A fast and flexible C++ library for working with OpenStreetMap data.

NOTE: This is a beta version of the next-generation Osmium. For production use, see the Osmium version at https://github.com/joto/osmium .

There are a few applications that use the Osmium library in the examples directory. See the osmium-contrib repository for more example code.

Libosmium is developed on Linux, but also works on OSX and Windows (with some limitations).

Because Osmium uses many C++11 features you need a modern compiler and standard C++ library. Osmium needs at least GCC 4.8 or clang (LLVM) 3.2. (Some parts may work with older versions.)

Different parts of Osmium (and the applications built on top of it) need different libraries. You DO NOT NEED to install all of them, just install those you need for the programs you need.

boost-iterator, boost-regex

    openSUSE: zlib-devel

bz2lib (for bzip2 support when reading/writing XML)

GDAL (for OGR support)
    http://gdal.org/

You need to either install the packages for your distribution or install those libraries from source. Most libraries should be available in all distributions.

• include: C/C++ include files. All of Osmium is in those header files which are needed for building Osmium applications.

• examples: Osmium example applications.

• test: Tests (see below).

• doc: This is where the documentation will be build, call "make doc" to build.

Osmium is a header-only library, so there is nothing to build for the library itself.

Call "make doc" in the top-level directory to build the Osmium C++ docs.

Call "make install" to install the include files and documentation.

Call "make clean" to clean up.

To build the examples go to the "examples" directory and type "make".

For Mac users: If you have clang 3.2 or newer, use the system compiler. If not you have to build the compiler yourself. See the instructions on http://clang.llvm.org/ .

Preliminary support for cmake is provided. You can use this instead of "make":

mkdir build
cd build
cmake ..
make

There are a few unit tests using the Catch unit test framework in the "test" directory. Many more tests are needed, any help appreciated.

For Catch only one header file is needed which is included (test/include/catch.hpp).

Run "make test" from the main directory or go to the "test" directory and type

./run_tests.sh

to compile and run the tests. You can run a single test by calling

./run_test.sh TESTFILE

for instance:

./run_test.sh t/basic/test_node.cpp

In addition there are some test based on the OSM Test Data Repository at http://osmcode.org/osm-testdata/ . Go into the test/osm-testdata directory and type 'make' to run them all.
