rundemo c++ no datasource

[Jakub Pawlewicz]

Hi all,

I am newbie in mapnik. At the beginning I just wanted to start with rundemo. I have Ubuntu 16.10. I followed instructions in https://github.com/mapnik/mapnik/wiki/UbuntuInstallation. configure says all requirements are met besides icu support in libboost-regex so `make test` fails on 3 tests. However I installed it anyway. Running
$ ./rundemo /usr/local
results in
  running demo ...
### std::exception: Could not create datasource for type: 'shape' (no datasource plugin directories have been successfully registered)

I believe it is some standard problem but my searches for solutions failed after few hours. So what is the clue?

Check if you C++ code has something like

mapnik::datasource_cache::instance().register_datasources("plugindir");

where "plugindir" is /usr/lib/mapnik/input or /usr/lib64/mapnik/input or
wherever your input plugins are installed.

Bye

Well, it showed up that rundemo from directory demo/c++ should be executed from mapnik soruces root directory. Looking into the code of rundemo.cpp gave me some hint, but it should be probably somewhat better documented in the demo. Thanks.
