First, you should use Boost Trunk, it compiles quite noticeably faster. Second, look in the Spirit examples directly with Boost Trunk, in the QI subdirectory, the mini_c directory has an example of just that.
I cant use use boost trunk, in order to get faster compiles, since I have to use boost1.38/1.39. Also it looks like the grammar construction in the examples is different. I looked for a similar example in boost 1.39 since we use closures but none exists. Surely anyone who is using spirit and building on multiple platforms must be be affected with this bug ?

On gcc the compilation times are acceptable. However on AIX with v10.1 compiler, it fails to even compile. After 24hrs waiting, I gave up. Ok I realise that the grammer needs to split. Is there any _small_ examples out there, that demonstrates this technique for a beginner ? In my case I have one grammer and ~70 rules. Take the following rule: rule<ScannerT, string_closure::context_t> identifier ; identifier = lexeme_d [ (alnum_p || ch_p('_')) >> *(alnum_p || ch_p('_')) ] [ identifier.name = construct_<std::string>(arg1, arg2) ] ; What is the technique for converting it into a grammer, that is separately compiled ? Also how would I reference it again, without including the header file, from another rule dotPath = ( str_p(".") >> +( str_p("/") >> identifier ) ) [ dotPath.name = construct_<std::string>(arg1, arg2) ] ; Any help would greatly appreciated.
