package, toolchain: remove BR2_TOOLCHAIN_HAS_GCC_BUG_* options

2016-01-30T10:02:30+00:00

Quite some time ago, we added the options BR2_TOOLCHAIN_HAS_GCC_BUG_58595 and BR2_TOOLCHAIN_HAS_GCC_BUG_58854 to indicate if the toolchain was affected by those gcc bugs, which were causing build failure with a number of packages. With the recent change in the external toolchain logic to provide only the latest version of each toolchain "family", all the toolchains which were affected by those issues disappeared from Buildroot. Those options are no longer being selected anywhere, and being blind options, it means their value is always going to be "disabled". Conquently, this commit removes those options completely, and updates all the packages where they were used. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

package/liburcu: introduce BR2_PACKAGE_LIBURCU_ARCH_SUPPORTS symbol

liburcu: disable build with gcc-4.8.x on ARM

2014-03-23T22:17:56+00:00

Because of a gcc bug [1], liburcu checks for compiler version [2] and stops the build prematurely if gcc-4.8.[0-2] is detected for ARM. However a bug fix exists [3] and may be backported by ARM toolchain providers; that's what is done in Buildroot [4] or Linaro [5]. So, this change: - add a patch in liburcu to allow build with ARM gcc-4.8.2; - adds a new hidden symbol to reflect the toolchain status with regard to this bug [1]; - and controls liburcu visibility. However, a limitation of this is when the user is using a custom toolchain; that's why the bug details have been added in the liburcu help message.

Config.in files: add missing dependencies to toolchain option comments

2013-11-10T22:59:57+00:00

When a package A depends on config option B and toolchain option C, then the comment that is given when C is not fulfilled should also depend on B. For example: config BR2_PACKAGE_A depends on BR2_B depends on BR2_LARGEFILE depends on BR2_WCHAR comment "A needs a toolchain w/ largefile, wchar" depends on !BR2_LARGEFILE || !BR2_WCHAR This comment should actually be: comment "A needs a toolchain w/ largefile, wchar" depends on BR2_B depends on !BR2_LARGEFILE || !BR2_WCHAR or if possible (typically when B is a package config option declared in that same Config.in file): if BR2_B comment "A needs a toolchain w/ largefile, wchar" depends on !BR2_LARGEFILE || !BR2_WCHAR [other config options depending on B] endif Otherwise, the comment would be visible even though the other dependencies are not met. This patch adds such missing dependencies, and changes existing such dependencies from depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC to depends on BR2_BASE_DEP depends on !BR2_TOOLCHAIN_USES_GLIBC so that (positive) base dependencies are separate from the (negative) toolchain dependencies. This strategy makes it easier to write such comments (because one can simply copy the base dependency from the actual package config option), but also avoids complex and long boolean expressions.
