Is your php_lexer.c generated on your machine ? Could you compare it with the one from SVN? Maybe it's a problem with your flex.
well not quite sure what you mean. php_lexer.c gets generated right?
so what I did it
-make a backup of the currently (maybe wrong) php_lexer.c, to php_lexer.c.org
-rm php_lexer.c, and svn up , to restore it
the diff of those two return nothing.
amule-dev/trunk/src/webserver/src$ diff php_lexer.c php_lexer.c.org
btw my flex version
flex --version
flex 2.5.35
so anything else you need to know?!
