Is there multithreaded compilation support? #139

Closed w4454962 closed 2 years ago

For example, it takes more than 1 minute to preprocess and compile a 10MB source file, which is really too slow

In my view performance has not been worked on very seriously in Wave - though @hkaiser will know better. "PRs welcome" as they say :)

I am curious about your phrasing, though - when you say "to preprocess and compile" what do you mean? Wave only does preprocessing.

Sorry, my wording is a little unclear. It refers to the time when the preprocessing macro is expanded

Thanks @jefftrull for digging this up. Indeed, setting BOOST_WAVE_SUPPORT_THREADING=0 should help a lot.

Thank you. The speed has been greatly improved after the modification.
