* Build shared libraries only as the defaultGravatar Thomas Petazzoni2014-12-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Turn the static lib option into a choice with more optionsGravatar Thomas Petazzoni2014-12-121-9/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBSGravatar Thomas Petazzoni2014-12-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Add option for paranoid unsafe path checkingGravatar Thomas Petazzoni2014-12-111-0/+20
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current default for BR2_PACKAGE_OVERRIDE_FILE points to: $(TOPDIR)/local.mk This works well for in-tree builds, but is not very useful for out-of-tree builds, when the Buildroot source tree may be shared for different concurrent builds. Also, it seems to be more sensible to have local.mk alognside the .config file. Hence, change the default for BR2_PACKAGE_OVERRIDE_FILE to point to: $(CONFIG_DIR)/local.mk Note that this does not change the current behaviour for in-tree builds, since in that case $(CONFIG_DIR) == $(TOPDIR).

SWIG outputs an XML file that contains a complete description of the structure of the API. In the second phase, the XML file is ingested by a Groovy (Java) program that then creates C++ code that forms the bridge to the scripting language (Python). The second phase is why we need java on the host.

| | | | | | | | | | | | | | | | | | | | | In order to keep better track of when a feature got deprecated, and hence when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is introduced. These symbols are automatically selected when BR2_DEPRECATED is selected, and thus are transparent to the user. A deprecated feature will no longer depend on BR2_DEPRECATED directly, but rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does not yet exist, it has to be created in Config.in. When removing a deprecated feature, one should also check whether this was the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which case the latter can be removed from Config.in. A followup patch will make sure the overview is added to the list of deprecated features in the manual, so that a buildroot core developer can easily determine which features to remove in a given development cycle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit allows the BR2_EXTERNAL directory to contain Config.in and Makefile code, which gets integrated into the Buildroot build logic: - Buildroot automatically includes the $BR2_EXTERNAL/Config.in in the top-level configuration menu. - Buildroot automatically includes the BR2_EXTERNAL/external.mk in the build logic, so it can for example be used to include other .mk files that define package recipes. This is typically intended to be used to create target packages in the BR2_EXTERNAL directory, but can also be used for bootloaders, host packages, or other custom make logic. We also add a dummy Config.in file in support/dummy-external/ to ensure that the source "$BR2_EXTERNAL/Config.in" line will point to an existing file even when BR2_EXTERNAL is not used by the user.

* core: introduce the BR2_EXTERNAL variableGravatar Thomas Petazzoni2013-12-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces the BR2_EXTERNAL environment variable, which will allow to keep Buildroot customization (board-specific configuration files or root filesystem overlays, package Config.in and makefiles, as well as defconfigs) outside of the Buildroot tree. This commit only introduces the variable itself, and ensures that it is available within Config.in options. This allows us to use $BR2_EXTERNAL in a 'source' statement in Config.in. Following patches extend the usage of BR2_EXTERNAL to other areas (packages and defconfigs). In details, this commit: * Introduces the BR2_EXTERNAL Kconfig option. This option has no prompt, and is therefore not visible to the user and also not stored in the .config file. It is automatically set to the value of the BR2_EXTERNAL environment variable. The only purpose of this BR2_EXTERNAL Kconfig option is to allow $BR2_EXTERNAL to be properly expanded when used inside Kconfig source statements. * Calculates the BR2_EXTERNAL value to use. If passed on the command line, then this value is taken in priority, and saved to a .br-external hidden file in the output directory. If not passed on the command line, then we read the .br-external file from the output directory. This allows the user to not pass the BR2_EXTERNAL value at each make invocation. If no BR2_EXTERNAL value is passed, we define it to support/dummy-external, so that the kconfig code finds an existing $(BR2_EXTERNAL)/package/Config.in file to include. * Passes the BR2_EXTERNAL into the *config environment, so that its value is found when parsing/evaluating Config.in files and .config values.

* core: add BR2_HOSTARCH_NEEDS_IA32_COMPILER optionGravatar Thomas Petazzoni2013-12-011-0/+6
| | | | | | | | | | | | | | | | Some bootloaders (such as Grub) need to be built for x86 (i.e IA32) even if the target architecture is x86-64. However, when the target architecture is x86-64, the cross-compiler generated by Buildroot is not able to generate 32 bits code. To solve this, we will rely on the host compiler being a x86 + x86-64 compiler. Therefore, this commit introduces the BR2_HOSTARCH_NEEDS_IA32_COMPILER option, which tells the dependency checking logic to verify that the host compiler is indeed capable of building x86 32 bits code.

* toolchain: refactor Stack Smashing Protection supportGravatar Thomas Petazzoni2013-09-151-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | This commit refactors how Stack Smashing Protection support is handled in Buildroot: *) It turns the BR2_TOOLCHAIN_BUILDROOT_USE_SSP option into an option that only enables the SSP support in uClibc, when using the internal toolchain backend. *) It adds an hidden BR2_TOOLCHAIN_HAS_SSP option that gets enabled when the toolchain has SSP support. Here we have the usual dance: glibc/eglibc in internal/external backend always select this option, in the case of uClibc/internal, it gets selected when BR2_TOOLCHAIN_BUILDROOT_USE_SSP is enabled, in the case of uClibc/external, there is a new configuration option that the user must select (or not) depending on whether the toolchain has SSP support. *) It adds a new options BR2_ENABLE_SSP in the "Build options" menu, to enable the usage of SSP support, by adding -fstack-protector-all to the CFLAGS.

* downloads: add basic CVS supportGravatar Gustavo Zacarias2013-09-131-0/+4
| | | | | | | | | | | | | | The support is for pserver mode anonymous CVS. source-check is based on login since many servers don't support or have ls/rls disabled. Usage is pretty straightforward. PKG_SITE defines the site hostname and remote directory. The module is defined by the bare package name. Version is date based.

* Remove BR2_HAVE_DEVFILESGravatar Thomas Petazzoni2013-07-041-8/+0
| | | | | | | | | | | | This finally removes the BR2_HAVE_DEVFILES option, that was used to install/keep development files on target. With the recent migration of the internal backend to the package infrastructure, we had anyway lost the ability to build gcc for the target, and install the uClibc development files on the target.

* rework patch modelGravatar Simon Dawson2013-03-191-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | At the Buildroot Developers Meeting (4-5 February 2013, in Brussels) a change to the patch logic was discussed. See http://elinux.org/Buildroot:DeveloperDaysFOSDEM2013 for details. In summary: * For patches stored in the package directory, if package/<pkg>/<version>/ does exist, apply package/<pkg>/<version>/*.patch, otherwise, apply package/<pkg>/*.patch * For patches stored in the global patches directory, if $(GLOBAL_PATCH_DIR)/<pkg>/<version>/ does exist, apply $(GLOBAL_PATCH_DIR)/<pkg>/<version>/*.patch, otherwise, apply $(GLOBAL_PATCH_DIR)/<pkg>/*.patch This patch adds the new BR2_GLOBAL_PATCH_DIR configuration item, and reworks the generic package infrastructure to implement the new patch logic.
