Subject Re: feature test framework issue
Date Fri, 08 Jul 2016 02:34:24 GMT
Thanks for pointing this.
I am not sure, but I could remember the current way is to compile to object files and then
linking together to a feature-test binary.

Besides, I think the current compile time is like 80% of linking + 20% of compiling objects.

code compiles all of the test cpp files each time, regardless of single file change or no
file change. This is too time-consuming given in the future there will be more and more cases.
