When attempting to build vpp against system libraries (dpdk, libbpf, etc) on Debian Bullseye I get the following error when building the af_xdp_plugin.so
Is the af_xdp plugin doing something unusual with libbpf? Thanks, Nick cd vpp/src mkdir mybuild cd mybuild cmake -GNinja -DVPP_USE_SYSTEM_DPDK=ON ninja -k0 [1/1] Linking C shared library lib/vpp_plugins/af_xdp_plugin.so FAILED: lib/vpp_plugins/af_xdp_plugin.so : && ccache /usr/bin/gcc-10 -fPIC -shared -o lib/vpp_plugins/af_xdp_plugin.so CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin_hsw.dir/input.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin_hsw.dir/output.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin_skx.dir/input.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin_skx.dir/output.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin_icl.dir/input.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin_icl.dir/output.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/api.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/cli.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/device.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/format.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/unformat.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/plugin.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/input.c.o CMakeFiles/plugins/af_xdp/CMakeFiles/af_xdp_plugin.dir/output.c.o -Wl,-rpath,:::::::::::::: -Wl,--gc-sections /usr/lib/x86_64-linux-gnu/libbpf.a /usr/lib/x86_64-linux-gnu/libelf.so /usr/lib/x86_64-linux-gnu/libz.so && : /usr/bin/ld: /usr/lib/x86_64-linux-gnu/libbpf.a(libbpf.o): warning: relocation against `stderr@@GLIBC_2.2.5' in read-only section `.text' /usr/bin/ld: /usr/lib/x86_64-linux-gnu/libbpf.a(libbpf.o): relocation R_X86_64_PC32 against symbol `stderr@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: bad value collect2: error: ld returned 1 exit status ninja: build stopped: cannot make progress due to previous errors.
