Hello, I've been working on a native fpa toolchain including gcc-2.95.3 and glibc-2.2.5, for a strongarm sa1110 which is detected as armv4l-unknown-linux-gnu. its currently running a vfp toolchain that can run both fpa and vfp binaries through floating point emulation. I also have an sdk for the os it runs that comes with a vfp cross compiler. (pdaxrom beta1) Im stuck now with trying to get glibc to compile as fpa rather than vfp, (for gcc-2.95.3 is default fpa)... the error is: include/libc-symbols.h -o /sources/glibc-build/math/setfpucw.o ./ccdjmC0e.s: Assembler messages: ./ccdjmC0e.s:22: Error: selected processor does not support `rfs r3' ./ccdjmC0e.s:38: Error: selected processor does not support `wfs r3' distcc[16729] ERROR: compile ../sysdeps/generic/setfpucw.c on 192.168.129.200 failed make[2]: *** [/sources/glibc-build/math/setfpucw.o] Error 1 make[2]: Leaving directory `/mnt/lfs/sources/glibc-2.2.5/math' make[1]: *** [math/subdir_lib] Error 2 make[1]: Leaving directory `/mnt/lfs/sources/glibc-2.2.5' make: *** [all] Error 2 When i supply --without-fp to the glibc compile it succeeds (under vfp toolchain) but i end up with: # objdump -p crtend.o crtend.o: file format elf32-littlearm private flags = 600: [APCS-32] [VFP float format] [software FP] When im looking for: # objdump -p crtend.o crtend.o: file format elf32-littlearm private flags = 0: [APCS-32] [FPA float format] ***: Does whether im compiling glibc under a vfp crosschain or a fpa crosschain(gcc) effect this outcome? ***: Are there some extra paramaters i can pass to glibc configure to work this through ? perhaps something relating to the cpu or float preferences ?, im really just looking for a way to make a gcc-2.95.3 compatible glibc... regards, and thankyou for your time, Hayden Thring.
