get the same error.

Does anyone know a solution to this?
