From c750dd4e5d03430148841d2d897e90dbe19ce172 Mon Sep 17 00:00:00 2001 From: Fabrice Fontaine Date: Thu, 24 Feb 2022 18:51:19 +0100 Subject: [PATCH] package/bpftool: add BR2_PACKAGE_BPFTOOL_ARCH_SUPPORTS bpftool uses its own local copy of libbpf so add BR2_PACKAGE_BPFTOOL_ARCH_SUPPORTS to avoid the following build failure on ARM: btf.c: In function 'btf_type_by_id': btf.c:461:14: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] if (type_id < btf->start_id) ^ bpf.c:62:4: error: #error __NR_bpf not defined. libbpf does not support your arch. # error __NR_bpf not defined. libbpf does not support your arch. ^ Fixes: - http://autobuild.buildroot.org/results/aae772f1cfb16516a57f310c4f022e80a2a8d65e Signed-off-by: Fabrice Fontaine Signed-off-by: Arnout Vandecappelle (Essensium/Mind) --- package/bpftool/Config.in | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/package/bpftool/Config.in b/package/bpftool/Config.in index e81d874343..a1ef3843e6 100644 --- a/package/bpftool/Config.in +++ b/package/bpftool/Config.in @@ -1,5 +1,15 @@ +config BR2_PACKAGE_BPFTOOL_ARCH_SUPPORTS + bool + # see libbpf/src/bpf.c + default y if BR2_arc + default y if BR2_aarch64 || BR2_aarch64_be + default y if BR2_i386 || BR2_x86_64 + default y if BR2_sparc || BR2_sparc64 + default y if BR2_s390x + config BR2_PACKAGE_BPFTOOL bool "bpftool" + depends on BR2_PACKAGE_BPFTOOL_ARCH_SUPPORTS depends on !BR2_nios2 # binutils depends on BR2_USE_WCHAR # binutils, elfutils depends on !BR2_STATIC_LIBS # elfutils @@ -13,6 +23,7 @@ config BR2_PACKAGE_BPFTOOL of eBPF programs and maps. comment "bpftool needs a uClibc or glibc toolchain w/ wchar, dynamic library, threads, headers >= 4.12" + depends on BR2_PACKAGE_BPFTOOL_ARCH_SUPPORTS depends on !BR2_nios2 depends on !BR2_USE_WCHAR || BR2_STATIC_LIBS \ || !BR2_TOOLCHAIN_HAS_THREADS \
