Lesson 2: Configuring Your Development Environment

Updated

Overview

In order to use an integrated development environment (IDE) to build an application that uses GeoCalc, some settings in the IDE must be adjusted.  This generally consists of these steps:

  1. Setting a path to the GeoCalc include files

  2. Linking the proper library files and license object into an application

  3. For applications that take advantage of the GeoCalc User Interface controls, a link to the UI library files is also required.

  4. Re-building the application to incorporate any needed modifications

Some environments also require the adjustment of other settings.  Below, you can find specific instructions for configuring the following environments:

 

Microsoft Visual Studio:

  1. Under Project->Properties->C/C++
    • Under General, add the path to the GeoCalcPBW include directory to “Additional Include Directories” (by default “c:\bmg\inc”).
    • Under Code Generation set "Runtime Library" to "Multi-threaded DLL" for the Release configuration or "Multi-threaded Debug DLL" for the Debug configuration
  2. Under Project->Properties->Linker
    • Under General, add the path to the GeoCalcPBW.lib (GeoCalcPBWd.lib for a Debug configuration) file and the path to the license.obj file to “Additional Library Directories” (by default “c:\bmg\lib\GeoCalcPBW[Visual Studio version]\[Debug | Release], c:\bmg\GeoCalcPBW\lic”).
    • Under Input, add GeoCalcPBW.lib (or GeoCalcPBWd.lib) and license.obj to “Additional Dependencies”. If you are using GeoCalc dialogs you will have to add GeoCalcPBWUI.lib (GeoCalcPBWUId.lib) as well.
    • If you are using a Debug configuration, add msvcrt.lib to the ignore library parameter. If you are using a Release configuration, add msvcrtd.lib to the ignore dependency parameter
  3. Close Visual Studio
    • Under start->Control Panel->System->Advanced->Environment Variables
    • Add the full path the Dlls that you will be using to the system variable Path (by default "c:\bmg\GeoCalcPBW\redist[Visual Studio version]\[Debug | Release]")
  4. Open Visual Studio and rebuild the application.

Linux and Mac

  1. Add an include flag to your CFLAGS to the GeoCalc Class Library include directory
    • CFLAGS += -I <path_to_install>/inc
    • CXXFLAGS += -I <path_to_install>/inc
  2. Add a linker flag to add the license object file and the class library
    • LFLAGS +=  <path_to_license>/license.o -L <path_to_install>/GeoCalcPBW/redist -l GeoCalcPBW -lGMLCore -lGeoCalc -lGMLCore -lxerces-c -lxml-security-c -lqt-mt
  3. Make sure that the LD_LIBRARY_PATH includes a reference to the GeoCalc .lib files
  4. Re-build the application.
