core/pkg-virtual: do not check they are neabled

2015-12-30T09:01:30+00:00

Virtual packages do not have a Kconfig symbol, so we must not check that they are enabled. Fixes: http://autobuild.buildroot.org/results/287/28713478cc6edf8e5d5c3e830fee86a42f0afa8d/ ... and numerous similar failures ... [Thomas: - use "$($(PKG)_IS_VIRTUAL)" != "YES" instead of ! "$($(PKG)_IS_VIRTUAL)" = "YES"] Signed-off-by: "Yann E. MORIN" Cc: Thomas Petazzoni Signed-off-by: Thomas Petazzoni

skeleton: New package

2015-07-14T16:08:23+00:00

Create a proper package for the skeleton. The main Makefile is modified to remove the skeleton support. The 'dirs' target, will create the $(TARGET_DIR). The file 'output/target/.root' doesn't exists anymore, as there's no Make rule to statisfy. The infrastructure are modified to filter host-skeleton. It's needed becauses the host-dependencies are derived from the dependencies of the target package where 'host-' is preprended to the depedency name. In the pkg-generic we add skeleton as a dependency to every package. The whole system/system.mk is now removed at the profit of package/skeleton/skeleton.mk [Thomas: - rebase on top of master and fix some minor conflicts - remove the 'select BR2_PACKAGE_SKELETON' in BR2_ROOTFS_SKELETON_DEFAULT and BR2_ROOTFS_SKELETON_CUSTOM, since anyway the skeleton package is always enabled. - fixup a few mistakes in the getty handling due to misnamed variables.] Signed-off-by: Maxime Hadjinlian Signed-off-by: Thomas Petazzoni

trivial: fix typo 'an host'

2014-07-24T20:29:54+00:00

In English, unlike in French, the 'h' in 'host' is pronounced, meaning that the article should be 'a' instead of 'an'. Signed-off-by: Thomas De Schampheleire Signed-off-by: Thomas Petazzoni

pkg-virtual: simplify definition of FOO_VERSION to 'virtual'

2014-06-14T17:10:08+00:00

As mentioned in the e-mail accompanying the introduction of the pkg-virtual infrastructure [1], the definition of FOO_VERSION is 'strange'. After the cleanup of single/double dollar signs in inner-generic-package, the special construction in pkg-virtual is no longer needed and can be simplified.

infra: consistently use double dollar signs inside inner-xxx-targets

2014-06-14T17:09:54+00:00

The inner-xxx-targets in the buildroot package infrastructures are evaluated using $(eval) which causes variable references to be a bit different than in regular make code. As we want most references to be expanded only at the time of the $(eval) we should not use standard references $(VAR) but rather use double dollar signs $$(VAR). This includes function references like $(call), $(subst), etc. The only exception is the reference to pkgdir/pkgname and numbered variables, which are parameters to the inner block: $(1), $(2), etc. This patch introduces consistent usage of double-dollar signs throughout the different inner-xxx-targets blocks. In some cases, this would potentially cause circular references, in particular when the value of HOST_FOO_VAR would be obtained from the corresponding FOO_VAR if HOST_FOO_VAR is not defined. In these cases, a test is added to check for a host package (the only case where such constructions are relevant; these are not circular). Benefits of these changes are: - behavior of variables is now again as expected. For example, setting $(2)_VERSION = virtual in pkg-virtual.mk will effectively work, while originally it would cause very odd results. - The output of 'make printvars' is now much more useful. This target shows the value of all variables, and the expression that led to that value. However, if the expression was coming from an inner-xxx-targets block, and was using single dollar signs, it would show in printvars as VAR = value (value) while if double dollar signs are used, it would effectively look like VAR = value (actual expression) as is intended. This improvement is for example effective for FOO_DL_VERSION, FOO_RAWNAME, FOO_SITE_METHOD and FOO_MAKE. The correctness of this patch has been verified using 'make printvars', 'make manual' and 'make legal-info' before and after applying this patch, and comparing the output.

packages: add infrastructure for virtual packages

2014-04-05T17:20:59+00:00

The virtual-package infrastructure allows to easily define a virtual package in a single line: $ cat package/some-virtual-package/some-virtual-package.mk $(eval $(virtual-package)) And that's all. :-) Thanks to Éric for his work on the manual, that prompted the idea for this virtual-package infrastructure! ;-) Signed-off-by: "Yann E.
