Hi
We're looking at optimizing some of the compile time performance in Boost.Fusion. I'm looking for any experience in Boost of measuring build times / compile time cost, how to structure tests that cover it etc. Does Boost.Build provide any support for measuring compile time for example?
Actually it does. In fact, I added the facility that allows it to bjam long ago. I think it might be visible in the XML output, but I've forgotten more than I ever knew about bjam/BB, so you'd have to ask someone else.
I'm aware there's a Perl script by Steven Watanabe that measures template instantiations if I understand correctly. Are there any other techniques that are being used that I should be aware of?
It's pretty simple just to use time g++ ...whatever... If you need to run windoze commands, you can just install cygwin and use its implementation of time. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
