Grip isn't actually built from source, at least not directly. It is built from Debian binaries which are natively built from source by the Debian buildd system. To build an Emdebian Grip mirror, you simply use the emdebian-grip-server package and download the built binaries from Debian. Grip is *not* about rebuilding packages, it repacks existing, natively built, packages from Debian. To build new packages for Grip, first build them for Debian (using dpkg-buildpackage) on a native system (or suitable i386 chroot) and then use emgrip on the results. Do not use 'dpkg-buildpackage -a' for Grip, just dpkg-buildpackage. > Arch: i386 > > I use emdebuild -a i386 for that. emdebuild builds for Crush, not Grip. Crush removes more files because it passes more options to emgrip. Grip uses DEB_BUILD_OPTIONS="usegrip" and Crush uses DEB_BUILD_OPTIONS="usecrush" - the differences between the two are described in the emgrip manpage. To simply grip a package that has already been natively built by Debian, just use emgrip. See emgrip (1). Mixing packages from Crush (emdebuild) with ones from Grip (emgrip alone) is untested (but may be necessary in some cases where emdebuild would fail - i.e. the reverse of what you are doing). Using the latest emdebian-tools from unstable, you'll be able to see this in the package description - if you use emdebuild, the package will describe itself as (crushed) and as an "Emdebian Crush package". If you use emgrip on a natively built package, it will describe itself as (gripped) and as an "Emdebian Grip package". Use debdiff to compare the final .deb files (you can also compare the .dsc and .changes with debdiff.) Crush does not need to support building packages on a system running Crush, so it ditches parts of packages that are build-system related. Grip preserves such files. > For example, I'm trying to build a a2ps_4.14 package. > After the process is finished I have a2ps_4.14-1em1_i386.deb, > but it's size is 675740 when the size of a2ps_4.14 package from > repository is 682004. > > Is it normal ? the same situation with many other packages. A different md5sum and a difference of a few bytes in two Grip packages is entirely normal because the package is being unpacked, modified and then repacked and 'dpkg-deb' tends to make different sizes when repacking the same files on different systems. The other difference is because you are comparing a package for Grip with a package for Crush. -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
