This speeds up processings on the same dataset significantly by creating
a .level file that saves the level in which a node was contracted.
It removes the need for expensive recomputation of priorities and such.
Use with care! Running `osrm-extract` again will invalidate .level
files.
table plugins.
Make bearing range configurable by adding a comma-separated second part
to the bearing paramenter, like so:
b=<bearing:0-359>(,<range:0-180>)
If no range is supplied, it defaults to +/- 10 degrees.
New Travis CI integration - upgrades Linux builds to Ubuntu trusty, simplifies dependency installation because system packages are now available for most things.
This checks if `ccache` is available, and if so uses it.
The user can stil disable it via the ccache env variable, quoting:
disable (CCACHE_DISABLE) [boolean]
When true, ccache will just call the real compiler, bypassing the cache completely. The default is false.
At least Clang required `CCACHE_CPP2`.
The user does not have to set up anything, just to install ccache.
Of course, things like the cache's max size, its location and so on can
be configured.

By linking in the coordinate object file twice, we violate the ODR,
resulting in our program to not be "well-formed" in language lawyer
speak (hint: bad, very bad).
(How come no one noticed this all the time, this was introduced
somewhere between v4.5.0 and v4.6.0 from a quick look...)

Instead of including the `luabind.hpp` header that transitively includes
basically everything else, we now only include the appropriate header
for luabind's open function.
It is important that this function is declared in the header but the
definition comes from the luabind shared object (library), such that we
can detect linker errors, too.
By only including this header, we also no longer transitively include
the header for the `luaL_newstate` function, with we have to add
manually.
With these changes, detecting, compiling, linking and checking for
lua/luabind with cmake now works instantly, instead of the 3-4
seconds as it was before! Yay, progress!
We were stuck on the 4.5.0 tag from develop, since we searched for the
latest tag, but release tags are done on the master branch.
This commit rips out all the code for deriving the version on git tags.
Instead, we define major, minor, and patch versions in the CMakeLists
and then pass it on to:
- the `libosrm.pc` `pkg-config` file
- a `version.hpp` header that makes use of the preprocessor's string
concatenation to provide an easy way for generating version string
literals such as "v4.8.0".
That is, in the source code please now use the following defines:
#define OSRM_VERSION_MAJOR "@OSRM_VERSION_MAJOR@"
#define OSRM_VERSION_MINOR "@OSRM_VERSION_MINOR@"
#define OSRM_VERSION_PATCH "@OSRM_VERSION_PATCH@"
#define OSRM_VERSION "v" OSRM_VERSION_MAJOR "." OSRM_VERSION_MINOR "." OSRM_VERSION_PATCH
- remove profiling/coverage mix from debug build, as it is useless as of
now, re-enable this for a separate coverage build in the future
- use gcc's `-ggdb` and `-Og` flag (requires recent gcc) to provide
better debug information targeted for gdb and optimize what we can
- use `-fno-inline` and `-fno-omit-stack-pointer`, in order to be able
to jump around in gdb without functions being gone and keeping the
stack reference
This refines the last commit of parallelizing lto.
Discussion: this is ugly as hell, dispatching 1/ on the availability of
the `-flto` flag, then 2/ on the compiler since GCC allows `-flto=n`
whereas Clang for example does not.
I tried setting the CMake property `INTERPROCEDURAL_OPTIMIZATION`,
without any effect. All I could see was some lto related utilities in
the cmake debug output, but not in the actual compiler or linker
invocation.
This would eliminate the need for our hacks, with 1/ using an option
`WITH_LTO` setting `ON` by default, and based on this value setting the
`INTERPROCEDURAL_OPTIMIZATION` flag with CMake doing the actual work of
selecting the best LTO method on the target platform.
By the way, this also fixes a bug where we reset the `CMAKE_CXX_FLAGS`
to a variable that was never defined, resulting in setting the flags to
an empty string. Yay CMake, as usual.
