I have this old AP from Linus (Torvalds) to make the kernel build with arm-none-* baremetal compilers, currently there are more than a few obstacles to this: https://lkml.org/lkml/2011/10/28/76
In this case: -#ifdef linux +#if defined(linux) || defined(__KERNEL__) #ifdef __KERNEL__ ... Which was tentatively ACK:ed by Torvalds. -- You received this bug notification because you are a member of Linaro Maintainers, which is the registrant for Linaro Linux. https://bugs.launchpad.net/bugs/868550 Title: __linux__ is not getting defined in android-build Status in Linaro Android: Fix Released Status in Linaro Linux: New Bug description: On 5 October 2011 09:03, Andy Green <[email protected]> wrote: > On 10/05/2011 09:54 PM, Somebody in the thread at some point said: >> >> On 5 October 2011 08:39, Andy Green<[email protected]> wrote: > >>> #else /* One of the BSDs */ >>> >>> >>> #include<sys/ioccom.h> >>> >>> I assume you don't mean to be building for BSD. >>> >>> It looks like the way you build the kernel is broken. >> >> Hmm...

Yup. We're one the latest and greatest from Linaro. Its always listed on the build page at: https://android-build.linaro.org/builds/~linaro-android/tracking- panda/ I've tried both: build 3: https://android-build.linaro.org/jenkins/job/linaro- android_toolchain-4.6-bzr/33/artifact/build/out/android-toolchain- eabi-4.6-33-2011-10-03_00-11-15-linux-x86.tar.bz2 build 4: https://android-build.linaro.org/jenkins/job/linaro- android_toolchain-4.6-2011.09/1/artifact/build/out/android-toolchain- eabi-linaro-4.6-2011.09-1-1-2011-09-16_16-16-01-linux-x86.tar.bz2 (Linux/GNU Binutils) 2.21.53.0.2.20110804 gcc version 4.6.2 20110908 ...for make we're at Natty Narwhal at the moment. Bero or Ken do you guys know where __linux__ gets defined in the build chain? Is this a regression? Bero, would you mind taking a look? > -Andy > > -- > Andy Green | TI Landing Team Leader > Linaro.org │ Open source software for ARM SoCs | Follow Linaro > http://facebook.com/pages/Linaro/155974581091106 - > http://twitter.com/#!/linaroorg - http://linaro.org/linaro-blog > -- Zach Pfeffer Android Platform Team Lead, Linaro Platform Teams Linaro.org | Open source software for ARM SoCs Follow Linaro: http://www.facebook.com/pages/Linaro http://twitter.com/#!/linaroorg - http://www.linaro.org/linaro-blog To manage notifications about this bug go to: https://bugs.launchpad.net/linaro-android/+bug/868550/+subscriptions -- Mailing list: https://launchpad.net/~linaro-pkg Post to : [email protected] Unsubscribe : https://launchpad.net/~linaro-pkg More help : https://help.launchpad.net/ListHelp
