Thank you Andriy, I have seen your post earlier here: https://lists.tizen.org/pipermail/general/2014-March/002935.html. I am sorry, I didn't I quite understand it. Looks like I need some handholding here. Can you share the helper scripts and elaborate the instructions a bit more. Since you have already traveled this path, you may share those helper scripts and more details guidelines on Tizen Wiki before those scripts are accepted into public repos? Your help is much appreciated.

These rpms will be used as pre-builts. For this bootstrap procedure we did some helpers scripts: - it takes sources from Tizen repo and crosscompile them for initial buildroot - then it builds list of rpms from source rpms - we used it to prepare mipsel pre-builts but it can be used for any other arch after some improvement. If such tool is interesting for Tizen maintainers we can put it in Tizen public repo. Regarding toolchain(binutils, libc, gcc): we dont build separated gcc, libc, binutils. We split separated cross-toolchain in several rpms: - qemu-accel - to emulate target compilation with host crosscompiler - libc - runtime libraries and binaries - libc-devel - devel files - headers and libraries - gсс, binutils, etc - fake rpms to emulate target compilation with host crosscompiler More details we are going to document for Tizen wiki.

But there are lot of packages which are not there in Mentor tool chain. How to get the tool chain for MIPS. Are there any tool chain sources repos, from which I can build cross platform toolchain for MIPS? If yes, how to build them? Regards, Murthy NSSR.

Feel fre to notify me if any changes needed in them. Whould be great if you can answer this also: Also, take a look into patch for qemu at the end of the page here http://patchwork.ozlabs.org/patch/250161/ . It hould be aplied if you want qemu to work properly for mipsel. One more question about qemu, we have fixed mask for qemu-reg( /usr/lib/build/qemu-reg from build package ) for mipsel platform and don't know where to submit it. Whould be great if anyone can help us with that. Don't we need any changes to scm/meta/build-config/build. conf file like "Optflags" for architecture specific compiler options? Not shure, we have a lot of things changed because of platform specifics, but can't find anything mips related And I see there are many "%ifarch %{arm}" in spec files of various packages? Do we need to do something here to be MIPS specific? Most of our changes in .specs where specific to our platform. But you would need to look into patch http://patchwork.ozlabs.org/patch/250161/ and fix qemu-reg(we will contribute fix as soon as we know where to contribute) On Wed, Oct 8, 2014 at 10:29 AM, JF Ding < [email protected] > wrote: <blockquote> Sorry for noticing these patches of building tools so late, because we were rotating the maintainers those days.

We are more focused on Tizen wear. ok then I guess you want to build this profile : https://build.tizen.org/project/show?project=Tizen%3A2.3%3AWearable Make sure you have every sources because IICR there are binary blobs (ARMv7l) in this profile > If we go ahead with Tizen 3.0 common and 3.14 Kernel, we can get the base > work required for bringing up Tizen wear. > But there seems to be no Tizen wear profile on Tizen 3.0 till now.

Sorry I don't know any, may others in this list give you better hints I can only help you to have MIPS support for Tizen:Common in hope it will be available for downstream profiles (ie: IVI at the moment) Good luck -- mailto: [email protected] -- gpg:0x467094BC xmpp:[email protected] https://dockr.eurogiciel.fr/blogs/embedded/author/pcl/ . _______________________________________________ Dev mailing list [email protected] https://lists.tizen.org/listinfo/dev -- Andrii Boichuk | Software developer GlobalLogic M +38.063.427 .1605 S liberus.ua www.globallogic.com .ua http://www.globallogic.com/email_disclaimer.txt _______________________________________________ Dev mailing list [email protected] https://lists.tizen.org/listinfo/dev </blockquote> </blockquote> -- Andrii Boichuk | Software developer GlobalLogic M +38.063.427 .1605 S liberus.ua www.globallogic.com .ua http://www.globallogic.com/email_disclaimer.txt _______________________________________________ Dev mailing list [email protected] https://lists.tizen.org/listinfo/dev _______________________________________________ Dev mailing list [email protected] https://lists.tizen.org/listinfo/dev _______________________________________________ Dev mailing list [email protected] https://lists.tizen.org/listinfo/dev </blockquote> -- Andriy Prystupa | SW Engineer GlobalLogic P +x.xxx.xxx.xxxx M +38.097.330.9412 S prandriy www.globallogic.com http://www.globallogic.com/email_disclaimer.txt
