[lfs-support] Android build buddies -- thanks!
My thanks to Firerat and DJ Lucas. I am well on my way -- I have successfully built gingerbread-release and run it in a target! DJ IMO, the biggest pain of building android is learning to use the repo DJ script instead of git by itself. Yes, that is the thing I'm still a bit fuzzy on. How do I check out a different version after fetching all those zillions of git repositories? I specified gingerbread-release on the repo init and that seems to have worked, but what if I want to try a different version? Anyhow, it's not a serious issue for me but I'd like to know. DJ I'm sure you've found this one already, at least I hope you have: DJ http://source.android.com/source/downloading.html Oh, yes, I have been there. Thanks much for the other links. I knew if I asked here on LFS I'd find helpful folks. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
Automated LFS build [was RE: Building LFS using jhlfs]
In 2009 I customized the LFS Live CD to build a bootable demonstration application. The Live CD includes makefiles that do the full build. You do a single make and hours later an .iso file pops out. The last release of the live CD corresponded to LFS 6.3. I updated the particular components I was using to the 6.4 level and I have a .tar.gz file of that if you want it. The Live CD make system is a little bit touchy but I have used it for other applications since and it's very effective. You do have to know how to handle the command line and chroot, though -- it's a bit fragile. Please feel free to contact me for details. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
Re: bootloaders and USB
What I have done is to build a grub CD that also includes copies of the kernel and initrd from the desired root device.

whoa...THAT's what I need I think. can you post an iso of that cd so I can use it as a reference? OK, you can fetch: http://msbit.com/osdv/sample-grub.iso It is grub plus the Ubuntu 9.04 kernel. You can interrupt the boot sequence and edit the kernel line to specify the desired root volume.

Re: stripping down lfs
I built a customized (somewhat stripped, then other things added) LFS back in April, 2009. It's based on the 6.3 LFS live CD with packages updated to the 6.4 book (current at the time). The LFS live CD is a very good starting point. I haven't explored other (even more stripped) alternatives like tinycore.

Re: creating my own lfs-cd
r-v-r Now I would like to create my own bootable lfs-cd. My question r-v-r is: How to do it. I recently built a custom LFS live CD for the Open Source Digital Voting Foundation. I updated the live CD makefiles to reflect LFS 6.4 (plus a few other changes) and added an application program (Pvote) and its dependencies (Python, SDL, pygame). I made it boot to the login prompt (with an empty root password), or just run the demo (with a different /etc/inittab). You can fetch my build it sources (that is, the updated makefiles, my notes, etc.) from http://msbit.com/osdv/osdvlfs.tgz A warning: My build structure is a little fragile due to my adding the Pvote application, making the live CD automatically run the demo and stripping down the final output (that was the purpose of my exercise). The default target in my master Makefile is osdv-iso, the live Pvote demo CD. The iso target still works and can be used to build a live CD with shell access, but *be*careful* to make /etc/inittab, /etc/passwd and /etc/shadow on the CD be what you really want. After completion the .iso make targets unmount everything. After building an .iso you can remount and prepare to build a different .iso by entering ./restart in the master directory (/mnt/newlfs/newlfs-livecd). The target LFS /etc files will be accessible via ../image/etc/ after remounting. Just change whatever you want and then make iso. As I wrote in the README, the live CD build environment is a little touchy and dependencies do not work fully automatically. The unmodified make from scratch works but after that you have to be careful.

Re: with new system, how to run a test boot?
There's an LFS hint describing how to boot LFS without requiring a separate partition (i.e., in the same file system as another operating system). The trick is a special pre-init program that does a chroot early in the boot process (automatically, rather than manually as Russell Stockhammer suggests).

