Re: [kbuild-devel] linux kernel conf 0.6
Hi, (I almost forgot to reply to this one, sorry for the delay.) On Sun, 22 Sep 2002, Kai Germaschewski wrote: I'm not particularly fond of these md5sum hacks. 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) Where's the problem with md5sum? If the rules are usually not visible anyway, why do we use the _shipped postfix at all? The depencies are hidden this way as well, so make won't even try to regenerate the file. The developer has to remember that extra argument to get the file regenerated, what is IMO more hacky than using md5sum. 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

I think there's hardly anyone who wants oldconfig in that case, rather menuconfig/xconfig or a cp like I mentioned. Since kbuild/lkc does not know, it shouldn't make that (bad) guess. If .config exist but is not current, I think in 99% of the cases we really want make oldconfig, so that's fine. --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

Thanks, nice work. :) Rules.make - Added infrastructure to support host-ccprogs, in other words support tools written (partly) in c++. There are all compiled with gcc instead of g++, are you sure that will ok with all supported gcc versions? scripts/lkc/Makefile* - As kbuild does not distingush between individual objects, used for a given target, but (try to) build them all, I have found a solution where I create one Makefile for each executable. I could not see a clean way to integrate this in kbuild, and finally decided that in this special case a number of Makefiles did not hurt too much. Here I thought about using ifeq ($(MAKECMDGOALS),...) to keep them in a single file. Did you try something like this? flex/bison - Prepared for _shipped files. Rename lex.zconf.c to lex.zconf.c_shipped etc. in the version reday to go in the kernel. 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

(But I'm not particularly good at coming up with names ;) build.conf is maybe not too bad considering that there may be a day where it is extended to support driver.conf as well. One other thing I wanted to mention but forgot was that lkc now does a quiet make oldconfig when .config changed or does not exist, which is changed behavior.

The proper behavior for this example is cp arch/$arch/defconfig .config Do a 'make oldconfig' or 'make config' with no .config, in a 2.4 kernel. Please fix... :/ Same thing for - [kai@zephyr linux-2.5.make]$ cp ../config-2.5 .config [kai@zephyr linux-2.5.make]$ make make[1]: Entering directory `/home/kai/src/kernel/v2.5/linux-2.5.make/scripts' make[1]: Leaving directory `/home/kai/src/kernel/v2.5/linux-2.5.make/scripts' *** *** You changed .config w/o running make *config? *** Please run make oldconfig *** - Since people run automated builds, erroring out is IMHO preferable to dropping into interactive mode, which likely happens when you run make oldconfig. agreed Jeff --- 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
