Osgearth compilation (reprint)

Osgearth compiling

Osgearth compilation needs OSG and some third-party plug-in library, I mainly refer to the cnblogs on a blog post, but also not enough detail, and I have compiled a good OSG the situation to compile Osgearth, so the period also encountered some problems, I explained in detail below:

• Note: First you need to compile all the plugins and OSG, as well as Osgearth to use the same VS platform, the following compilation is done in VS2008 SP1 environment
• Preparation (refer to Bindings City Prodigal blog)

  The required plugins and libraries for download include:

  Download: http://osgearth.org/wiki/Downloads

  CURL (curl-7.21.7.tar.gz): http://curl.haxx.se/download.html

  GDAL (gdal-1.8.0.tar.gz): Http://trac.osgeo.org/gdal/wiki/DownloadSource

  GEOS (geos-3.2.2.tar.bz2): http://trac.osgeo.org/geos/

  EXE file: Http://files.cnblogs.com/eaglezhao/expat-win32bin-2.0.1.rar

  Libzip (libzip-windows.zip): code:http://nih.at/libzip/

  The compiled package is available for download:

  Vs2008:http://wush.net/trac/osgearth/raw-attachment/wiki/downloads/libzip-windows.zip

  VS2010:

  Http://files.cnblogs.com/eaglezhao/libzip (VS10). rar

  Osgearth (SVN download): Svn:http://svn.github.com/gwaldron/osgearth.git (currently the latest version is Osgearth 2.0)

• Installation:
  • CURL

    Note that you download if the source version, directly compiled with VS2008, you can also download the precompiled version, but there is missing a debug library file.

    After compiling the directory under the Include/curl file copy to E:\OSG\3rdparty\include\curl, to cover

    After compiling the directory under the Lib Libcurl.dll file copied to E:\OSG\3rdparty\bin, to cover

  • GDAL

    After downloading Gdal's source code, you also need to run Makegdal_gen.bat this file first, and then open X:\Program Files\Microsoft Visual Studio\vc98\bin\vcvars32. Bat,x represents your VS installation disk. Switch to your Gdal directory with the CD command after opening, nmake/f Makefile.vc msvc_ver=1500 Build_debug=yes, where 1500 represents vs version 2008, Of course you can also enter NMAKE configuration file modification.

    Gdal compiled files are stored in C:\warmerda\bld, including file Include,lib,data,bin, which can be copied to the Gdal folder and placed under the OSG directory. Finally, the following work is done:

    Copy the. h file under the ALG, Gcore, OGR, and port folders to the include, the generated LIB, DLL includes: Gdal_i.lib gdal.lib cpl.lib (under the port directory) ogr.lib (ogr directory), and Gdal18.dll

    Copy to D:\OSG\GDAL\lib

  • GEOS

    Compile the GEOS by compiling the Gdal consent method. Copy the generated geosd.lib,geos.lib, Geos_c_i.lib, Geosd_c_i.lib to D:\OSG\geos\lib, geos-3.2.2\source\ Copy the GeoS folder under headers to the include.

  The final file structure:

  Note that the inside of the expat I did not use, may have been included in other libraries.

  OSG is already compiled, and the OSG environment variable has been set, then CMake will automatically find your OSG

  The path of the.

• Compiling Osgearth

  Use CMake to open Osgearth cmakeLIsts.txt

  Change Dynamic_osgearth (bool variable) on

  Osg_dir (PATH) x:/osg/openscenegraph

  Specific cmake inside the setting reference:

  The final thing is to delete the contents of the NotFound items, that is, empty.

  Then build vs solution, enter vs after the inside to set the Include file and library file

• After the build is complete, run the install project to build.

  Note to generate debug and release two versions, like OSG, Debug and release version to correspond, otherwise it will be wrong, the corresponding debug command and library files are set separately, otherwise you may not find plug-ins or other problems.

• Environment variable Configuration

  Copy the files under the D:\OSG\OSGEARTH\lib\Debug and release folders to the Debug and release folders under D:\OSG\OSGEARTH\bin, and then run the. exe, which is missing a. dll, and the search is copied in ( Gdal18.dll under the Gdal folder).

  environment variable Settings

  osg_file_path:D: \osg\osgearth\data;d:\osg\gdal\data;

  PATH: e:\osg\3rdparty\bin;d:\osg\osgearth\bin\debug; D:\OSG\OSGEARTH\bin\Release;

  Finally you go from CMD to the tests folder of the source directory to test whether the installation was successful.

  A textured Earth appears, indicating that it has been installed successfully. Otherwise, there is a mistake. Most of the time, the plugin compiles the issue.
