I am trying to build gcc for ARM. I am building GCC with the following
command:

CROSS_COMPILE=arm-linux- ../../src/gcc-3.3.2/configure
--prefix=/home/blasig/omap/tools/ --target=arm-linux --with-cpu=arm9tdmi
--without-fp -nfp --disable-fp --enable-languages=c --with-newlib
--without-headers --disable-shared --disable-threads; make all-gcc

However I am running into a problem that when I try to build a program I
get the following error:

arm-linux-ld: ERROR:
/home/blasig/omap/tools/bin/../lib/gcc-lib/arm-linux/3.3.2/libgcc.a(_udivsi3.o) uses hardware FP, whereas u-boot uses software FP
File in wrong format: failed to merge target specific data of file
/home/blasig/omap/tools/bin/../lib/gcc-lib/arm-linux/3.3.2/libgcc.a(_udivsi3.o)

Is this error a result of me not including an option for GCC so it
compiles a software floating point libgcc.a? If so, how does one
accomplish this? Or is it an error related to something else?

Thanks for your time

Upon further investigation the culprit seems to be the -msoft-float
flags. Whenever I compile code with that flag enabled and link it
against libgcc.a I get errors. How can I compile gcc (including libgcc)
so I can link against programs that are compiled with -msoft-float flag?
Or perhaps there is a more appropriate list to be asking this too?

Thanks,
Matthew
