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
|
|
|
|
To integrate libbpf into a project which uses Meson building system define
|
|
[wrap-git] file in `subprojects` folder.
|
|
To add libbpf dependency to the parent parent project, e.g. for
|
|
libbpf_static_dep:
|
|
|
|
libbpf_obj = subproject('libbpf', required : true)
|
|
libbpf_static_dep = libbpf_proj.get_variable('libbpf_static_dep')
|
|
|
|
To validate changes to meson.build
|
|
|
|
python3 meson.py build
|
|
ninja -C build/
|
|
|
|
To install headers, libs and pkgconfig
|
|
cd build
|
|
ninja install
|
|
