Has anybody built a workable cross GCC setup for ARM recently? Mine
got broken, and when I built a new one, I started getting errors:
/usr/local/packages/crossdev/lib/gcc/arm-generic-elf/4.0.3/../../../../arm-generic-elf/bin/ld: ERROR: ../../ports/Olimex-LPC-P2148/dex1.o uses software FP, whereas demo uses hardware FP
/usr/local/packages/crossdev/lib/gcc/arm-generic-elf/4.0.3/../../../../arm-generic-elf/bin/ld: failed to merge target specific data of file ../../ports/Olimex-LPC-P2148/dex1.o
(repeated for all the files in my executable.) I did everything I
could think of to turn off hardware FP, and none of the files use FP
anyway. I think the "failed to merge" might have something to do with
big-endian/little-endian, but I haven't done anything special there.
My microcontroller is little-endian.
I've tried gcc-4.0.3, 4.1.1 and 4.2.1 with and without the RTEMS
patches. There used to be a useful resource at www.objsw.com, but
that site has fallen off the net.
Any help/suggestions?
Thanks,
d.
