The proper behavior for this example is cp arch/$arch/defconfig .config Do a 'make oldconfig' or 'make config' with no .config, in a 2.4 kernel.

Can you elaborate a bit on that? 'make oldconfig' is one of the things we want to keep working as-is... That was a downside of ESR's system.

I don't think it's all that annoying for the developer, either, it's basically just a alias make="make LKC_GENPARSER=1" (Of course, you'll have to update the _shipped files eventually, but there isn't really any way around that either way) One might consider setting LKC_GENPARSER based on a test if bison/flex are in the path. > Something else I'd like to have for later is the ability to compile > $(sharedobjs) as a shared library and install it somewhere so it can be > used by external programs. Well, later ;) --Kai I created a combined patch with lkc-0.6, Sam's patch and my things on top of current 2.5-bk (And I would strongly suggest to make further releases like this, if people need to first figure out how to install and what to run, they won't test lkc at all). As a result, it's fairly large, so I put it on http://zephyr.physics.uiowa.edu/~kai/lkc/lkc-0.6-A --Kai --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ kbuild-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/kbuild-devel

This works quite well for users, but it's very annoying for the developer. Kai, any chances to use md5sum for this at some point, e.g. with a helper script like this: set -e src=$1 dst=$2 shift 2 test -f $dst && tail -1 $dst | sed 's,/\* \(.*\) \*/,\1,' | md5sum -c && touch $dst && exit 0 echo "$@" "$@" echo "/* $(md5sum $src) */" >> $dst The only problem with this script is that it only supports a single input and output file. Something else I'd like to have for later is the ability to compile $(sharedobjs) as a shared library and install it somewhere so it can be used by external programs. bye, Roman --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ kbuild-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/kbuild-devel
