For some reason when I build a gcc cross for strongarm-elf using a cygwin host I don't get the soft floating point libraries. I don't get any errors while building, and the croos compiler works fine, just no soft-float libraries. Multilib appears to be working as I get be (-mbig-endian) and fpu (-mhard-float) directories populated with libraries. I thought the default library might be soft-float/little-endian but when I compile a c or c++ app and then try and link it I get an error telling me that the library was compiled for hardware FP. Can anyone help me - I've read everything and tried everything I can but just can't seem to get the expected results. I hope the following information will help. Tim I'm using the following distributions:- binutils-2.13 gcc-3.2 newlib-1.10.0 I configure using --target=strongarm-elf --prefix=/usr/local --enable-languages=c,c++ --with- newlib" The multilib options in src-dir/gcc/config/arm/t-strongarm-elf are MULTILIB_OPTIONS = mlittle-endian/mbig-endian mhard-float/msoft-float MULTILIB_DIRNAMES = le be fpu soft If I invoke the compiler with --print-multi-lib I don't see any soft-float libraries.... >$ strongarm-elf-gcc gcc --print-multi-lib .; be;@mbig-endian fpu;@mhard-float be/fpu;@mbig-endian@mhard-float The following output from genmultilib is as I'd have expected (from build-dir/gcc/multilib.h) static const char *const multilib_raw[] = { ". !mlittle-endian !mbig-endian !mhard-float !msoft-float;", "le mlittle-endian !mbig-endian !mhard-float !msoft-float;", "be !mlittle-endian mbig-endian !mhard-float !msoft-float;", "fpu !mlittle-endian !mbig-endian mhard-float !msoft-float;", "soft !mlittle-endian !mbig-endian !mhard-float msoft-float;", "le/fpu mlittle-endian !mbig-endian mhard-float !msoft-float;", "le/soft mlittle-endian !mbig-endian !mhard-float msoft-float;", "be/fpu !mlittle-endian mbig-endian mhard-float !msoft-float;", "be/soft !mlittle-endian mbig-endian !mhard-float msoft-float;", NULL }; static const char *const multilib_matches_raw[] = { "mbe mbig-endian;", "mle mlittle-endian;", "mlittle-endian mlittle-endian;", "mbig-endian mbig-endian;", "mhard-float mhard-float;", "msoft-float msoft-float;", NULL }; static const char *multilib_extra = ""; static const char *const multilib_exclusions_raw[] = { NULL }; ------ Want more information?
