Description elofu17 2018-09-18 10:43:52 UTC
Not a bug, but big annoyance:

Sometime in the past 3 months, boost-libs have started depending on llvm60.

Is this dep *really* needed?
Due to this, my total compile time has drastically increased. :-/

llvm60 itself takes a loooong time to compile, plus the time for all its deps. Multiply this time by three (I'm using poudirere for building packages for three different FreeBSD versions) and half a day has passed before the builder has finished. :-)

If the dep can be removed, please make efforts to do so.

Fix Summary and assign.  However, I doubt that this will happen.  The ports default compiler for 11.x and 12.x is llvm60.
Comment 2 Jan Beich freebsd_committer 2018-09-18 11:55:22 UTC
Upgrade to FreeBSD 11.2 or 12.0 if you don't want llvm60. In-base Clang/libc++ 3.4 on FreeBSD 10.4 doesn't support C++14 but building with -std=c++14 (or -std=gnu++14) is required in order for Boost to be usable in C++14 consumers e.g.,

    databases/clickhouse
    databases/mongodb34
    databases/mongodb36
    editors/jucipp
    math/cadabra2
    multimedia/mkvtoolnix
    science/libgeodecomp
    sysutils/osquery
    www/osrm-backend

If you really want to stick to FreeBSD 10.4 beware that I'm planning to drop support after EOL on 2018-10-31.

Once FreeBSD 10.4 and 11.1 support is gone ports/ can enjoy C++17 everywhere except some architectures stuck on GCC: sparc64, powerpc*, mips*, riscv*. Very few ports will depend on devel/llvm60 (or newer) e.g., graphics/mesa-dri needs libLLVM for Gallium, www/firefox needs libclang to generate Rust bindings for C/C++.
