From: Tony Ambardar Date: Sun, 21 May 2023 09:14:37 +0000 (-0700) Subject: bpftools: update, split off bpftool and libbpf packages X-Git-Tag: v23.05.0-rc1~34 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f54bea12b6d5193509716b4c85bf2d342bbc0123;p=openwrt%2Fstaging%2Fhauke.git bpftools: update, split off bpftool and libbpf packages My original bpftools package made "variant" builds of bpftool and libbpf as a convenience, since both used the same local kernel sources with the same versioning. This is no longer the case, since the commit below switched to using an out-of-tree build mirror hosting repos for each. Replace bpftools with separate bpftool and libbpf packages, each simplified and correctly versioned. Also fix the broken libbpf ABI introduced in the same commit. Existing build .config files are not impacted. Fixes: 00cbf6f6ab1d ("bpftools: update to standalone bpftools + libbpf, use the latest version") Signed-off-by: Tony Ambardar (cherry picked from commit afe1bf11f2539f75e30ab3206891dbe6f8c43bd5) Signed-off-by: Daniel Golle --- diff --git a/package/libs/libbpf/Makefile b/package/libs/libbpf/Makefile new file mode 100644 index 0000000000..ee7666f734 --- /dev/null +++ b/package/libs/libbpf/Makefile @@ -0,0 +1,75 @@ +# +# Copyright (C) 2020-2023 Tony Ambardar +# +# This is free software, licensed under the GNU General Public License v2. +# See /LICENSE for more information. +# + +include $(TOPDIR)/rules.mk + +PKG_NAME:=libbpf +PKG_VERSION:=1.2.0 +PKG_RELEASE:=1 + +PKG_SOURCE_URL:=https://github.com/libbpf/libbpf +PKG_SOURCE_PROTO:=git +PKG_SOURCE_VERSION:=fbd60dbff51c870f5e80a17c4f2fd639eb80af90 +PKG_MIRROR_HASH:=80a80dfba71576e017b596fb28068e2a92de629e426f063e4b37314c8d576336 +PKG_ABI_VERSION:=$(firstword $(subst .,$(space),$(PKG_VERSION))) + +PKG_MAINTAINER:=Tony Ambardar + +PKG_BUILD_FLAGS:=no-mips16 +PKG_BUILD_PARALLEL:=1 +PKG_INSTALL:=1 + +include $(INCLUDE_DIR)/package.mk +include $(INCLUDE_DIR)/nls.mk + +define Package/libbpf + SECTION:=libs + CATEGORY:=Libraries + TITLE:=libbpf -
