how to update install CD ?
by 董洪乾 18 Jan '08

18 Jan '08

Hello, everyone: I want to add new rpm into install cd . I have searched the answer on the net and done it like what they have said. But when I use the cd I made to install OS, It told me that " The CentOS-4 i386 CD was not found in any of your CDROM drivers. Please insert the CentOS-4 i386 cd and press OK to retry". I don't know why. Could anyone help ? The following is the step : pkgorder --product CentOS /data/CentOS/ CentOS > /data/pkgfile genhdlist --productpath=CentOS /data/OWLinux pkgorder --product CentOS /data/CentOS/ CentOS > /data/pkgfile buildinstall --pkgorder /data/pkgfile \ --version "4" \ --product "CentOS" \ --release "1" \ --prodpath CentOS /data/OWLinux mkisofs -J -R -v -T -o ./CentOS.iso -V CentOS-4 -b \ isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot \ -boot-load-size 4 -boot-info-table ./CentOS/ Best regards ! dhongqian 2008-01-16

Thank you...Daneil and John... My device configuration is as follows. CPU : intel Celeron M 1.60 Ghz DIMM : W/DDR 1GB ECC IDE(Primary Master) : Compact Flash (1 GB) IDE(Primary Master) : Compact Flash (256 GB) My confusion is that if it is possible to customize the CentOS for my application.

That's also correct. But not because of the distribution I am blaming ARM. The performance got degraded very much in arm.

There you have the explanation. :-) *runs* More seriously, don't blame the CPU for the shortcomings of the distro you were using. There are enough distros that run on ARM that aren't similarly crippled. _______________________________________________ CentOS-devel mailing list CentOS-devel(a)centos.org http://lists.centos.org/mailman/listinfo/centos-devel

I have worked with arm...but it is a night mare for me...i don't know from where all dependency problems comes...and also cross compiled libraries freely available ... were having many issues... my test machine was i686... and I had to port a gtk application in arm board ..the os I used was montavista linux ...many of may features did not work in board..

That's somewhat unlikely. :) But there _are_ probably an order of magnitude more ARM CPUs in the world than x86 CPUs. _______________________________________________ CentOS-devel mailing list CentOS-devel(a)centos.org http://lists.centos.org/mailman/listinfo/centos-devel

CentOS-5 Cross-Build Environment (arm, mips, sparc, others..) / pre-alpha released
by Brian Schueler 15 Jan '08

15 Jan '08

Hi, folks. I've begun to work on a cross-build environment hopely to make CentOS 5 run on other architectures than supported by CentOS yet and that supported by the PNAELV. This project comes with a patch for the glibc 2.5 with added support for architectures like arm, mips, ppc, alpha, etc. to generate a cross-compile toolchain (cross-compilers, assemblers, linker/loader). It runs quite well with the Timesys 'tsrpm' tool (which is compatible with that project). Many RPMs does cross-build very well, but others fails on sanity checks, incompatible configure scripts, etc. (Kernel compilation is not included at this time.) Note that software created through that toolchain is not binary compatible to anything released by CentOS or the PNAELV. I want to switch to 'mock' and - I need a lot of help with its internals. The best enhancement were that 'mock' could recursively rebuild software entirely from source (using a yum repository that _only_ provides SRPMS). - only needing compiling natively (host-arch = target-arch). And there are many things to discuss at one event (glibc, cross-compiling, Kernels, automated RPM cross-(re)build machinery, repository management, yum-bootstapping, etc.) IMPORTANT: This is my first version - so please consider my project as unstable/pre-alpha. My wish is to make this project work as desired to bring CentOS to many more architectures and hopely to make it part of the CentOS project. This is leaned to Cross Linux From Scratch and is licensed under the terms of the GNU GPL v2. The tree is located at: http://dbl76.tfh-berlin.de/~s18009/c5/cross reviews, improvements, suggestions, bug reports are very welcome. - BriSch

Thank you all for the enormous suggestions and information's ... I think I can go forward with the customization. Many suggested using Debian instead of CentOS... Why I prefer CentOS is that CentOS is more stable than Debian or any other editions... and there will be less dependency problems (I think so) Regards Vishak V Kurup -----Original Message----- From: centos-devel-bounces(a)centos.org [mailto:centos-devel-bounces@centos.org] On Behalf Of John Summerfield Sent: Saturday, January 12, 2008 4:43 AM To: The CentOS developers mailing list.

