Description Phil Oester 2013-08-06 00:31:52 UTC
Attempting to compile netfilter project "nftables" code causes the below errors:

  CC            src/scanner.c
<stdout>: In function ‘nft_lex’:
<stdout>:1789:23: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
<stdout>: In function ‘nft__scan_bytes’:
<stdout>:3659:17: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]

Because the version of flex shipped with F19 needs this upstream patch:


Applying this patch solves the problem, and nftables can be compiled successfully.
