Merge lp:~zorba-coders/zorba/bug-1034582-flexlexerh into lp:zorba

[Chris Hillery]

Add "generation" of local copy of FlexLexer.h, to ensure it always stays in sync with the generated lexer .cpp file.

Why do you copy FlexLexer.h to the top-level src directory? Why isn't it copied to build/src/compiler/parser to mirror the pre-generated location?

[Paul J. Lucas (paul-lucas)]

Yep, it works on Mountain Lion using the stock flex.
