[one-users] Compilation problem

[Upendra Sharma]

Thanks Ruben,
I tried and it doesnt compile ... 
my results ..
$> flex -Vflex version 2.5.4$> flex host_parser.l "host_parser.l", line 37: unrecognized %option: header-file

thats odd ... have they removed header-file option in the newer version ???
Frankly, I was trying to add an extra "SimpleOption" in the configuration file so, simply out of precaution, I switched on the flag "parsers=yes". Later, I checked that the lex file is general enough to work for me without any change. So, currently, I have managed to get it working ... but wanted to check with you folks if there is something wrong in my setup ... and it seems there is something wrong :).
Please do let me know if there is a fix for this problem.
thanks,-upendra
PS:On a completely different note: a not-so-important concern: I was wondering why the nebula folks chose to write their own parser, and why not use the standard XML parser? Given that storing configuration info in XMLs is not unpopular (I guess its widely followed).
