BUILDING A COMMAND-LINE C++ APPLICATION
7. Update the dependencies line from basic_sample.obj to be for RasterSlope.obj
and to depend on RasterSlope.cpp and RasterSlope.h.
To compile with another development environment,
see Chapter 4, ‘Developer environments’,
or the online Help.
You are now ready to compile with nmake. When this scenario directs you to do
so, you will need to use the “f ” flag to specify the name of the makefile that
should be used. At the command line, you will type:
nmake /f Makefile.Windows.
Setting execution parameters
To use the makefile to facilitate running the scenario, the parameters need to be
stored within it and a target must be set to run the application. To set up your
makefile to do this, you need to update the parameters to match the data you
wish to process and the name you want the output to be given.
1. Near the beginning of Makefile.Windows, find the lines:
Equivalent lines will be found in the makefiles
for each supported platform.
The command-line build tools of Visual Studio
(nmake, cl, link, for example) are not available
by default. However, a batch file provided by
Microsoft makes them available in Windows. This
batch file, called vcvars32.bat, must be run each
time you open a new command prompt. You can
automate this process by either creating a batch
file that runs the Visual Studio 6.0 version of
vcvars32.bat and opens a command prompt that
is ready for development or by using the Visual
Studio .NET 2003 Command Prompt, which
runs vcvars32.bat for you. For details, see the
C++ API section in Chapter 4, ‘Developer
environments’.
#
# Command line parameters: Edit these parameters so that you can
# easily run the sample by typing "nmake /f Makefile.Windows run".
#
# You will need to:
# (1) Describe parameters here. ex: IN_SHAPEFILE is the input shapefile
# (2) Define parameters below this comment box.
# ex: IN_SHAPEFILE = "c:\data\shapefile.shp"
# (3) Add the parameters to the run target at the end of this file
# ex: $(PROGRAM) $(IN_SHAPEFILE)
#
2. Below it, add parameters for running this sample. For example, if your input
raster is “C:\MyComputer\Rasters\RasterDataset” and your output dataset is
going to be named “tempslope”, you will add the following lines:
IN_RASTER = "C:\MyComputer\Rasters\RasterDataset"
OUT_RASTER = "tempslope"
3. At the end of Makefile.Windows there is a run target that currently only
executes the program. Update that run target to also pass in the input parameters.
If you used the variable names IN_RASTER and OUT_RASTER as shown in the
example above, the run target should now look as follows:
#
# Run target: "nmake /f Makefile.Windows run" to execute the application
#
run:
$(PROGRAM) $(IN_RASTER) $(OUT_RASTER)
You are now ready to run the application with nmake. When this scenario directs
you to do so, you will need to use the “f ” flag to specify the name of the makefile
that should be used. On a Windows system, you will type:
nmake /f Makefile.Windows run
