I'm still > curious about this. a few differences, quite minor actually (that's why I said in the past we shared many common goals :-) )... I actually started this in 2002, but then hit many bugs in uclibc. In the end, I actually used a trimmed LFS approach, using zisofs. My bootable env then was ~45Mb. At that time, buildroot was also starting... I lacked of time to work on it. The biggest difference today is that your firmware is based on automation or Makefiles, whereas I still use a LFS type of approach. I first build a static minimal toolchain with a static busybox: all native, no cross compilation. Then I chroot in it, compile uclibc, busybox, the toolchain. The rest is obvious, but quite manual. I really should do Makefiles... The other difference is that I base detaolb on aufs/squashfs (I do not think you passed that stage yet, if I recall not all the archs you're targetting can take this). That's today's improvement over the stuff I did in 2002 using zifofs. > Oh, by the way, the Fedora for Arm project is also building natively on arm, > but they got some fast ARM hardware and stuck lots of DRAM and hard drive > space onto it rather than using QEMU. in 2003/2004, I also worked on porting linux to an Ipaq h2215. I actually then used buildroot arm precompiled, and managed to chroot in it using nfs over usb. quite cool, and the speed was better than qemu today. It was just a 400Mhz Xscale. I'm still interested in your cross compiling tutorial. I believe we all are :) If I start putting too many archs in the picture, I believe DetaolB will be redundant with Firmware. This is not intended. Originally I wanted to share the portable x86 env I carry on my usb key. Some of you asked for a sparc32 port. I'll complete this one at least (I'm progressing quite fast on it). -- Christian -- http://detaolb.sourceforge.net/, a linux distribution for Qemu
