Lex and YACC under C++ namespace

MTK358 · 04-21-2011, 08:31 PM

I'm making a shared library that contains a Lex/YACC parser. To keep the functions generated by Lex/YACC from conflicting with any names in a program linked to the library, I'd like to use namespaces.

The problem is that when I include namespace statements in the Lex input file, they come after some things and before others on the generated file, causing conflicts. Is I simply wrap the namespace statements around the generated file, it won't compile because the #include's are in the namespace.

What should I do?

'gcc' allows you to obtain post-processed file, so all the include files are already included and all the '#ifdef's are resolved.

It should be much easier to add namespace to a single "flat" file.
