Hello, because of a major issue I've just downgraded flex to version 2.5.33 because 2.5.34 has at least one major issue: - lex [1] uses %a, %p etc. constructs to ajust the size of several internal parameters. According to the manual [2] flex should silently ignore those, but 2.5.34 issues not-fatal errors and, more important, creates broken output. You can see that with opt/libpcap which builds but breaks at runtime. regards Juergen [1] http://www.cs.uaf.edu/~cs631/lex-docs.txt [2] http://flex.sourceforge.net/manual/Lex-and-Posix.html#Lex-and-Posix -- Juergen Daubert | mailto:jue@jue.li Korb, Germany | http://jue.li/crux
