C++14. Let's do this.

Reference: mapbox/windows-builds#78

@BergWerkGIS there's no flag for Visual Studio, is there? The default will be good enough?

Let's see how both Appveyor and Travis like this.

VS 2015 Update 2 is not yet available as RTM and will still take some time (cannot say how long) for all C++14 features to arrive.

Also, I haven't yet looked into this error:

C:\projects\osrm\src\engine\engine.cpp(90): error C2039: 'shared_lock': is not a member of 'boost'

https://ci.appveyor.com/project/DennisOSRM/osrm-backend/build/1.0.2564#L1705

Has anything related to boost changed in osrm-backend lately?

[daniel-j-h]

Yes 3075f6c

[daniel-j-h]

Disabled the OSX shared lib build. In addition to not finding libosrm, it had a single cucumber test failing: https://travis-ci.org/Project-OSRM/osrm-backend/jobs/108934582#L481

I could not reproduce it locally via

cucumber -p verify features/options/routed/invalid.feature

and all the other builds are fine, too.

[daniel-j-h]

Travis gives okay!

Disclaimer: requires C++14 compiler and stdlib. That is, gcc<=4.8 is out. Also clang<=3.4 is out since it would require -std=c++1y and is probably not mature enough.

Let's require gcc>=4.9, clang>=3.5 and re-write the docs to simply install the gcc 5.3 ppa for older Ubuntus. gcc 4.9 is in Debian Jessie, so we're fine there.

I got develop and this branch to compile locally with this change:

Also had to patch boost as it disables some c++11 and c++14 features for Visual Studio by default:

e.g.:

BOOST_NO_CXX11_CONSTEXPR

Uploaded an updated binary deps package.

Tests are failing as it seems that algorithm-test.exe and datastructure-tests.exe don't get generated anymore.

Lock types fix landed in #1994

Urg looks like the auto merging f-ed up in this case after rebasing. We run against gcc 5.0 and gcc 4.9 now, right?

[daniel-j-h]

Yes, packages are gcc-5 (which really is gcc 5.3) and gcc-4.9.

[daniel-j-h]

Rebased onto develop.

Please reopen the PR for master, develop is going away.
