GEOS -- Geometry Engine, Open Source ==================================== Project homepage: http://geos.osgeo.org/ ## Build status | branch / CI | Debbie | Winnie | Dronie | Travis CI | GitLab CI | AppVeyor | |:--- |:--- |:--- |:--- |:--- |:--- |:--- | | svn-trunk | [](https://debbie.postgis.net/view/GEOS/job/GEOS_Trunk/) | [](https://debbie.postgis.net:444/view/GEOS/job/GEOS_matrix_trunk/) | [](https://drone.osgeo.org/geos/geos?branch=svn-trunk) | [](https://travis-ci.org/OSGeo/geos?branch=svn-trunk) | [](https://gitlab.com/geos/libgeos/commits/svn-trunk) | [](https://ci.appveyor.com/project/OSGeo/geos/branch/svn-trunk) | | svn-3.6 | [](https://debbie.postgis.net/view/GEOS/job/GEOS_Branch_3.6/) | [](https://debbie.postgis.net:444/view/GEOS/job/GEOS_matrix_branch_3.6/) | [](https://drone.osgeo.org/geos/geos?branch=svn-3.6) | [](https://travis-ci.org/OSGeo/geos?branch=svn-3.6) | [](https://gitlab.com/geos/libgeos/commits/svn-3.6) | [](https://ci.appveyor.com/project/OSGeo/geos/branch/svn-3.6) | More on: https://trac.osgeo.org/geos#BuildandInstall ## Building, testing, installing ### Unix Using Autotools: ./autogen.sh # in ${srcdir}, if obtained from SVN or GIT ${srcdir}/configure # in build dir Using CMake: cmake ${srcdir} # in build dir Now, all versions: make make check make install # as root ldconfig # as root ### Microsoft Windows If you use Microsoft Visual C++ (7.1 or later) compiler, you can build GEOS using NMAKE program and provided `makefile.vc` files. If you are building from SVN or GIT checkout, first run: `autogen.bat` Then: nmake /f makefile.vc MSVC_VER=1400 where 1400 is version number of Visual C++ compiler, here Visual C++ 8.0 from Visual Studio 2005 (supported versions are 1300, 1310, 1400, 1500, 1600, 1700, 1800 and 1900). The bootstrap.bat step is required to generate a couple of header files. In order to build debug configuration of GEOS, additional flag `DEBUG=1` is required: nmake /f makefile.vc MSVC_VER=1400 DEBUG=1 ## Client applications ### Using the C interface (recommended) To compile programs against the C lib (recommended): CFLAGS += `geos-config --cflags` LDFLAGS += `geos-config --ldflags` -lgeos_c #include <geos_c.h> Example usage: capi/geostest.c contains basic usage examples. ### Using the C++ interface (discouraged) NB: The C++ interface should not be used directly; the GEOS project views it as a bug for another program to use the C++ interface or even to directly link against the C++ library. The C++ library name will change on every minor release because it is too hard to know if there have been ABI changes. (The C library uses the C++ interface, but the C library follows normal ABI-change-sensitive versioning, so programs that link only against the C library should work without relinking when GEOS is upgraded.) To compile programs against the C++ lib: CFLAGS += `geos-config --cflags` LDFLAGS += `geos-config --ldflags` -lgeos #include <geos.h> Basic usage examples can be found in `doc/example.cpp`. ### Scripting language bindings Ruby bindings are fully supported. To build, use the `--enable-ruby` option when configuring: ./configure ... --enable-ruby Since version 3.6.0 PHP bindings are not included in the core library anymore but available as a separate project: https://git.osgeo.org/gogs/geos/php-geos Since version 3.0, the Python bindings are unsupported. Recommended options: 1. Become or recruit a new maintainer. 2. Use [Shapely](http://pypi.python.org/pypi/Shapely) with Python versions 2.4 or greater. 3. Simply call functions from `libgeos_c` via Python ctypes. ## Documentation To build Doxygen documentation: cd doc make doxygen-html
