2016-12-04core: add a kconfig option to require an UTF8 locale on the hostYann E. MORIN

2016-10-16core: do not hard-code inclusion of br2-external in KconfigYann E. MORIN
Move the inclusion of br2-external's Config.in to the generated kconfig snippet. This will ultimately allow us to use more than one br2-external tree. Offload the "User-provided options" menu to the generated Kconfig snippet. We can also move the definition of the Kconfig-version of BR2_EXTERNAL into this snippet. We introduce an extra check that was not present in the previous code, to check that we do have permission on that directory. Prevciously, it was handled as a side effect of not being able to cd into there, but it is cleaner to check it expressly. Signed-off-by: "Yann E.

2016-10-15Remove BR2_DEPRECATEDArnout Vandecappelle
The BR2_DEPRECATED logic is a lot less useful than the legacy handling, because the symbols just disappears without warning to the user. For example, we had a few defconfigs that were using deprecated symbols (which were not actually used because BR2_DEPRECATED wasn't set) so these didn't build the expected code anymore. Also, the idea behind BR2_DEPRECATED is that you can easily revive it again if there is interest. However, it is relatively easy to revert the removal of a package as well. The deprecation is also more effort because it has to be removed twice: once when deprecating, and once when really removing. It doesn't make sense to add a legacy entry for BR2_DEPRECATED. Users who actually used it will get legacy warnings instead. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

2015-10-04ccache: support changing the output directoryArnout Vandecappelle
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.

2014-12-12Build shared libraries only as the defaultThomas Petazzoni
Now that we have more options in terms of static/shared libraries, switch from the existing default of building both shared and static libraries to building shared libraries only (of course only on platforms that support shared libraries). Building both shared and static takes time (since the shared objects must be built with -fPIC, while static objects are generally built without, as -fPIC has some performance impact) and consumes a little bit more disk space. For example, a static+shared build of libglib2 takes 1 minutes and 59 seconds, with a final build directory of 96 MB. A shared-only build of libglib2 takes only 1 minutes and 31 seconds (almost a 25% reduction of the build time), and the final build directory weights 89 MB (a reduction of almost 8%). So, switching to a shared library only build brings some useful build time and build size benefits. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: "Yann E.

2014-12-12Turn the static lib option into a choice with more optionsThomas Petazzoni
This commit turns the single static option into a choice, which offers various possibilities: 1. Build and use static libraries only; 2. Build both shared and static libraries, but use shared libraries; 3. Build and use shared libraries only. On most platforms, (2) is currently the default, and kept as the default in this commit. Of course, on certain platforms (Blackfin, m68k), only option (1) will be available. In addition to the introduction of the Config.in options, this commit also: * Removes the 'select BR2_STATIC_LIBS' from 'BR2_BINFMT_FLAT', since with the use of a choice, we are guaranteed that BR2_STATIC_LIBS will be selected when the binary format is BR2_BINFMT_FLAT, since BR2_STATIC_LIBS will be the only possible solution in the choice. * Changes package/Makefile.in to use the proper --{enable,disable}-{shared,static} options for autotools packages.

2014-12-11Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBSThomas Petazzoni
Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed from "prefer static libraries when possible" to "use only static libraries". The former semantic didn't make much sense, since the user had absolutely no control/idea of which package would use static libraries, and which packages would not. Therefore, for quite some time, we have been starting to enforce that BR2_PREFER_STATIC_LIB should really build everything with static libraries. As a consequence, this patch renames BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS, and adjust the Config.in option accordingly. This also helps preparing the addition of other options to select shared, shared+static or just static. Note that we have verified that this commit can be reproduced by simply doing a global rename of BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

2014-12-11Add option for paranoid unsafe path checkingThomas Petazzoni
This commit adds a Config.in option to the "Build options" submenu to enable paranoid checking of unsafe paths. This mechanism is added as an option so that when we'll enable it in the autobuilders, people trying to reproduce the build failures will be able to do so by just downloading the configuration file. If instead we were leaving this feature as an environment variable, everyone would have to remember to pass this environment variable to reproduce build issues. And certain build issues triggered by paranoid unsafe patch checking may not be visible in the build output, for example when they happen during the execution of configure scripts. Since this option is fairly advanced, a new submenu inside "Build options" is created, for Advanced options. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: "Yann E.
