[gdal-dev] How to Use Gdal in Microsoft Visual Studio C++

[Ivan Lucena]

Hi Athin,

Just to complement what Mateusz wrote, the project files generated automatically are not a *real* Visual Studio C++ project that you can change parameters on the project's property dialogbox. The generated project is what Microsoft calls a Makefile project. It is just a shell around the existing makefile.vc files. When you click on build all it does is to run "name -f makefile.vc" with some parameters.

So it might not be a good idea if you need to integrate with a VS Solution that need to share settings with other *normal* VC projects. The other options for that would be 'GDAL cmake' [https://trac.osgeo.org/gdal/wiki/CMake] but I never use it.

If all you want to do is to compile GDAL I think you would be better off by using command line tools (edit nmake.local based on nmake.opt and run nmake -f makefile.vc, make, make install). Just like Mateusz said.

The automaticly generated projects would give you a complete code scan with autocompletion, go to declaration, go to definition and refactoring tools, just like in a *normal* Visual Studio project but you still need to edit nmake.local to change setting like debugging mode, for example. And more importantly, I haven't use it for a long time so I almost forgot that you can use it for debugging too.

Good luck!

Ivan

    In order to build and use current GDAL, you need Visual Studio 2015 or later.
    GDAL requires C++11 compiler
    https://trac.osgeo.org/gdal/wiki/rfc68_cplusplus11
    
    You may try VS2013, which offers some C++11 support,
    but it is not guaranteed to work at all.

    For example,
    
    D:\gdal\gdal\> generate_vcxproj.bat 15.0 64 gdal_vs2017
    Generating:
      "D:\gdal\gdal\gdal_vs2017.vcxproj"
      "D:\gdal\gdal\gdal_vs2017.vcxproj.user"
      "D:\gdal\gdal\gdal_vs2017.vcxproj.filters"
      "D:\gdal\autotest\cpp\gdal_vs2017_test.vcxproj"
      "D:\gdal\autotest\cpp\gdal_vs2017_test.vcxproj.user"
      "D:\gdal\autotest\cpp\gdal_vs2017_test.vcxproj.filters"
    This might take a little while...
    Projects done!
    Launch Visual Studio IDE
    * Open project "D:\gdal\gdal\gdal_vs2017.vcxproj"
    * Add  project "D:\gdal\autotest\cpp\gdal_vs2017_test.vcxproj"
    * Configure Build Dependencies to build the main project before the
    test project.
    * Save solution in .sln file
    Done!
    
    Finally, since you asked " guide me how can i use gdal",
    you do not need VS project to build or use GDAL.
    You can build GDAL library from command line using NMAKE and Makefiles provided
    See https://trac.osgeo.org/gdal/wiki/BuildingOnWindows
    (Note, the page has not been updated regarding minimum VS version
    required, so assume it is VS2015).
    Then, create your own application project in VS and configure it
    setting include directories,
    library directories, libraries for linker input.
    If you don't know how to use VS, you will need to learn it from the
    Microsoft docs, eg.
    https://docs.microsoft.com/en-us/cpp/build/vscpp-step-1-create
