From bde0250f069d80a6f823766566d9b146d7559dce Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 26 Oct 2016 21:12:03 +0200 Subject: [PATCH] kvm-unit-tests: add gcc version dependencies On x86 (both i386 and x86_64), the kvm-unit-tests code uses __builtin_reachable, which appeared in gcc 4.5. This commit adds the relevant dependencies to kvm-unit-tests: - on i386, we need gcc 4.5 as the target compiler - on x86-64, we need gcc 4.5 as the host compiler, because we use the host compiler to build kvm-unit-tests for this architecture Fixes: http://autobuild.buildroot.net/results/21340a7e6494e23adb2fe8dc6253ab220c380fec/ Signed-off-by: Thomas Petazzoni --- package/kvm-unit-tests/Config.in | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/package/kvm-unit-tests/Config.in b/package/kvm-unit-tests/Config.in index d72c734e78..f704a8e0c3 100644 --- a/package/kvm-unit-tests/Config.in +++ b/package/kvm-unit-tests/Config.in @@ -1,8 +1,14 @@ config BR2_PACKAGE_KVM_UNIT_TESTS bool "kvm-unit-tests" select BR2_HOSTARCH_NEEDS_IA32_COMPILER if BR2_x86_64=y - depends on BR2_arm || BR2_i386 || BR2_powerpc64 || \ - BR2_powerpc64le || BR2_x86_64 + # on i386 and x86-64, __builtin_reachable is used, so we need + # gcc 4.5 at least. on i386, we use the target gcc, while on + # x86-64 we use the host gcc (see .mk file for details) + depends on BR2_arm || \ + (BR2_i386 && BR2_TOOLCHAIN_GCC_AT_LEAST_4_5) || \ + BR2_powerpc64 || \ + BR2_powerpc64le || \ + (BR2_x86_64 && BR2_HOST_GCC_AT_LEAST_4_5) help kvm-unit-tests is a project as old as KVM.
