Now as I look at it again, it is not necessarily the flex version that is not correct, syslog-ng ships a generated cfg-lex.c file, and "linenum" variable is not something that -lfl exports but it is defined by cfg-lex.l (which is used to generate cfg-lex.c), as it seems you might have regenerated cfg-lex.c for some reason but it might be empty?
Please try to include the make output that generated cfg-lex.c and the contents of your cfg-lex.c is also interesting.