re. Village Idot question. How do I start? [LFS]
I like the idea behind LFS and would like to explore all of the options. LFS offers better control over the process. LFS is an excellent project and I think it will suit your needs as a starting point; as Ken Moffat points out, you will have some further work to do on cross-platform development. I started by following the 6.4 book instructions manually, with one slight modification -- I used the next to existing systems hint, which includes a special pre-init program that does a chroot early in the boot process. Thus, after building LFS I could boot either my regular system or test the system built in /LFS (my LFS build location) without changing any disk partitions. [http://www.linuxfromscratch.org/hints/downloads/files/lfs_next_to_existing_systems.txt] Be sure to read the errata list for the manual -- there are a few fixes. [http://www.linuxfromscratch.org/lfs/errata/stable/] I also wanted to add an application and make a live CD, so once I had the base LFS working I started looking at the LFS Live CD project. The build structure for the live CD has a Makefile that automatically fetches sources via wget and builds everything with a single make, all the way to generating an .iso file. It seemed ideal for my purposes. Alas, that project is a little behind the times -- LFS itself was at 6.4, but the LFS Live CD project is at 6.3. I upgraded the packages I needed and hacked up the Makefile to add my application. Of course, now I'm behind too because 6.5 is about to come out. My particular interest was to build a demo of a minimum system including only components necessary to run the application (Pvote). So my build has an additional step that leaves out some libraries and most of /usr/bin. However, I left the regular iso target intact and after building my demo a make iso works to build the regular LFS. I did *not* bring all the additional BLFS components up to date because I was only aiming at a minimal system. My build LFS tar ball (that is, the updated makefiles, my notes, etc.) might be a helpful base for you. You can fetch it from http://msbit.com/osdv/osdvlfs.tgz Nowadays, because I'm building a live CD, I test by booting the .iso in a VMWare virtual machine. That works well. I have also gotten KGDB to work via a virtual serial port. I retested my build just last week and found that a couple of sourceforge links had changed (e2fsprogs and tcl), so I made a patch to fix that. After installing the tar ball, cd /mnt/newlfs/newlfs-livecd; patch -p0 lfs-sourceforge-patch Also, see the note I posted last week: http://linuxfromscratch.org/pipermail/lfs-support/2009-July/036151.html lfs-sourceforge-patch - diff -Naur packages/e2fsprogs/Makefile updated-packages/e2fsprogs/Makefile --- packages/e2fsprogs/Makefile 2009-04-14 21:57:02.0 -0700 +++ updated-packages/e2fsprogs/Makefile 2009-07-29 08:56:46.0 -0700 @@ -8,7 +8,7 @@ DIR= $(NM)-$(VRS) FILE= $(DIR).tar.gz -URL-$(FILE)= http://superb-west.dl.sourceforge.net/sourceforge/e2fsprogs/$(FILE) +URL-$(FILE)= http://softlayer.dl.sourceforge.net/project/e2fsprogs/e2fsprogs/$(VRS)/$(FILE) SHA-$(FILE)= d85f05b7bcef1adf8306a789f3ac0325c3c67e8d # Targets diff -Naur packages/tcl/Makefile updated-packages/tcl/Makefile --- packages/tcl/Makefile 2009-04-14 21:45:51.0 -0700 +++ updated-packages/tcl/Makefile 2009-07-29 08:56:18.0 -0700 @@ -5,7 +5,7 @@ DIR= $(NM)$(VRS) FILE= $(DIR)-src.tar.gz -URL-$(FILE)= http://superb-west.dl.sourceforge.net/sourceforge/tcl/$(FILE) +URL-$(FILE)= http://softlayer.dl.sourceforge.net/project/tcl/Tcl/$(VRS)/$(FILE) SHA-$(FILE)= af0433feaa7be1da945a1f414c4b10485ffbd386 # Targets -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

error installing e2fsprogs
On a whim, I renamed the executable /tools/bin/touch and created a symlink from /bin/touch (the app from the host system) and the make completed and the app install without errors. Could this be a mis-step when I installed the coreutils? I hit this too. It's due to building on an old system. There was a change (utimensat) that the latest glibc and touch use to update a timestamp. (I grumbled for a few minutes when I discovered this -- why is there a change to this ancient function?) See, for example, http://bugs.gentoo.org/show_bug.cgi?id=224483 Anyhow, your fix should work for now but you probably want to upgrade the kernel, glibc and coreutils on the build system.

re. Kernel panic - not syncing: Attempted to kill init!
You write that the kernel has successfully mounted the root file system. Are you sure? This kind of crash is often due to a failure to mount /. How is the CF card connected physically? You also write you have no initramfs. I suggest you create one -- then if initialization cannot mount root it will drop into a shell and you can examine the kernel boot messages. Be sure to include dmesg, grep, more and so on in your initramfs so you can look around easily. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
LFS Live CD future direction -- a suggestion
First, I want to thank everyone involved in creating the LFS project. It is a beautiful piece of software craftsmanship -- useful, elegant and well documented. I'm writing this post because I have a suggestion for the Live CD part of the LFS project. I went back and read the Live CD mailing list archive and there was a request looking for future directions posted back in October of 2008. After I built LFS manually, I decided to try using the Live CD makefiles to automate the build of a system I customized. This was a somewhat complex undertaking but I finally made it work. My suggestion is: enhance the Live CD structure to be a platform for creating minimal Linux system source code development environments. I ran across LFS while searching for a starting point for a project: the Open Source Digital Voting Foundation aims to create a minimal, verifiable platform for development of reliable election systems. As a proof of concept prototype, I used LFS to build a live CD demonstration version of Pvote, Ka-Ping Yee's voting thesis project. A major reason for wanting to minimize the sources is to make a source code inspection of a proposed voting system practical. As a first cut at creating a minimal system, after a complete LFS build by the book, I removed libraries and executables that were not required for a skeleton system. I was able to omit almost all of /usr, as well as a bunch of libs. I have not yet tried to go back and isolate which sources could be left out of a build -- that is the next step. The Live CD makefiles fetch sources and deliver a working bootable CD. The basic idea is, type make and hours later a live CD pops out. This works, but it is not an ideal structure if a developer has to do further work to customize the system. For example, the build process destroys the intermediate results (object files) after each component is completed. Also, the make file dependencies are incomplete, so a change may require a developer to know which rebuilds need to be forced (initramfs falls in this category). Don't get me wrong: the LFS Live CD was a great starting point for what I needed, and it only took a week or so of manual work to upgrade it to LFS 6.4+, add the Pvote requirements and cut the unnecessary parts. But that still is only a start. My work has many rough edges, nowhere near as polished as LFS or the LFS Live CD themselves. I think many people have a need to build custom live CDs and this would be a fruitful path for future LFS Live CD work. Having an LFS Live CD development environment as a starting point would benefit them. -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page
