Message-ID: <20040911202548.GA31680@MAIL.13thfloor.at> Mail-Followup-To: Sam Ravnborg , linux-kernel@vger.kernel.org Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.4.1i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi Sam! first, thanks for the kbuild stuff and all the time spent on that ... I really love it from time to time I encounter some issue which usually keeps me busy for a while, and I think there probably is a simpler solution to that ... the procedure: I'm configuring a 2.6.X-rcY-bkZ kernel for testing with QEMU, which in my setup basically requires some QEMU specific settings, I usually turn on/off by just editing the .config file by hand, and then invoking 'make oldconfig' ... to keep the possibility for error low, I usually just remove the entries in question, and oldconfig will ask me the relevant question, leading to a nice config adapted to my purposes ... the issue: sometimes a dependancy doesn't allow me to remove a config option, I absolutely have to remove for my setup, like the VGA_CONSOLE, and then the hunt for the option 'requiring' that one unconditinally beginns ... usually I start with grep and end with trial and error, until I find the malicious dependancy ... so, now the question: is there a magic option, simple procedure, or just quick and dirty hack to get a list or some kind of dependancy graph from the kbuild system? TIA, Herbert
