There's no point in using emdebian-tools natively. Just use dpkg-buildpackage as normal and then post-process using emgrip if necessary. Alternatively, if you want the busybox based system without perl, you should use the existing packages from Crush as source packages for your own native builds so that you get the patches already applied. > We are going to build our own PowerPC distribution (targeting a > embedded system) based on the Emdebian package customization > (DEB_VENDOR, etc).

Crush is a cross-build, Grip is built from natively built packages. The experiments with Crush would have bolted the Grip process onto the end of the cross build which also allows the same process to be used for native builds. > From my past experience with the cross-toolchains and cross-builds, I > remember how painful could be a build process (used Den Kegel > crosstool scripts to build a toolchain; libtool-based packages was the > real problem to build in cross).

If you try a rebuild from the Emdebian Crush source packages, you will get the original Lenny versions, not the updated ones with security fixes etc. and you will be locked into those versions forever. If you can live with coreutils and perl, just use Emdebian Grip. > to rebuild the Emdebian distribution (the > target part of it) with my changes in package list, packages > configurations, install scripts, etc? If you want a system without perl and coreutils, based on busybox etc., then you are going to have to do most of that work all over again for yourself. > My plan is to run the emdebian-tools on a PowerPC system (a fast > powerpc board with NFS-mounted Debian rootfs) to produce a PowerPC > target distribution packages.

Can you use coreutils and perl or must you have busybox? -- Neil Williams ============= http://www.data-freedom.org/ http://www.linux.codehelp.co.uk/ http://e-mail.is-not-s.ms/
