>            Reporter: Benjamin Bannier

> Mesos uses a pretty standard autotools setup for the build so that 
> {{libtool}} is used extensively to abstract away the aspects of library 
> creation (both compiling source files, and creating the libraries). For some 
> versions of {{libtool}} its invocation can add considerably to the overall 
> build time.
> Dolt provides a much more condensed implementation of {{libtool}}'s 
> functionality for modern platforms (<100 locs vs ~10 klocs), so that it can 
> run much faster. We should investigate whether activating dolt makes sense.
> I tested dolt under OS X 10.10.5. I first primed ccache and then rebuilt 
> mesos-related objects,
> {code}
> ./configure --disable-python --disable-java  # benchmark mostly C & C++ file 
> compile and link
> make check GTEST_FILTER=''                   # prime ccache
> make mostlyclean                             # remove most mesos objects and 
> libs
> make -jN check GTEST_FILTER=''               # rebuild
> {code}
