* package: remove scripts listed in <pkg>_CONFIG_SCRIPTS from targetThomas Petazzoni2013-02-081-1/+6
| | | | | | | | | | The <foo>-config scripts are useless on the target, since they are only needed for development, so we remove them automatically.

* package: rename <pkg>_CONFIG_FIXUP to <pkg>_CONFIG_SCRIPTSThomas Petazzoni2013-02-081-8/+9
| | | | | | | | | | | | | | | | | | | | | | This commit renames the newly introduced <pkg>_CONFIG_FIXUP variable to <pkg>_CONFIG_SCRIPTS, for two reasons: * <pkg>_CONFIG_SCRIPTS will not only "fixup" the scripts in $(STAGING_DIR)/usr/bin, but also remove them from $(TARGET_DIR)/usr/bin. So it is not only about doing a "fixup". * On the principle, it is strange that the variable carries an indication of the action that will take place on those files. It should rather be named to say "Here are the <foo>-config scripts", and let the package infrastructure decide if it should fix them up, remove them, etc. This commit also updates the documentation accordingly.

* docs/manual: slightly reword the solutions to customize rootfsThomas Petazzoni2013-02-081-11/+18
| | | | | | | | | | | | | | | | | The order of the solutions to customize the root filesystem is changed: we now mention the post-build script mechanism *before* the custom root filesystem skeleton mechanism, because the former is preferred over the latter. In addition to this, we give a few more details about direct customization of the root filesystem in output/target, and about the custom target skeleton solution.

* Make savedefconfig save to a configured file.Arnout Vandecappelle (Essensium/Mind)2013-02-051-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Store BR2_DEFCONFIG in .config, and use it to update the original input defconfig file after updating the configuration. When a config is created by using the BR2_DEFCONFIG=... option, this is saved in the .config file; later runs of savedefconfig will update that same location. It is also possible to configure this place in the interactive configuration. The BR2_DEFCONFIG value itself is not saved into the generated defconfig, since Kconfig considers it at its default. This is intentional, to avoid hard-coding an absolute path in the defconfig. It will anyway be set again when the defconfig is used with the 'make BR2_DEFCONFIG=... defconfig' command. As a side-effect of this change, the *config options have been moved out of the BR2_HAVE_DOT_CONFIG condition. This doesn't make any functional difference, because the .config is still not read for the *config targets. However, the defconfig and savedefconfig targets do need to include .config now, which makes them slightly slower.

* pkg-infra: add <pkg>_CONFIG_FIXUP to fix *-config filesStefan Fröberg2013-02-041-27/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch will add <pkg>_CONFIG_FIXUP variable to buildroot infra. It's purpose is to inform buildroot that the package in question contains some $(STAGING_DIR)/usr/bin/*-config files and that we want to automatically fix prefixes of such files. It is often the case that many packages call these files during their configuration step to determine 3rd party library package locations and any flags needed to link against them. For example: Some package might try to check the existense and linking flags of NSPR package by calling $(STAGING_DIR)/usr/bin/nspr-config --prefix. Without this fix. NSPR would return /usr/ as it's prefix which is wrong when cross-compiling. Correct would be $(STAGING_DIR)/usr. All packages that have <pkg>_INSTALL_STAGING = YES defined and also install some config file(s) into $(STAGING_DIR)/usr/bin must hereafter also define <pkg>_CONFIG_FIXUP with the correspondig filename(s). For example: DIVINE_CONFIG_FIXUP = divine-config or for multiple files: IMAGEMAGICK_CONFIG_FIXUP = Magick-config Wand-config Signed-off-by: Stefan Fröberg <stefan.froberg@petroprogram.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

* Makefile: don't export O to the environmentPeter Korsgaard2013-01-141-1/+1
| | | | | | | | Several projects use the kernel style O=<dir> syntax to build out of tree, and atleast uClibc doesn't check that it was explictly passed on the command line, so setting it in the environment breaks the build. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* Makefile: export a few variables to help support scriptsYann E. MORIN2013-01-131-0/+7
| | | | | | | | | | | | | | | | | | | | | | | Support scripts (in support/) may need to parse the .config file, so give them an easy access to it, by exporting BUILDROOT_CONFIG with the fully- qualified path to .config. Also, post-build scripts may need to reference a few locations, so export those, too. Note: we export both O and BASE_DIR. Although they are the same, BASE_DIR is used internally, while O is used on the command line, which makes it a bit ambiguous to know which to use. As users use O= on the command line, they will probably tend to use that in their post-build scripts. Update doc accordingly. [Peter: fixed typo] Signed-off-by: "Yann E.

* docs/manual: add details on toolchain configurationThomas Petazzoni2012-12-295-204/+277
| | | | | | | | | | | | | | | | | | | | | | This commit adds a new section Working with Buildroot -> Details in configuration -> Cross-compilation toolchain that gives a lot of details about our three toolchain backends. It takes some elements that were previously later in the manual in "Embedded basics" and in "External toolchain" and combines them with more details about internal backend and Crosstool-NG backend. The "Embedded basics" section becomes empty and is therefore removed. A few elements have been lost in the process, but they were considered to not be really useful, especially located so far in the manual.

* docs/manual: add a new 'Details on Buildroot configuration' sectionThomas Petazzoni2012-12-292-0/+153
| | | | | | | | | | | | | | | | | | | | | | As discussed with Samuel Martin, there are a few questions about some Buildroot configuration aspects that come very often on the IRC channel and on the mailing-list. Topics such as the /dev management and init systems are often raised. Therefore, this patch adds a new section that provides details about the Buildroot configuration possibilities. It does not aim at replacing the help text of each configuration option, but rather to complement them by providing more background. Having those informations in the manual will also make it easier for us to point newcomers to the right place in the documentation when they have questions. Note that this section will replace the "Embedded basics" section that comes way too late in the manual. This is done in a followup commit.
