Well on coldfire I can only get busybox 0.16.0 working with the latest git master tree of uclibc (latest uclibc release doesn't have working signals for m68k that busybox now requires). > I see in the latest version of uClinux for Blackfin that they have the > latest busybox.

You probably need to get a fairly up to date kernel, gcc, binutils, elf2flt, uclibc and busybox. I use gcc 4.3.3, binutils 2.19.1, uclibc git checkout from 2010/02/16, busybox 0.16.0 and linux 2.6.29 on the coldfire. Works great so far. I do not use the uclinux distribution at all, I do everything from scratch with each source package. > Should it be possible to take the Blackfin uClinux and set it up for ARM?

Not sure how well blackfind tracks the main trees of things (although I get the impression they follow it quite well), so it might work. Certainly I got a working elf2flt by going to blackfin. No other version worked at the time I started using the coldfire last year. I think mine is a checkout from april 2009 from blackfin. > Thanks, > Gary Altenberg > > > SPLIT include/autoconf.h -> include/config/* > GEN include/bbconfigopts.h > HOSTCC applets/usage > applets/usage.c: In function âmainâ: > applets/usage.c:32: warning: ignoring return value of âwriteâ, declared with > attribute warn_unused_result > GEN include/usage_compressed.h > 43+0 records in > 43+0 records out > 86 bytes (86 B) copied, 0.000170757 s, 504 kB/s > HOSTCC applets/applet_tables > GEN include/applet_tables.h > CC applets/applets.o > arm-elf-gcc: unrecognized option `-static-libgcc' Looks like a much newer gcc is needed to make busybox happy. > In file included from > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/netinet/in > .h:212, > from > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/arpa/inet. > h:23, > from include/platform.h:194, > from include/libbb.h:13, > from include/busybox.h:10, > from applets/applets.c:11: > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/bits/socke > t.h:305: asm/socket.h: No such file or directory Looks like no kernel headers are installed yet. > In file included from > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/signal.h:3 > 09, > from include/libbb.h:22, > from include/busybox.h:10, > from applets/applets.c:11: > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/bits/sigco > ntext.h:28: asm/sigcontext.h: No such file or directory > In file included from > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/sys/ioctl. > h:27, > from include/libbb.h:29, > from include/busybox.h:10, > from applets/applets.c:11: > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/bits/ioctl > s.h:24: asm/ioctls.h: No such file or directory > In file included from > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/sys/ioctl. > h:30, > from include/libbb.h:29, > from include/busybox.h:10, > from applets/applets.c:11: > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/bits/ioctl > -types.h:25: asm/ioctls.h: No such file or directory > In file included from > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/sys/param. > h:24, > from include/libbb.h:46, > from include/busybox.h:10, > from applets/applets.c:11: > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/linux/para > m.h:4: asm/param.h: No such file or directory > In file included from > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/mntent.h:2 > 6, > from include/libbb.h:52, > from include/busybox.h:10, > from applets/applets.c:11: > /usr/local/lib/gcc-lib/arm-elf/2.95.3/../../../../arm-elf/include/paths.h:35 > : config/autoconf.h: No such file or directory > In file included from include/libbb.h:702, > from include/busybox.h:10, > from applets/applets.c:11: > include/xatonum.h:86: warning: `ULLONG_MAX' is not defined > include/xatonum.h:94: warning: `ULLONG_MAX' is not defined > include/xatonum.h:130: warning: `ULLONG_MAX' is not defined > include/xatonum.h:142: warning: `ULLONG_MAX' is not defined > make[1]: *** [applets/applets.o] Error 1 > make: *** [applets] Error 2 The order I build in is: build binutils. build elf2flt aginst binutils sources (this part is rather annoying). build gcc without libraries for C only. build kernel and kernel headers and install them. build uclibc against kernel headers. build full gcc with libraries for C only (or C++ too if you are feeling lucky). build busybox. -- Len Sorensen _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
