Hello All, I am new to this list. I am trying to build toolchain to support hard float based on sample: arm-cortex_a8-linux-gnueabi/crosstool.config Here is my recipe: binutils-2.20 cloog-ppl-0.15.9 gdb-6.8 glibc-2.9 glibc-ports-2.9 gmp-4.3.2 linux-2.6.32.25 mpfr-2.4.2 ncurses-5.7 ppl-0.10.2 gcc-4.5.1 mpc-0.8.1 CT_ARCH_ARCH="armv7-a" CT_ARCH_CPU="cortex-a8" CT_ARCH_TUNE="cortex-a8" CT_ARCH_FPU="vfpv3-d16" CT_ARCH_FLOAT_HW=y The toolchain was built successfully. But I found error as follow: ruckuus@markonah:~/tulcein/testbed$ ~/srikutil-glibc-hardfloat/arm-cortex_a8-linux-gnueabi/bin/arm-cortex_a8-linux-gnueabi-gcc -c test.c -mfloat-abi=hard ruckuus@markonah:~/tulcein/testbed$ ~/srikutil-glibc-hardfloat/arm-cortex_a8-linux-gnueabi/bin/arm-cortex_a8-linux-gnueabi-gcc test.o -o test -mfloat-abi=hard --verbose /home/ruckuus/srikutil-glibc-hardfloat/arm-cortex_a8-linux-gnueabi/lib/gcc/arm-cortex_a8-linux-gnueabi/4.5.1/../../../../arm-cortex_a8-linux-gnueabi/bin/ld: error: test.o uses VFP register arguments, test does not /home/ruckuus/srikutil-glibc-hardfloat/arm-cortex_a8-linux-gnueabi/lib/gcc/arm-cortex_a8-linux-gnueabi/4.5.1/../../../../arm-cortex_a8-linux-gnueabi/bin/ld: failed to merge target specific data of file test.o collect2: ld returned 1 exit status Is there anything wrong in the build process? Should I set : CT_TARGET_CFLAGS="" CT_TARGET_LDFLAGS="" CT_LIBC_GLIBC_EXTRA_CFLAGS="" ?? I really appreciate any response.