CentOS 4.6, buildinstall and bogl font problem
by James Pearson 14 Jan '08

14 Jan '08

I'm trying to rebuild a custom 4.6 installer using /usr/lib/anaconda-runtime/buildinstall (from anaconda-runtime-10.1.1.81-1.centos4.1), but it gives the following warnings/errors: Creating bogl font.. zcat: /tmp/treedir.4539/instimage/usr/lib/bogl/font.bdf.gz: No such file or directory cat: /tmp/treedir.4539/instimage/usr/lib/anaconda-runtime/unicode-linedraw-chars.txt/disk1/distro/CentOS/4/i386/os/buildinstall.tree.4526/upd-instroot: line 939: /tmp/treedir.4539/instimage/usr/bin/reduce-font: No such file or directory: No such file or directory find: msgunfmt terminated by signal 13 find: msgunfmt terminated by signal 13 ...(repeats until)... find: msgunfmt terminated by signal 13 /disk1/distro/CentOS/4/i386/os/buildinstall.tree.4526/upd-instroot: line 940: /tmp/treedir.4539/instimage/usr/bin/bdftobogl: No such file ordirectory gzip: /tmp/treedir.4539/instimage/usr/lib/anaconda-runtime/loader/font.bgf.gz already exists; do you wish to overwrite (y or n)? ... and buildinstall waits until you type y or n. If you type "n", then you end up with an empty font.bgf.gz file ... It appears the /usr/lib/anaconda-runtime/upd-instroot script wants to create it's own font.bgf.gz, but it can't find the bits to do this. Also, /usr/lib/anaconda-runtime/loader/font.bgf.gz already exists as part of anaconda-runtime, so I'm not sure why it is trying to re-create this font file. I can hack /usr/lib/anaconda-runtime/upd-instroot to skip this, but I guess I must be doing something wrong as this shouldn't happen ... Thanks James Pearson

Use CentOSplus to carry latest GUI packages
by Ross S. W. Walker 11 Jan '08

11 Jan '08

I don't know if this has been talked about much in the past, but I was wondering if CentOSplus could be used to carry the latest stable versions of the GUI applications KDE/Gnome. These apps often lag behind quite a bit even on the selected stable branch upstream has chosen. For example, would it decrease stability to update KDE from 3.5.4 to 3.5.8? I think it would add to stability as long as you stay within that 3.5 branch, but upstream thinks otherwise and tries to re-invent the wheel by backporting 3.5.5-3.5.8 fixes into 3.5.4 which often don't work completely and have the potential of creating new bugs themselves. Another thing, Xen, the Xen package says it's 3.0.3, but looking at the SRPM it turns out it's the Xen 3.1 kernel with the Xen 3.0.3 'xm' and 'xend' dom0 utilities. In my book that's Xen 3.1, why not just fix the parts of the 3.1 utilities that broke between releases? Anyways Xen may not be a good candidate as others may have environmental dependencies on the upstream version, but upgrading to the latest minor version within a branch for a given application shouldn't break environmental dependencies, ie provide Xen 3.1.4 if it contains the xm and xend fixes that upstream was looking for. What is the consenus on this? -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

centos-release for 4.6
by James Pearson 11 Jan '08

11 Jan '08

Something that is puzzling me - why is the centos-release RPM for CentOS4.6 called centos-release-4-4.4 - shouldn't it be named something like centos-release-4-6.X ? Also, the centos-release-4-4.4.src.rpm doesn't appear to be on 4.6 SRPM DVD ISO image ... James Pearson
