Benjamin Bannier updated MESOS-4271:
------------------------------------
Sprint: Mesosphere Sprint 26
> Consider replacing libtool with dolt to speed up build
> ------------------------------------------------------
>
> Key: MESOS-4271
> URL: https://issues.apache.org/jira/browse/MESOS-4271
> Project: Mesos
> Issue Type: Improvement
> Reporter: Benjamin Bannier
> Assignee: Benjamin Bannier
> Priority: Minor
> Labels: build
>
> 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}
