> Hi,
> i'm trying to build an emdedded distro for arm machine following the instruction 
> inside 'Cross-Compiled Linux From Scratch - Embedded Version SVN-0.0.1-20081203-arm'
> At the moment i'm not able to build uClibc-0.9.30-rc3 like explained on chapter 
> '6.8. uClibc-0.9.30-rc3'.
>
> When i type 'make CC="${CLFS_TARGET}-gcc ${BUILD}"'
> i receive this error message:
> clfs:/mnt/clfs/sources/uClibc-0.9.30-rc3$ make CC="${CLFS_TARGET}-gcc ${BUILD}"
>   CC ldso/ldso/ldso.oS
> cc1: error: unrecognized command line option "-m32"
> make: *** [ldso/ldso/ldso.oS] Error 1
>
> My host pc is a 32 bit centrino 1.7Mhz machine running a fedora 9 os, so following instruction 
> in chapter '6.3. ABI Variables',i set BUILD=-m32.
> The above error message imply the cross gcc compiler build at '6.7. Cross GCC-4.3.2 - Static' 
> don't recognize the -m32 option.
> If i compile without setting BUILD enviroment variable i have the  log below.
> Any suggestion or workaround to procede?
> Thanks in advance
