Hi, After downloading snapshots for NFTABLES and LIBNFTNL for 20200314 I proceeded to compile both library and NFTABLES Library compiled with no errors. libnftnl installed in /usr/local/lib pi@raspberrypi:~/nftables-20200314 $ ls -lia /usr/local/lib/libnftnl.* 130735 -rwxr-xr-x 1 root root 974 Mar 15 10:55 /usr/local/lib/libnftnl.la 150748 lrwxrwxrwx 1 root root 18 Mar 15 10:55 /usr/local/lib/libnftnl.so -> libnftnl.so.11.2.0 150737 lrwxrwxrwx 1 root root 18 Mar 15 10:55 /usr/local/lib/libnftnl.so.11 -> libnftnl.so.11.2.0 130734 -rwxr-xr-x 1 root root 969712 Mar 15 10:55 /usr/local/lib/libnftnl.so.11.2.0 nftables gives this error when compiling with Make /usr/bin/ld: ./.libs/libnftables.so: undefined reference to `nftnl_flowtable_set_data@LIBNFTNL_13' /usr/bin/ld: ./.libs/libnftables.so: undefined reference to `nftnl_udata_nest_end@LIBNFTNL_14' /usr/bin/ld: ./.libs/libnftables.so: undefined reference to `nftnl_obj_set_data@LIBNFTNL_13' /usr/bin/ld: ./.libs/libnftables.so: undefined reference to `nftnl_flowtable_get_u64@LIBNFTNL_11' /usr/bin/ld: ./.libs/libnftables.so: undefined reference to `nftnl_flowtable_set_u64@LIBNFTNL_11' /usr/bin/ld: ./.libs/libnftables.so: undefined reference to `nftnl_udata_nest_start@LIBNFTNL_14' I have tried to point link under nftables-20200314/src/.libs to point to /usr/local/lib with ln -sf /usr/local/lib/libnftnl.so ./libnftables.so Errors then are the following after running Make /usr/bin/ld: main.o: in function `main': /home/pi/nftables-20200314/src/main.c:260: undefined reference to `nft_ctx_new' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:305: undefined reference to `nft_ctx_output_get_debug' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:276: undefined reference to `nft_ctx_set_dry_run' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:285: undefined reference to `nft_ctx_add_include_path' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:331: undefined reference to `nft_ctx_output_set_debug' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:367: undefined reference to `nft_ctx_output_set_flags' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:384: undefined reference to `nft_run_cmd_from_buffer' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:400: undefined reference to `nft_ctx_free' /usr/bin/ld: /home/pi/nftables-20200314/src/main.c:386: undefined reference to `nft_run_cmd_from_filename' /usr/bin/ld: cli.o: in function `cli_complete': /home/pi/nftables-20200314/src/cli.c:133: undefined reference to `nft_run_cmd_from_buffer' collect2: error: ld returned 1 exit status make[3]: *** [Makefile:644: nft] Error 1 make[3]: Leaving directory '/home/pi/nftables-20200314/src' make[2]: *** [Makefile:500: all] Error 2 make[2]: Leaving directory '/home/pi/nftables-20200314/src' make[1]: *** [Makefile:479: all-recursive] Error 1 make[1]: Leaving directory '/home/pi/nftables-20200314' make: *** [Makefile:388: all] Error 2 running RASPBIAN (buster) on raspberry 3B Please, tell me what combination of lib and user app should I compile.
