Re: [PATCH] Dpkg/Shlibs.pm: multiarch search paths

Emdebian Crush stalled after Lenny (and used ARM not armel), so the version of gcc-4.2 in Lenny should still build with the typical "dpkg-buildpackage -aarm". Later versions of gcc probably have other fixes which would cause the reverse cross build to fail, not due to the failure of the original patches but due to changes in gcc itself. To create a fully bootstrap-able system, gcc does need to support the reverse cross and this will need testing in Multi-arch world. Typically, gcc-4.* *should* be expected to build correctly just using: $ dpkg-buildpackage -a$arch No special target specification (except internally in debian/rules etc.), no expectation of building a cross-compiler, just building it as if it is any other package which needs to be cross-built. Of course, if libgcc1 can be made available in any other way than having to pretend that we actually want a native compiler on these systems (99% of the time we really don't), then everyone wins. > Neil (or anyone else knowledgable on the topic), can you review the > patches and tell us what's really needed and most logical according to > you? > > Steve's patch: > - adds the multi-arch path at the start of the search paths > - adds them only for stantard cross-compilation (host != build) but not > for the special cases used to detect a cross-compiler build Intuitively this does sound the correct way to do it, especially as what I wanted from the original patch was a standard cross-build, not the special case of building a cross-compiler, but: > My patch: > - adds the multi-arch path before the cross-arch patch but after the > standard search path > > - add them in all cases where the cross-compilation paths are used > > Putting the multi-arch paths after the default path should not matter as > dpkg-shlibdeps skips libraries of non-matching architecture. This is more in line with how it actually works out when trying to cross-build gcc itself. I'm not sure of the benefit of putting the multiarch lib location in front of the default lib location. I'm not sure if having some i386 libraries in a multi-arch path and the main system amd64 libraries in a non-multi-arch path would actually matter (after all, the same libraries *should* get updated together). That's a "traditional" Multi-Arch question, so I'd defer to Steve on that one. For cross-building, it's simply sufficient that the new multi-arch-cross paths precede the old dpkg-cross paths and both patches achieve this. > For the case of building a cross-compiler, Steve's experience tends to > prove that adding the multi-arch path is not needed... but I don't see why > it should be treated differently than the cross-arch paths. > > Can you enlighten us? For building a cross-compiler, Steve is correct - it doesn't matter. For using that cross-compiler to cross-compile gcc itself, it will matter. Multi-Arch paths will be necessary to build a version of libgcc1 which can be installed on the target. -- Neil Williams ============= http://www.linux.codehelp.co.uk/

LinaroAndroidBuildService

by Guilherme Salgado

Hi Michael, That wiki page[1] gave me a good overview of the build service; I have only a couple questions. Also, even though I didn't actually read most of the code, I saw some shell script to configure the build slave and I'm wondering if you think it'd be worth using something like puppet for that instead. The scripts seem small enough at this point, so it may not worth the effort at this point, but I'm sure they'll grow over time and we don't want to end up with a mess similar to the old l-m-c. > SCRIPT_NAME: Defines the name of the[...] At first I thought it'd be nice to have a short description of the existing scripts here, but it looks like we only have the regular one and an extra for building with a custom toolchain, so maybe it's not neeeded? > To get your script into the branch used by the build system, > submit a merge proposal to [...] I guess that means the jenkins job created under the hoods will always use the tip of the build-tools branch, avoiding the need for a manual update?

[PATCH] dpkg-cross: handle multi-arch packages too

by Marcin Juszkiewicz

Hi Ubuntu 'natty' switched to multiarch recently and my cross toolchain packages started to fail to build. Most of problems were fixed but then dpkg-cross hit us. Today I looked at dpkg-cross and made attached patch to handle problem. What patch does is converting multiarch packages into old style ones. There is no extra switch like "--force-even-when-multiarch" and "--convert-anyway -A" is used instead. This is change against latest CVS code (dpkg-cross r1.83). >From my tests it looks like it does proper job.
