docs/manual: fix bash export syntax in example code

2015-11-11T22:12:30+00:00

To export a variable in .bashrc we shouldn't put a '$' at the beginning of the line, and there must be a '=' between key and value. Signed-off-by: Luca Ceresoli Signed-off-by: Thomas Petazzoni

docs/manual: document $(FOO_PKGDIR)

2015-11-04T23:01:23+00:00

In the manual, add a note that packages can use $(FOO_PKGDIR) to get the path to the directory containg the .mk and Config.in files, if they need it to e.g. copy files from there, like startup scripts, systemd units or any other resource.

docs/manual: do not override BR2_EXTERNAL

2015-11-03T22:42:24+00:00

Currently, we forcibly override BR2_EXTERNAL when building the manual, so as to avoid referring to packages therein from the manual. However, when generating the lists of packages, we limit ourselves to scanning for packages in (Buildroot's) TOPDIR and never search in BR2_EXTERNAL. So, we do not really need to override BR2_EXTERNAL when generating the manual to achieve the same result. Furthermore, we're only looking for packages that are defined in the sub-menu "Target packages", and never anywhere else, and especially not in the sub-menu "User-provided options". Finally, we're soon to completely eliminate use of BR2_EXTERNAL in Kconfig altogether, so that would no longer have any impact anyway. So, just leave BR2_EXTERNAL alone when generating the manual.

core/pkg-generic: allow packages to exclude files when extracting

2015-11-03T21:20:30+00:00

Currently, packages that need to exclude parts of the archives when extracting (e.g. to gain space), like gcc or toolchain-external, have to provide custom extract commands, just for the sake of adding a bunch of --exclude directives when calling tar. Add a new variable that packages may set, to provide a space-separated list of patterns to exclude. Signed-off-by: "Yann E.

Revert "manual: Add notes about GitHub and hashes"

2015-10-18T15:59:40+00:00

This note is no longer needed, so remove it. Tarballs generated by GitHub are always the same, so hashes can be checked. This reverts commit 9474cc2594c8643301164500ce6eb62546da2b8f.

ccache: allow for BR2_CCACHE_DIR environment override

2015-10-17T14:32:41+00:00

Allow the BR2_CCACHE_DIR .config option to be overriden by the BR2_CCACHE_DIR env variable. This is useful for big projects where in some cases the developers home directory might be a NFS mount (slow) and real production builds aren't. Update documentation accordingly as well.

ccache: support changing the output directory

2015-10-04T16:22:21+00:00

When building in a different output directory than the original build, there will currently be a lot of ccache misses because in many cases there is some -I/... absolute path in the compilation. Ccache has an option CCACHE_BASEDIR to substitute absolute paths with relative paths, so they wil be the same in the hash (and in the output). Since there are some disadvantages to this path rewriting, it is made optional as BR2_CCACHE_USE_BASEDIR. It defaults to y because the usefulness of ccache is severely reduced without this option. In addition to CCACHE_BASEDIR, we also substitute away the occurences of $(HOST_DIR) in the calculation of the compiler hash. This is done regardless of the setting of BR2_CCACHE_USE_BASEDIR because it's quite harmless. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Peter Korsgaard
