Hi, building current master of https://git.netfilter.org/nftables i get a build error that i didn't see a few weeks ago. I thought I'd report it here. I bisected to identify this commit to be the start of build failures for me: commit 79195a8cc9e9d9cf2d17165bf07ac4cc9d55539f Author: Phil Sutter <phil@xxxxxx> Date: Thu Nov 24 14:17:17 2022 +0100 "xt: Rewrite unsupported compat expression dumping" This is the build error at above commit: CC xt.lo CC libparser_la-scanner.lo ../src/nftables/src/scanner.l: In function 'nft_lex': ../src/nftables/src/scanner.l:804:60: error: 'XT' undeclared (first use in this function); did you mean 'CT'? ../src/nftables/src/scanner.l:804:60: note: each undeclared identifier is reported only once for each function it appears in On 'master', the build error is different: CC libparser_la-scanner.lo ../src/nftables/src/scanner.l: In function 'nft_lex': ../src/nftables/src/scanner.l:625:10: error: 'VXLAN' undeclared (first use in this function); did you mean 'VLAN'? ../src/nftables/src/scanner.l:625:10: note: each undeclared identifier is reported only once for each function it appears in ../src/nftables/src/scanner.l:626:10: error: 'VNI' undeclared (first use in this function) ../src/nftables/src/scanner.l:628:10: error: 'GENEVE' undeclared (first use in this function) ../src/nftables/src/scanner.l:630:61: error: 'GRE' undeclared (first use in this function); did you mean 'GTE'? ../src/nftables/src/scanner.l:631:61: error: 'GRETAP' undeclared (first use in this function) ../src/nftables/src/scanner.l:812:60: error: 'XT' undeclared (first use in this function); did you mean 'CT'? ~N
