Hey,
some more information for you in the hope that it will help you to
find the cause for these problems. I attached the Makefile from the
gcc-cross-4.5 build, libgcc-subdirectory, and the Makefile from the
gcc-cross-sdk-4.5, libgcc subdirectory. As you can see in line 67
where CC is set, the former Makefile includes the correct
TARGET_CC_ARCH (-mtune=armv7-a etc.), while the latter doesn't contain
this and especially doesn't contain the -mfloat-abi=hard which would
be required to perform the correct hard float compilation. I guess
there is something missing in the call to ./configure for the
gcc-cross-sdk-build, perhaps you could point me to the directive that
has to be added to have the correct CFLAGS for building libgcc.
Thanks,
Julian
