Bug#927739: FTBFS: undefined reference to `yylex'

[Sebastian Dröge <slomo@debian.org>]

Source: libkate
Version: 0.4.1-9
Severity: serious

Hi,

Something seems to have changed with flex, which causes the package to now
fail to build:

/bin/bash ../libtool  --tag=CC  --silent --mode=link gcc -Wall -W    -I/usr/include/libpng16 -g -O2 -fdebug-prefix-map=/home/slomo/tmp/foo/libkate-0.4.1=. -fstack-protector-strong -Wformat -Werror=format-security  -Wl,-z,relro -Wl,-z,now -o kateenc kateenc-kateenc.o kateenc-kate_lexer.o kateenc-kate_parser.o kateenc-kpng.o ../lib/liboggkate.la ../lib/libkate.la -logg -lpng16 -lz -lfl 
/usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/8/../../../x86_64-linux-gnu/libfl.so: undefined reference to `yylex'
collect2: error: ld returned 1 exit status


Thanks!
