* package/libunwind: link to libgcc_s, not libgccYann E. MORIN2014-11-173-0/+41
| | | | | | | | | | | | | Backport a fix from upstream to link against libgcc_s instead of libgcc.

* libunwind: add patch to fix behavior for ARM < v6Thomas Petazzoni2014-05-143-0/+57
| | | | | | | | | | | | | | | | | | Since libatomic_ops does not implement real atomic operations for ARMv4 and ARMv5, libunwind must define AO_REQUIRE_CAS do indicate it requires compare-and-swap operations, even if not available as real atomic operations for the current architecture. In this case, libatomic_ops will rely on emulated atomic operations, which also require linking against libatomic_ops, which was until now not done by libunwind. This fixes the mysterious ltrace build issue: http://autobuild.buildroot.org/results/e1b/e1b330abfa2d80f3f30bc3359428ea429c690eb8/ Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>

* Config.in files: add missing dependencies to toolchain option commentsThomas De Schampheleire2013-11-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
