Even though libbpf's versioning script for the linker (libbpf.map)
is pointing to 0.0.2, the BPF_EXTRAVERSION in the Makefile has
not been updated along with it and is therefore still on 0.0.1.
While fixing up, I also noticed that the generated shared object
versioning information is missing, typical convention is to have
a linker name (libbpf.so), soname (libbpf.so.0) and real name
(libbpf.so.0.0.2) for library management. This is based upon the
LIBBPF_VERSION as well.
The build will then produce the following bpf libraries:
# ll libbpf*
libbpf.a
libbpf.so -> libbpf.so.0.0.2
libbpf.so.0 -> libbpf.so.0.0.2
libbpf.so.0.0.2
# readelf -d libbpf.so.0.0.2 | grep SONAME
0x000000000000000e (SONAME) Library soname: [libbpf.so.0]
And install them accordingly:
# rm -rf /tmp/bld; mkdir /tmp/bld; make -j$(nproc) O=/tmp/bld install
Auto-detecting system features:
... libelf: [ on ]
... bpf: [ on ]
