Hi, I trying to install nftables from source ask part of my Outreachy application tasks. I already installed libmnl and libnftnl successfully. The problem comes after the 'make' command while trying to compile nftables. I'm running Ubuntu 16.04 and following the steps described here: https://wiki.nftables.org/wiki-nftables/index.php/Building_and_installing_nftables_from_sources I removed the last commit of the nftables master branch: 8dee5e43ad4beb2b0a95e0bbf2b3972630c1b327 'netlink: Use nftnl_expr_fprintf() in netlink_dump_expr()', to avoid a compilation error because a dependency with a libnftnl's patch still pending to apply. But the following error is beyond my skills right now and maybe is just a detail that I'm missing and somebody can help me. Thanks in advance frank Here is the relevant make output: ... make[3]: Leaving directory '/home/vagrant/git/pablo/nftables/nftables/include/linux' make[3]: Entering directory '/home/vagrant/git/pablo/nftables/nftables/include' make[3]: Nothing to be done for 'all-am'. make[3]: Leaving directory '/home/vagrant/git/pablo/nftables/nftables/include' make[2]: Leaving directory '/home/vagrant/git/pablo/nftables/nftables/include' Making all in doc make[2]: Entering directory '/home/vagrant/git/pablo/nftables/nftables/doc' GEN nft.8 Usage: jw [<options>] <sgml_file> where <options> are: -f|--frontend <frontend>: Specify the frontend (source format) (default is docbook) -b|--backend <backend>: Specify the backend (destination format) (default is html) -c|--cat <file>: Specify an extra SGML open catalog -n|--nostd: Do not use the standard SGML open catalogs -d|--dsl <file>|default|none: Specify an alternate style sheet (default is to use the default stylesheet) -l|--dcl <file>: Specify an alternate SGML declaration (usual ones like xml.dcl get detected automatically) -s|--sgmlbase <path>: Change base directory for SGML distribution (usually /usr/share/sgml) -p|--parser <program>: Specify the parser if several are installed (jade or openjade) -o|--output <directory>: Set output directory -u|--nochunks: Output only one big file (overrides the stylesheet settings) -i|--include <section>: Specify a SGML marked section to include (should be marked as "ignore" in the SGML text) -w|--warning <warning_type>|list: Control warnings or display the allowed warning types -e|--errors <error_type>|list: Control errors or display the allowed error types -h|--help: Print this help message and exit -V <variable[=value]>: Set a variable -v|--version: Print the version and exit Makefile:539: recipe for target 'nft.8' failed make[2]: *** [nft.8] Error 1 make[2]: Leaving directory '/home/vagrant/git/pablo/nftables/nftables/doc' Makefile:397: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory '/home/vagrant/git/pablo/nftables/nftables' Makefile:338: recipe for target 'all' failed make: *** [all] Error 2 -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
