Would it be feasible/advantageous for xpressive to have an installation procedure a'la regex to build a whole series of .lib libraries?
That seems to speed up builds quite a bit.
Everything is a template. What should be exported from the lib? It would be impossible for static regexes. For dynamic regexes, it would be possible to put sregex_compiler, cregex_compiler, and the wide char variants into a separate lib, but you're the first to ask for it, and I haven't felt the need. In fact, some prefer header only libs because they're easier to work with. A significant fraction of the problems reported with boost.regex have to do with problems linking to the separate lib. I'm not sure I want to spend my time debugging other people's build configurations. :-P My suggestion would be to have one cpp file in your project that exports the following function: sregex sregex_compile( std::string const &pat , regex_constants::syntax_option_type flags) { return sregex::compile(pat, flags); } In this file and this file only, you include xpressive_dynamic.hpp. (You can export other functions for other basic_regex instantiations.) In files where you use regexes, you can include basic_regex.hpp, regex_algorithms.hpp, match_results.hpp, and sub_match.hpp. Wherever you need static regexes, you should include xpressive_static.hpp. This should give you all the benefit of separate compilation.
