I've been doing this with my Firmware Linux build thingy for some time, so there's obviously more to it than that... > > How do I reproduce this again? > > My setup is: > - linux-2.6.21.5's "make ARCH=i586 headers_install" > - uClibc configured for arm You install i586 headers and then build an arm uClibc against that? How is that supposed to work at _all_? Your linux/asm directory would be all wrong. > - no locale support in uClibc > - uClibc-0.9.29's "make headers" > At this point, binutils' and gcc's flavour don't matter, if I'm not misled. ARCH=i586 plus uClibc's arch of arm: it go boing. ARCH=arm and uClibc's arch of arm, that might work. If that was a typo, then disabling locale support is the only potential point of weirdness, except that my config hasn't got locale support in it either. > I just tested this x-compiler: > - build/host: x86_64 (AMD) > - target: armv5b (xscale) I've built for armv4l and armv5l. Haven't done the big endian ones yet, but I've done both endiannesses of mips and they worked. > You'll see something like: > [ALL ] # > [ALL ] # configuration written to .config > [ALL ] # > [ALL ] ./extra/scripts/conf-header.sh .config > > include/bits/uClibc_config.h [ERROR] cc1: error: unrecognized command line > option "-mbig-endian" [ERROR] :0: error: bad value (armv5te) for -march= > switch In mine it's: Compile all sources at once into an object (DOMULTI) [N/y/?] n Manuel's hidden warnings (UCLIBC_MJN3_ONLY) [N/y/?] n # # configuration written to .config # ./extra/scripts/conf-header.sh .config > include/bits/uClibc_config.h CC ldso/ldso/ldso.oS AS ldso/ldso/arm/resolve.oS That's building for armv4l with 0.9.29 stock.

They're not doing it for me now. I'd like to reproduce the problem before endorsing a solution. > Regards, > Yann E. MORIN.
