This is a mirror of bpf-next linux tree (https://kernel.googlesource.com/pub/scm/linux/kernel/git/bpf/bpf-next) bpf-next/tools/lib/bpf directory plus its supporting header files. The following files will by sync'ed with bpf-next repo: src/ <-> bpf-next/tools/lib/bpf/ include/uapi/linux/bpf_common.h <-> bpf-next/tools/include/uapi/linux/bpf_common.h include/uapi/linux/bpf.h <-> bpf-next/tools/include/uapi/linux/bpf.h include/uapi/linux/btf.h <-> bpf-next/tools/include/uapi/linux/btf.h include/uapi/linux/if_link.h <-> bpf-next/tools/include/uapi/linux/if_link.h include/uapi/linux/if_xdp.h <-> bpf-next/tools/include/uapi/linux/if_xdp.h include/uapi/linux/netlink.h <-> bpf-next/tools/include/uapi/linux/netlink.h include/tools/libc_compat.h <-> bpf-next/tools/include/tools/libc_compat.h Other header files at this repo (include/linux/*.h) are reduced versions of their counterpart files at bpf-next/tools/include/linux/*.h to make compilation successful. Build ===== libelf is an internal dependency of libbpf and thus it is required to link against and must be installed on the system for applications to work. pkg-config is used by default to find libelf, and the program called can be overridden with PKG_CONFIG. If using pkg-config at build time is not desired, it can be disabled by setting NO_PKG_CONFIG=1 when calling make. To build both static libbpf.a and shared libbpf.so: cd src make To build only static libbpf.a library in directory build/ and install them together with libbpf headers in a staging directory root/: cd src mkdir build root BUILD_STATIC_ONLY=y OBJDIR=build DESTDIR=root make install To build both static libbpf.a and shared libbpf.so against a custom libelf dependency installed in /build/root/ and install them together with libbpf headers in a build directory /build/root/: cd src PKG_CONFIG_PATH=/build/root/lib64/pkgconfig DESTDIR=/build/root make install
