## rundemo.cpp
|
||||
|
||||
This directory contains a simple c++ program demonstrating the Mapnik C++ API. It mimics the python 'rundemo.py' example with a couple exceptions.
|
||||
|
||||
If building on unix you can have this program automatically build by configuring Mapnik like:
|
||||
|
||||
./configure DEMO=True
|
||||
|
||||
However, this example code also should be able to be built standalone.
|
||||
|
||||
The following notes describe how to do that on various operating systems.
|
||||
|
||||
## Depends
|
||||
|
||||
- Mapnik library development headers
|
||||
- `mapnik-config` on unix and `mapnik-config.bat` on windows
|
||||
|
||||
### Unix
|
||||
|
||||
On OS X and Linux you also need `make`.
|
||||
|
||||
### Windows
|
||||
|
||||
On windows, additional dependencies to build are:
|
||||
|
||||
- MSVS 2010 with C++ compiler
|
||||
- Python 2.x
|
||||
- gyp: https://code.google.com/p/gyp | https://github.com/springmeyer/hello-gyp
|
||||
|
||||
`mapnik-config.bat` should come with your Mapnik installation.
|
||||
|
||||
First confirm it is on your path:
|
||||
|
||||
mapnik-config # should give usage
|
||||
|
||||
To install gyp, which is pure python do:
|
||||
|
||||
svn checkout http://gyp.googlecode.com/svn/trunk/ gyp
|
||||
cd gyp
|
||||
sudo python setup.py install
|
||||
|
||||
|
||||
## Building the demo
|
||||
|
||||
### Unix
|
||||
|
||||
Simply type:
|
||||
|
||||
make
|
||||
|
||||
Then to run do:
|
||||
|
||||
./rundemo `mapnik-config --prefix`
|
||||
|
||||
On OS X you can also create an xcode project:
|
||||
|
||||
gyp rundemo.gyp --depth=. -f xcode --generator-output=./build/
|
||||
xcodebuild -project ./build/rundemo.xcodeproj
|
||||
./build/out/Release/rundemo `mapnik-config --prefix`
|
||||
|
||||
|
||||
### Windows
|
||||
|
||||
First you need to build he visual studio files with gyp:
|
||||
|
||||
gyp rundemo.gyp --depth=. -f msvs -G msvs_version=2010
|
||||
|
||||
Then you can compile the demo with `msbuild`:
|
||||
|
||||
msbuild build.sln

This directory contains a simple c++ program demonstrating the Mapnik C++ API. It mimics the python 'rundemo.py' example with a couple exceptions.
|
||||
|
||||
To build it re-configure SCons with DEMO=True then rebuild::
|
||||
|
||||
$ python scons/scons.py configure DEMO=True
|
||||
$ python scons/scons.py
|
||||
|
||||
|
||||
The sample program will be compiled (but not installed).
|
||||
|
||||
|
||||
To run::
|
||||
|
||||
$ cd demo/c++
|
||||
$ ./rundemo /usr/local/lib/mapnik
|
||||
|
||||
For more detailed comments have a look in demo/python/rundemo.py
|
||||
|
||||
Have fun!

||||
