bitbake.conf: define WORKDIR in terms of BASE_WORKDIR

2013-09-22T11:19:32+00:00

To make it easier to move WORKDIR, define it using the new variable BASE_WORKDIR, which is the root of the work directory. (From OE-Core rev: 1eee097f2e29b9d6934711c0b1d32e59e9542f53) Signed-off-by: Ross Burton Signed-off-by: Richard Purdie

bitbake.conf/package: Collapse PKGDATA_DIR into a single machine specific directory

2013-09-14T07:21:00+00:00

Currently we have a hierarchy of pkgdata directories and the code has to put together a search path and look through each in turn until it finds the data it needs. This has lead to a number of hardcoded paths and file globing which is unpredictable and undesirable. Worse, certain tricks that should be easy like a GL specific package architecture become problematic with the curretn search paths. With the modern sstate code, we can do better and construct a single pkgdata directory for each machine in just the same way as we do for the sysroot. This is already tried and well tested. With such a single directory, all the code that iterated through multiple pkgdata directories and simply be removed and give a significant simplification of the code. Even existing build directories adapt to the change well since the package contents doesn't change, just the location they're installed to and the stamp for them. The only complication is the we need a different shlibs directory for each multilib. These are only used by package.bbclass and the simple fix is to add MLPREFIX to the shlib directory name. This means the multilib packages will repackage and the sstate checksum will change but an existing build directory will adapt to the changes safely. It is close to release however I believe the benefits this patch give us are worth consideration for inclusion and give us more options for dealing with problems like the GL one. It also sets the ground work well for shlibs improvements in 1.6. (From OE-Core rev: 1b8e4abd2d9c0901d38d89d0f944fe1ffd019379) Signed-off-by: Richard Purdie

bitbake.conf: include machine name in DEPLOY_DIR_IMAGE

2013-09-14T07:21:00+00:00

This allows a clean seperation between image outputs from different machines, and makes it possible to have convenience symlinks to make the output ready to deploy. This did require some surgery in runqemu; if explicit paths to the image and kernel are not supplied then DEPLOY_DIR_IMAGE needs to be determined from bitbake or set in the environment. However the script does try to avoid requiring it unless it really is needed. Corresponding changes were made in the automated testing code as well.

bitbake.conf: Stop providing ${P} and ${PF} by default

2013-09-14T07:20:59+00:00

For a long time we've provided PN-PV and PN-PV-PR by tweaking PROVIDES. This looks nice at first glance however it turns out to be a bit problematic. Taking make as an example where there are two versions, 3.81 and 3.82, what should "bitbake make-3.81" do? Currently it builds make-3.81 and make-3.82 and breaks in interesting ways. Is that a bitbake bug? Well, it certainly shouldn't try and run the build. Why is it building 3.82 though? Its due to finding a dependency on "make-dev" and then trying to figure out what provides it? The answer is "make" and the default version of "make" is 3.82. So arguably, finding "make-3.81" should infer PREFERRED_VERSION_make = "3.81". Doing so resolved the above problem since now "make" resolves to "make-3.81". So what about if we have Recipe A: DEPENDS = "make-3.81" and Recipe B: DEPENDS = "make-3.82" That is clearly an error, easy. So finally what about if we have Recipe A: DEPENDS = "make-3.81" and Recipe B: DEPENDS = "make" The first recipe infers the PREFERRED_VERSION_make = "3.81" and then forces that version on everything else. Is that desired? Probably not in most cases, at least not silently. As mitigation, we could print a WARNING about this happening. The final part of the problem is that we can ony figure this out within bitbake itself. That means we'd have to teach bitbake about the PN-PV format of PROVIDES which is breaking the separation between bitbake and the metadata. We can't win :(. Nobody that I know of is using or relying on this functionality so perhaps we should just remove it instead which is what this patch does. Opinions?

bitbake.conf: Add SDKPKGSUFFIX to hash whitelist

2013-09-04T13:15:57+00:00

The gcc recipes reference this however we account for it in the work directory paths and we don't want recipes depending on the value changing. This avoids unecessary rebuilds when switching SDKs. (From OE-Core rev: 6cdcc543ce8f532a4f66246114241b43821a111e) Signed-off-by: Richard Purdie

Drop darwin8/darwin9 usage

2013-08-23T15:20:13+00:00

There were darwin8/darwin9 overrides spinkled in the code from times gone by. Lets settle on the darwin override and remove the others since its pointless duplication. We always inject darwin into OVERRIDES if needed in the darwin8/9 cases. (From OE-Core rev: 8d5e6eed7802a6056f9eaa50a85e3eee00fe2742) Signed-off-by: Richard Purdie

bitbake.conf: Work around dev symlink problems on darwin

2013-08-23T15:20:13+00:00

On darwin, we have: libxxx.dylib -> libxxx.Y.dylib compared to Linux which has: libxxx.so -> libxxx.so.Y Our ordering of PACKAGES with -dev first and then ${PN} makes it impossible to match the files correctly using simple globbing. This makes darwin targets completely broken since both the libs and the dev symlinks end up in ${PN}-dev. Whilst this commit is a hack, it at least puts the files into ${PN} and allows the builds to be used. Symlinks don't take up much space so this isn't the end of the world. I'm open to better solutions to this. (From OE-Core rev: 51c3dbe2df45096bbd7866adabb08e114952ff13) Signed-off-by: Richard Purdie

bitbake.conf/classes/gcc: Don't hardcode -nativesdk

2013-08-23T15:20:12+00:00

Hardcoding -nativesdk as the sdk package architecture is inflexible. We may have multiple different target OS and we need a way to be able to separate them. Turning this into a configurable value allows the flexibility we need to build different SDKMACHINEs with different OS targets. The commit should have no behaviour change, just makes things more configurable. (From OE-Core rev: a2110e86b98d646e136de9ec6b8e668079b0d4f4) Signed-off-by: Richard Purdie

gettext: Improve USE_NLS handling for nativesdk/crosssdk/cross-canadian

2013-08-23T15:20:11+00:00

The gettext handling of USE_NLS has become a bit tricky to understand, or alter from the SDK context. This patch introduces a SDKUSE_NLS which can be set to configure a given SDK/ADT to use NLS or not. This is independent of the target system NLS usage. The code in gettext.bbclass is therefore simplified and the classes themselves now set USE_NLS to appropriate values. No NLS is used for native, cross and crosssdk since it is never used there and would just increase build time.

package_rpm.bbclass: NO_RECOMMENDATIONS support

2013-08-22T17:30:00+00:00

Add NO_RECOMMENDATIONS support. A way to disable all recommended packages from being installed. This will help shrink the size of the resulting filesystem. Add documentation on NO_RECOMMENDATIONS and BAD_RECOMMENDATIONS. Note, using NO_RECOMMENDATIONS has side effects such that kernel-modules may not have been installed. A user will need to manually add to their image any kernel-modules required to be on the image for functionality.
