git clone --depth 1 https://github.com/libbpf/libbpf
cd src
sudo make install

[root@junqiang src]# make install
  INSTALL  bpf.h libbpf.h btf.h libbpf_common.h libbpf_legacy.h bpf_helpers.h bpf_helper_defs.h bpf_tracing.h bpf_endian.h bpf_core_read.h skel_internal.h libbpf_version.h usdt.bpf.h
  INSTALL  ./libbpf.pc
  INSTALL  ./libbpf.a ./libbpf.so ./libbpf.so.1 ./libbpf.so.1.0.0

 还有个方法：

[root@junqiang bpf]# pwd
/usr/src/kernels/4.19.100/tools/lib/bpf
[root@junqiang bpf]# make

最后把lib及头文件放到相应的位置
